January 2009 Jan. 26 - Unpredictable Weather? Two periods of rain were recently forecast in Southern California -- one from Wednesday into Saturday, and another from Sunday evening into Tuesday. Model projections varied from day to day and run to run. At one time it looked like the Los Angeles area might get about an inch or rain out of both systems. So what happened?
Jan. 20 - Ten Consecutive Days with Highs in the Eighties. Rain on the Way. Including today, Los Angeles has enjoyed an unprecedented ten straight January days with highs in the eighties. In the yin yang of weather, the western half of the U.S. has been enjoying unusually warm temps, while the eastern half of the country has shivered.
December 2008

Dec. 25 - Storm Misses Los Angeles. Trough Producing Some Rain & Snow. A Pacific storm system -- which at one point was expected to be the wettest of the rain season thus far -- took a more westward track and skirted the coast of Southern California on Christmas Eve, generally producing only modest rainfall across the area.
Dec. 23 - Potent Pacific Storm Takes Aim at California. A potent appearing Pacific storm system is developing off the coast of Oregon and Northern California and headed our way. Significant rain, with snow at the higher elevations, is expected over much of the state.
Dec. 18 - Rain, Snow, and Blustery Winds in Southern California. High Impact Weather for Christmas? A cold upper level low produced widespread rain and snow in Southern California, closing highways, fouling traffic, and chilling Southlanders. As much as a foot of snow was reported in the Antelope Valley and the snow level dropped to near 2000 ft in the foothills and mountains of Ventura and Los Angeles counties.
Dec. 16 - Back to Back Upper Level Lows. An intense upper level low, fed in part by moisture that originated in the subtropical mid-Pacific, produced widespread rain in Southern California, with snow at the higher elevations. Precipitation totals generally ranged from about 1 to 3 inches, and new rainfall records for December 15 were set at LAX, UCLA, Long Beach, San Gabriel and Santa Barbara.
Dec. 12 - Wintry Weather Expected in Southland. Downtown Los Angeles (USC) rainfall has dropped to about six-tenths of an inch below normal. If a storm later this weekend works out as expected, we could be back above normal by Monday night.

November 2008 Nov. 27 - Rainfall Records Broken in Southern California. Rainfall totals for the storm have generally ranged from 1.0 to 2.0 inches in the coastal and valley areas, with some higher amounts recorded in foothill and mountain locations. Rainfall records for November 26th were broken at several locations, including Lancaster, Palmdale, Sandberg, UCLA, Burbank, Woodland Hills, and San Gabriel. OPIDS Camp, in the San Gabriel Mountains has recorded 3.29 inches.
Nov. 24 - Upper Low Expected to Drench Southern California. NOAA Releases Winter Precipitation Outlook. HPC projects from one to two inches of rain over a large area of Southern California. NOAA 2008-2009 Winter Outlook indicates an equal chance of below normal, near normal, or above normal precipitation for California.
October 2008 Oct. 31 - Halloween Showers? Winter Precipitation Outlook. Downtown Los Angeles (USC) records 0.02 inch of rain. There's a continuing chance of showers in Southern California through the weekend. Winter precipitation outlook with a La Nina flavor -- similar to last year.
Oct. 1 - Clouds, Heat, and then Rain? Downtown Los Angeles records a trace of rain, and a few other stations in Southern California recordmeager, but measurable, precipitation. Front associated with the trough is currently forecast to hold together south of Pt. Conception and could produce some showers in the Los Angeles area.
July 2008 Jul. 15 - Monsoon Pattern Results in Flash Floods & Debris Flows. Monsoonal flow that began last Thursday has resulted in numerous thunderstorms in the mountains and deserts of Southern California, with flash flooding and debris flows reported in several locations.
June 2008 Jun. 20 - Heat Wave Expected to Peak Today. Equatorial Pacific in Transition. Temperatures today at Los Angeles Pierce College in Woodland Hills appear to be running about a degree hotter than yesterday, when a new record high for the date of 109°F was recorded at the campus weather station. Equatorial Pacific SSTs continue the transition to neutral conditions. This TAO section plot of 5-day Depth Average Temperature clearly shows the change in state with a marked increase in sub-surface temperatures, particularly in the far eastern and western equatorial Pacific.
May 2008 May 23 - Cold Upper Low Generates Extreme Weather in Southland. More Wet Weather Possible Today and Tomorrow. The unseasonably energetic upper level low that replaced our unseasonably strong high has resulted in dramatic weather in Southern California, including heavy rain, hail, thunderstorms, lightning, and even a pair of tornadoes near March Air Force base.
May 17 - Strong Pacific Jetstream Pumps Up West Coast Ridge & Temperatures. Chance of a Shower Next Weekend? Yesterday, Woodland Hills set a new high temperature record for the date of 101°F. Record high temperatures were also recorded at Ojai, Sandberg, Santa Ana, El Cajon, Red Bluff, Redding, Sacramento, Stockton, Modesto, San Jose, Eureka and several other stations in California. Triple digit highs were recorded across much of the interior of the state. GFS, ECMWF and other guidance is suggesting that as the extended Pacific jet collapses, the west coast ridge will retrograde off the coast and be replaced by a trough by Memorial Day Weekend.
May 1 - La Niña Fades as Rain Season Nears End. In it's April 30 ENSO Wrap-Up, the Australian Bureau of Meteorology characterizes Pacific climate patterns as being generally neutral, "with the majority of indicators returning to near-normal levels." We've had only a smattering of rain at Downtown Los Angeles since 0.46 inch was recorded back on February 24. A miniscule 0.01 inch was recorded on March 15, and 0.04 inch on April 2.
April 2008 Apr. 1 - More Than April Showers? A blustery Spring storm is expected to produce measurable rain over much of Southern California tomorrow. As has often been the case this year, the 12z NAM and 12z GFS are at odds, with the NAM generating less than 0.25 inch at Los Angeles, and the GFS more than 0.5 inch.
March 2008 Mar. 30 - Weak Front Dampens Southland. Water Year Rainfall Total Falls Below Normal. Only 0.01 inch of rain was recorded at Downtown Los Angeles (USC- KCQT) the entire month of March, pulling the water year rainfall total more than a 0.5 inch below normal for the first time this rain season.
February 2008

Feb. 25 - Pacific Storm Soaks California -- Dumps More Snow in Sierra. Weather conditions were tough for the Amgen Tour of California cyclists cranking over Mill Creek Summit yesterday. The Mill Creek RAWS recorded an average temperature of 35°F, with winds of 25 mph, gusting to 40 mph, at about the time the peloton cleared the summit. Since mid-week last week some Sierra snow sensors have recorded as much as 8 or 9 inches snow water equivalent of precipitation -- the rough equivalent of 6 or 7 feet of snow. Today's Statewide Summary of Snow Water Equivalents, provided by the California Cooperative Snow Surveys, reports the Sierra snowpack at 119% of normal for the date and 101% of the average April 1 seasonal total.
Feb. 22 - Intense Pacific Storm Approaching West Coast. Rapidly intensifying Pacific low pressure system approaching the west coast looks very impressive on satellite images this afternoon, with strong upper and low level jet dynamics, a good moisture feed, and a classic baroclinic leaf.
Feb. 21 - Extended Pacific Jet Sends Us Some Rain! Precipitation totals from the first of a series of shortwaves associated with a extended Pacific jetstream produced rainfall amounts ranging from about 0.1 to 0.25 inch in the Los Angeles area yesterday, with up to about 0.5 inch recorded in some mountain locations.
Feb. 14 - Trough Wetter Than Expected. Pattern Change Next Week? A more westward position of the upper low than forecast by yesterday's 18z GFS and NAM, has resulted in a more vigorous system that has produced rain in several areas of the Southland and snow in the mountains.The last few runs of the GFS have been indicating a transition back to a wetter pattern around mid-week of next week, when a strong Pacific jet and a series of shortwave troughs are forecast to target the west coast.
Feb. 5 - Western Drought Severity Lessens. More Rain For Los Angeles, More Snow For The Sierra. Sunday's storm added more rain to Southern California's unexpectedly wet water year totals, and more snow to the Sierra snowpack. This rain season western storms have reduced drought classifications by as much as three steps in some areas of California and four in Arizona. Sierra snow course measurements for February 1 are coming in and manual measurements are confirming what automatic snow sensors have already reported -- that the Sierra snowpack is well above normal for the date.

January 2008

Jan. 28 - Eight Days of Los Angeles Rain One of Longest Wet Periods on Record. According to NWS Preliminary Climatology Data (CF6), Downtown Los Angeles has recorded measurable rain on each of eight days from January 21 to January 28, 2008. This puts it in the top six of the station's wettest periods from 1921-2007.
Jan. 25 - Heavy Rain Expected Overnight Saturday. The extensive circulation around an upper level low is forecast to interact with the southern branch of the jet stream and an associated plume of sub-tropical moisture, and draw the jet and moisture into Southern California overnight on Saturday.
Jan. 24 - New Upper Level Low May Tap Tropical Moisture. You can see why the weather models had such a tough time with yesterday's forecast for Los Angeles. Much of the day the main rain band associated with the upper level low spinning off the coast was stalled and producing moderate to heavy rain in areas of Ventura, Santa Barbara and San Luis Obispo counties. New daily rainfall records were set at Santa Barbara, Santa Maria, and Paso Robles airports.
Jan. 22 - Upper Level Low Spinning Showers into Southern California -- Heavier Rain May Be On Tap. In a rain season characterized by upper level lows, yet another one has set up shop off the coast and has been sending some showers our way. As of 8:00 a.m. this morning rainfall totals around the Los Angeles area have generally ranged from a few hundredths of an inch to as much as about 0.25 inch in a few locations.
Jan 7. - Series of Storms Soaks West. Precipitation totals in the Los Angeles area from Friday morning to this morning generally ranged from 2-5 inches in the basin and valleys, and from 5 to 10 inches or more in the local foothills and mountains. San Marcos Pass, near Santa Barbara recorded nearly 11 inches of rain, and OPIDS Camp, near Mt. Wilson, recorded nearly 13 inches of precipitation.

December 2007 Dec. 31 - Strong Pacific Storm Forecast to Pound State. Los Angeles will end 2007 with precipitation for the water year close to normal, and with the Sierra snowpack at about 60% of normal. However the first week of 2008 may usher in one of the strongest Pacific storms to affect California in some time.
Dec. 20 - Unusual La Niña Precipitation Pattern in the West. According to preliminary NWS data, Downtown Los Angeles (CQT) recorded 1.24 inches of rain as a result of Tuesday night's storm, bringing the water year total to 3.69 inches. This amount is about 3/4 inch above normal for the date.
Dec. 17 - More Rainfall Forecast for Los Angeles. SREF Ensembles have been trending wetter south of Pt. Conception over the next 36 hours with each run. The 15z run indicates >90% chance of the rainfall total exceeding 0.1 inch in the Los Angeles area for the 24 hr. period ending 7:00 a.m. Wednesday.
Dec. 8 - Los Angeles Rainfall Continues Above Normal. Downtown Los Angeles (CQT) recorded 0.41 inch of rain, bringing the water year total (since July 1) up to 2.44 inches -- still 0.16 inch above normal for the date. Last year at this time only 0.50 inch had been recorded.
Dec. 1 - Los Angeles Rainfall Above Normal? In a November where the other 29 days were bone dry, the 30th was surprisingly wet, with downtown Los Angeles (CQT) recording 0.56 inch of much needed rain. The storm brought the water year total (since July 1) for Los Angeles to 2.03 inches, which is a deceptive 0.15 inch above normal for the date.
November 2007 Nov. 29 - Waiting For Rain. NOAA Updates Winter Outlook. This morning's 3-day precipitation forecast from the HPC showed no precipitation in our area, but the 09z SREF, 12z NAM, and 12z GFS all suggested the likelihood of at least a little rain in Los Angeles county, and the midday update of the HPC forecast now includes some green here. NOAA released its updated Winter Outlook November 15 and the NDJ outlook for Southern California precipitation continues to be bleak.
October 2007 Oct. 13 - Upper Level Low Wetter Than Expected. An upper level low that was expected to produce only a chance of scattered showers south of Pt. Conception has resulted in more rain at Downtown Los Angeles (USC) in an 8 hour period than was recorded in any month of last year's rain season!
Oct. 9 - Southern California 2007-2008 Winter Precipitation Outlook. NOAA released its initial Winter Outlook for the U.S. today, including a Dec-Jan-Feb precipitation outlook. The precipitation pattern projected for the western U.S. is typical of a La Niña, with an increased chance of higher than normal precipitation in the Pacific northwest and an increased chance of lower than normal precipitation in the southwest.
September 2007 Sep. 23 - September Storm Socks Southland. Several Southland locations recorded new rainfall records for the date on Friday and Saturday. Downtown Los Angeles set a new maximum rainfall record of 0.40 inch for September 22, exceeding the previous record of 0.15 inch set in 2000.
Sep. 19 - Record Setting September Storm? An unusually cold, deep and energetic upper level low is forecast to affect the area over the next 2-3 days. The system could set new rainfall and temperature records for Downtown Los Angeles (USC) and other Southern California locations.
August 2007

Aug. 31 - Heat Wave Expected to Continue. Los Angeles Pierce College in Woodland Hills recorded a high temperature of 109°F on Wednesday and Thursday, and so far today has reached a temperature of about 108°F. The hot weather is expected to continue through Labor Day, along with periods of higher than normal humidity.
Aug. 27 - Hurricane Dean Moisture Produces Some Showers. Remnant moisture from Hurricane Dean produced a few showers around the area over the weekend.
Aug. 24 - Cool July! Southern California Winter Precipitation Outlook. Have you noticed it's been cooler this summer? Last year Pierce College in Woodland Hills recorded a high temperature of at least 100°F on 25 of 31 days in July, culminating in a sweltering record high of 119°F. This year only 10 days in July reached the 100° mark at the school. Virtually all international dynamic coupled climate models are forecasting cooler equatorial Pacific SSTs this Fall, trending towards neutral conditions this Spring. As a result, most longer range outlooks are similar to the Nov-Dec-Jan Precipitation Outlook from the CPC, and somewhat typical of a La Niña, with an increased chance of higher than normal precipitation in the Pacific northwest and a increased chance of lower than normal precipitation in the southwest.

July 2007

Jul. 4 - Driest Water Year On Record. There was no measurable rain recorded this May or June at Downtown Los Angeles (USC). The most recent measurable rain was on April 22 when 0.04 inch of rain was recorded. From July 1, 2006 to June 30, 2007, Los Angeles recorded only 3.21 inches of rain, breaking the record set in 2001-2002 as the driest year since recordkeeping began in 1877.
Jul. 24 - A Little Rain is Better Than None! Although only a trace of rain was observed at Downtown Los Angeles (USC) yesterday, several stations in Los Angeles County recorded some precipitation. Rainfall amounts ranged from 0.01 inch or so, to as much as 0.15 inch at Opids Camp in the San Gabriel Mountains.

May 2007 May 30 - Driest Year on Record Appears Likely. There's a little drizzle around the Los Angeles area this morning, but it would take much more than a light mist to make up the nearly one foot deficit in Los Angeles rainfall. Los Angeles' rainfall total remains at 3.21 inches for a water year that began on July 1, 2006 and will end June 30, 2007. Normal rainfall would be 15.14 inches.
April 2007

Apr. 23 - Wettest Day in Driest Year? Friday's vigorous system produced 0.50 inch of rain at Downtown Los Angeles (USC). According to the NWS, this is the latest date in the water year that Los Angeles has recorded it's first day of 0.5 inch, or more, of rain.
Apr. 16 - Scattered Showers in Southern California. Downtown Los Angeles (USC) was one of just a few places in Southern California that received measurable rain yesterday as a result of moisture wrapping around a late season upper low.

March 2007 Mar. 26 - Cloudy, Breezy & Cool — A Chance of Showers, and Maybe a Thundershower. Some showers around the area. From July 1, 2006 to March 25, 2007 Downtown Los Angeles (USC) has recorded only 2.47 inches of rain. This is 11.04 inches below normal.
February 2007

Feb. 1 - July-January 5th Driest on Record. Warm Superbowl Sunday. Pattern Change Ahead? While some locations in the Los Angeles area were pounded by heavy showers on Tuesday, with rain rates on the order of a 0.25 inch/hour, Downtown Los Angeles (USC) recorded only 0.02 inch of rain. This increased the water year total (since July 1) to 1.50 inches, which is 5.62 below normal, and the 5th driest water year on record.
Feb. 9 - Will Los Angeles Be Short-Changed Again? A strong Pacific storm system with a very moist sub-tropical connection is forecast to produce more than an inch of precipitation over much of California the next 72 hours, with as much as 5 inches (liquid equivalent) forecast in some areas of the central Sierra Nevada. Given our meager amount of rainfall this rain season, it is unfortunate that the projected amount of precipitation falls off dramatically south of Santa Barbara.
Feb. 19 - Rainy Monday with More on the Way? Upper low and trough has produced widely varying rainfall intensities and amounts across the area, with CNRFC reporting as little as 0.01 inch at Malibu, and as much as 0.71 inch at Browns Canyon for the 24 hr. period ending at 8:00 a.m. So far Downtown Los Angeles (USC) as recorded 0.03 inch since midnight and 0.09 inch the last 24 hours.
Feb. 28 - Two Fronts — Not Enough Rain. Only the first of two cold fronts held together well enough to produce measurable rain throughout the Los Angeles area. Rainfall amounts from Monday's frontal passage generally ranged from few hundredths to a few tenths in the basin and valleys, with up to an inch or so in the mountains. Downtown Los Angeles (USC) recorded 0.04 inch of rain on Monday, no rain on Tuesday, and a trace of precipitation today, bringing the water year total to 2.42 inches, which is 8.38 inches below normal. This is less rainfall for the date than in the record dry water year of 2001-2002.

January 2007

Jan. 6 - Wind Instead of Rain. Frigid End of the Week? El Niño May Have Peaked. So far this rain season passing cold fronts have stirred up more wind than rain. This was the case again overnight Thursday. A weakening cold front produced little precipitation, but its passage generated winds in excess of 80 mph at the Cheeseboro RAWS near Agoura, and Whitaker Peak RAWS along the I-5 corridor south of Gorman. Dr. Klaus Wolter's Multivariate ENSO Index (MEI) for November/December decreased from 1.293 to 0.985. This resulted in the biggest one-month drop in MEI rank on record for this time of year.
Jan. 15 - Record Low Temperatures. Drought Continues. Usual El Niño Impacts Still On Hold. Chance of Showers? Many new record low temperatures for the date were set across the area early Sunday morning, including Downtown Los Angeles at 36°F, Burbank at 26°F, Long Beach at 31°F, Palmdale 10°F, and Lancaster at a frigid 3°F. Woodland Hills tied the record for the date at 20°F, as did the Santa Monica Pier at 39°F. According to the NWS Climate Report for January 14, 2007, Los Angeles (USC) has recorded only 1.31 inches of rain since the water year began on July 1.
Jan. 26 - Chance of Weekend Showers. January One of the Driest on Record? So far this January Downtown Los Angeles (USC) has recorded only 0.01 inch of rain. This makes it a contender for one of the driest Januarys on record. Where it will rank depends on the amount of rain a cut-off upper low currently spinning off the California coast generates in the Los Angeles area over the next few days.
Jan. 29 - Continuing Chance of Showers. July-January One of the Driest on Record. According to the NWS Climate Reports, Los Angeles (USC) recorded only 0.16 inch of rain on Saturday, and none on Sunday. This brings the preliminary January rainfall total to 0.17 inch – tied with January 1984 as the 10th driest on record – and the water year total (since July 1) to 1.48 inches. A water year total less than 1.72 inches on February 1 would rank this season's July-January rainfall as the 5th driest on record.

December 2006

Dec. 8 - Change to More Seasonable Pattern? MEI Exceeds Strong El Niño Threshold. If the computer weather models have their way, it looks like some cooler, wetter weather will be moving into Southern California this weekend. It's already raining up in the Bay area, and Intellicast composite radar shows the rain band down to about Pt. Conception. Dr. Klaus Wolter's Multivariate ENSO Index (MEI) for October/November increased from 1.03 to 1.29. This moves the MEI above the strong El Niño threshold, as defined by the index. It is the 5th highest MEI for all October-November values (since 1950). and is the highest ranked value since April-May 1998.
Dec. 15 - Difficult Forecast for the Weekend. The computer weather models have been having a tough time getting a handle on the system forecast to move through Southern California this weekend. While there's a pretty good chance it will be damp, blustery, and cool much of this weekend, the difficult question is just how damp will it get?
Dec. 26 - Another Difficult Forecast. Yet again this rain season, computer weather models have been having a tough time with the forecast, and seem to be understating precipitation amounts for the storm expected to affect the area over the next 24 hours or so.

November 2006

Nov. 9 - November Temperatures Soar. El Niño Continues to Strengthen. Slight Chance of a Shower? Woodland Hills' (Pierce College) high temperature of 101°F on Tuesday was the highest November temperature ever recorded there. Downtown Los Angeles' 97°F set a new record for the date, and it was the highest temperature ever recorded by the station so late in the season. Many other stations around the area also set new record highs.
Nov. 24 - NOAA Releases Updated Winter Outlook. Chance of Showers Monday. Warm November. El Niño Continues to Strengthen. NOAA released its final Winter Outlook for the 2006-2007 U.S. Winter season on November 16. The revised outlook indicates a somewhat better chance of a wetter than normal Winter in Southern California, than the outlook issued October 19. It's been warm this November. Downtown Los Angeles (USC) set new high temperature records for the date on November 6, November 7 and November 20. The average high temperature the first 22 days of November was 81.4°F, which is about 7°F above normal.

October 2006

Oct. 2 - First Autumn Showers. NOAA Issues Unscheduled El Niño Advisory. TAO/TRITON Moorings Vandalized. The first widespread measurable rain of the 2006-2007 rain season moved into Southern California yesterday, and continued overnight. In an unscheduled advisory, issued September 13, 2006, NOAA announced that El Niño conditions had developed in the tropical Pacific and could strengthen into a moderate event by winter.
Oct. 13 - Chance of Showers. MEI Above Moderate El Niño Threshold. Initial NOAA Winter Outlook Released. An upper level low that produced several inches of snow at South Lake Tahoe and Mammoth Mountain earlier this week is now located off the coast of Southern California and spinning bands of showers into the area. Dr. Klaus Wolter's Multivariate ENSO Index (MEI) for August/September increased to 0.892. This moves the MEI to just above the moderate El Niño threshold.
Oct. 30 - NOAA Releases Updated Winter Outlook. El Niño Continues to Strengthen. Over the past three weeks the Southern Oscillation Index (SOI) has dropped from about -8 to about -16 and another westerly windburst has occurred in the western equatorial Pacific. TAO/TRITON 5-Day Depth Averaged Temperature data shows two large areas of anomalies of 1.7 °C or more. No El Niño impacts here yet, just great Autumn weather.

September 2006

Sep. 14 - A Few Sprinkles Around Southland. MEI Exceeds El Niño Threshold. A shortwave wrinkle in a broad upper trough over the West, associated vorticity, and an 80 kt. jet max nosing into Southern California combined to produce a few showers in the area this morning. Dr. Klaus Wolter's Multivariate ENSO Index (MEI) for July/August increased to 0.75, and moves the MEI well above the weak El Niño threshold.

August 2006

Aug. 3 - Record July Heat. New El Niño Developing? This July you didn't have to run an ultramarathon in Death Valley to experience extreme heat. According to the NWS, Pierce College in Woodland Hills recorded a new all time high temperature for that station of 119°F. This was the highest temperature ever recorded at an NWS observation site in Los Angeles County. Triple digit highs were recorded at Pierce College a record 24 days of July.
Aug. 18 - Westerly Windbursts May Signal El Niño Onset. TAO/TRITON zonal wind data and Climate Data Assimilation System (CDAS) 850-hPa Wind Anomalies indicate a westerly windburst is occurring in the western equatorial Pacific. Dr. Klaus Wolter's Multivariate ENSO Index (MEI) for June/July increased to 0.64, and as Dr. Wolter points out, this is a an increase of more than 1.2 standard deviations in three months, and moves the MEI above the weak El Nino threshold.

July 2006 Jul. 3 - June Hot -- Rest of the Summer Hotter? Based on (preliminary) climate data for Burbank's Bob Hope Airport from the NWS, the average daily temperature was more than 7 °F higher this year than last. In June 2005, only 2 days recorded a high temperature of 90°F, or above, and the highest temperature recorded was only 91°F. This June, 13 days saw the thermometer hit 90°F or above, and the highest temp was 102°F.
Jul. 21 - Heat Wave Continues. New El Niño Developing? However you want to look at it, it has been a hot summer. Based on (preliminary) NWS climate data for Burbank's Bob Hope Airport, June was hot, and the first 20 days of July have been even hotter. At times, higher than normal humidity has increased the discomfort. The NWS climate data for Bob Hope Airport shows that, on average, July has been nearly 6°F warmer than June, and about 6°F warmer than normal. In June the average high temperature at Burbank Airport was 87°F. So far this July it has averaged 94°F.
June 2006

Jun. 9 - Marine Layer Produces Some Drizzle. Passage of a weak upper trough has deepened the marine layer and produced some drizzle overnight, and this morning, in the Los Angeles basin and valleys. As of 8:00 this morning, LAX has recorded 0.01 inch of precipitation, and several other stations have recorded amounts ranging from a trace to 0.01 inches.

May 2006

May 18 - Summer Monsoon, to be Followed by Winter Rain? So far this year we've had eighty degree temps in February, foothill snow in March, and record rain in April; so why not a Summer monsoon pattern in May, followed by an unseasonably strong Winter-like Pacific storm system?
May 22 - Rainfall Record Set in 1921 Broken. According to a NWS preliminary Record Event Report, released at 12:50 this afternoon, Downtown Los Angeles (USC) has recorded 0.67 inches of rain so far today, surpassing a record of 0.33 inches set in 1921. As of 11:00 A.M., the NWS reports that the total rainfall recorded at Los Angeles (USC) for the storm has been 0.84 inches.

April 2006

Apr. 5 - Record Rain in Los Angeles -- Record Snow at Mammoth Mountain! The strong Pacific low pressure system that has been spinning off the West coast since Sunday is finally moving onshore this morning. The late season low has been pumping copious amounts of sub-tropical moisture into the state, resulting in moderate to heavy rain in many areas, swollen rivers and creeks, and heavy snow at the higher elevations of the Sierra. According to preliminary NWS data, Downtown Los Angeles (USC) set a new rainfall record of 1.44 inches yesterday, breaking the record for the date set in 1921.
Apr. 10 - Chance of a Shower Over Next 24 Hours. Chance of Rain Friday? composite radar from 6:30 this morning shows a precipitation band associated with an embedded shortwave and persistent upper level trough along the coast of California. As the current trough moves onshore, it is replaced by yet another upper level trough and its associated surface low. The system is forecast to cut-off, and like most cut-off upper lows, creates a great deal of uncertainty in the forecast -- like when, where and how much precipitation?
Apr. 12 - Rain Forecast for Friday. GOES-10 water vapor image show huge upper level low over the eastern Pacific with quasi-stationary frontal zone impacting the Monterey and San Francisco areas, northward. RAMDIS shows the center of circulation more or less stationary, with the low continuing to extend southward, and some eastward movement of the frontal boundary.
Apr. 14 - More Seasonable Weather Forecast for Southern California. Remember the weather just before Valentine's Day? On February 13th Los Angeles (USC) recorded a high temperature of 86 degrees. Just a week later it snowed in the foothills, and it seems like it's been cool with showers or rain every few days ever since.
Apr. 26 - Neverending Cool Pattern Continues. Chance of Showers and Thunderstorms in Southern California. La Niña Wanes. Another upper level low, the latest in our series of upper level lows, is spinning off the coast of Southern California this morning, and producing showers and thunderstorms to the north of Pt, Conception and in the San Joaquin Valley.

March 2006

Mar. 3 - Series of Systems Forecast for California. Chance of Showers Monday. Weak La Niña Rebounds. Frontal zone associated with Pacific low pressure system is working its way through Southern California this morning. composite radar from 6:15 shows a mix of light, moderate, and some heavier showers around the area.
Mar. 9 - Chance of Low Elevation Snow in Southern California. The third in a week-long series of northern stream Pacific low pressure troughs is digging into the West today and is expected to produce rain and snow throughout much of California over the next 48 hours or so. A combination of low freezing levels and convection could result in snow flurries down into the 1500-2000 ft. range in the Los Angeles area overnight Friday.
Mar. 11 - Low Elevation Snow in Southern California! This morning, at about 2000 ft. in the Simi Hills, periodic snow showers added a white accent to the black, brown, and greens of a landscape in the process of recovering from the Topanga Fire.
