Looks like the warm weather we've had for much of the spring is going to come to an end soon, just in time for Memorial Day weekend - the unofficial start of summer, in most parts of the country - but for Southern California's, often the start of the infamous May Gray/June Gloom season.
An unseasonably deep closed low is expected to sit and spin around the Pacific Northwest for an undetermined period of time, possibly bringing record low high temperatures there. Down here it will just deepen the marine layer and bring relentless onshore flow, drizzle, slow to no clearing, and cool to cold weather.

.SYNOPSIS... MARINE LAYER LOW CLOUDS RETURN TO THE COASTAL AREAS TONIGHT...BURNING OFF AROUND MID MORNING ON TUESDAY. MOSTLY SUNNY BUT NOT AS WARM ON TUESDAY. NOTICEABLY COOLER FOR WEDNESDAY AND THURSDAY WITH THE MARINE LAYER LOW CLOUDS EXTENDING INLAND TO THE FOOTHILLS DURING THE NIGHTS AND MORNINGS. PATCHY DRIZZLE WILL BE POSSIBLE WEST OF THE MOUNTAINS ON THURSDAY MORNING. DAYTIME TEMPERATURES WILL REMAIN BELOW SEASONAL AVERAGES THROUGH EARLY NEXT WEEK...WITH ONLY MINOR DAY TO DAY VARIATIONS. GUSTY WEST WINDS WILL ALSO DEVELOP EACH AFTERNOON AND EVENING IN THE MOUNTAINS AND DESERTS...WITH THE STRONGEST WINDS ON THURSDAY.
There is even a possibility of some rain by next Tuesday, but the uncertainty for this is very high.

As of 3:12 am this morning, the Winter season has started. The sun reached its furthest southern declination and is now returning north. Today is the shortest day of the year. For Southern Orange County the length of day is about 9 hours and 55 minutes with a sunrise at 6:51 am and a sunset at 4:46 pm. The earliest sunset, however, happened over 2 weeks ago, about 4 1/2 minutes earlier than today and the latest sunrise will not be until early January, about 4 1/2 minutes later than today.
Weather forecast for California has a few storms with a period of unsettled weather Saturday (Dec. 22) afternoon through Monday. For Christmas Day and the following day we get a break before the next series of storms is forecasted to hit. Unlike last year at this time, which was dominated by warm, sunny offshore flow, even the dry days are expected to be cool with very cold nights. Temperatures this morning got down to 12 F in the high desert and to the 30s in some coastal areas of Southern California.

This morning we surprisingly have a deep and tropical-like marine layer which is being advected in from the remnants of Hurricane Paul. Temperatures stayed in the mid-70s for many coastal areas overnight, which is VERY unusual for late October. Also, this is one day after offshore flow brought temperatures in the 100s to some areas, so it is a very quick resurgance of the marine layer. Patchy clouds are already near the coastal slopes of the mountains.
After 4 days of hot offshore flow, much cooler weather is in the forecast. The marine layer has deepened well ahead of schedule. The remnant upper low from Paul will affect us over the weekend before a deep trough develops over the West Coast and persists through much of next week. Earlier forecasts said major precipitation was possible over Southern California mid-week, but have backed off on that for now. Areas north of Pt. Conception should get still some rain and possibly high elevation snow. South of Pt. Conception may get drizzle from the deep marine layer.
The following is an excerpt from the NWS San Diego forecast discussion this morning, issued at 9:25 am.
WATER VAPOR IMAGERY CONTINUES TO SHOW HIGH PRESSURE CENTERED TO OUR
NORTH...AND AN UPPER LEVEL SPINNING NEAR 25 NORTH AND 122 WEST THIS
MORNING. WATER VAPOR IMAGERY ALSO SHOWS THE REMNANTS OF PAUL
LIFTING NORTHWARD TOWARDS THE SOUTHLAND FROM THIS UPPER LEVEL
LOW...WHICH BROUGHT A MARINE LAYER SURGE AS WELL AS LEGITIMATE WARM
FRONT ACROSS THE REGION LAST NIGHT. MOST OF THE MARINE BUOYS AND
COASTAL OBSERVING LOCATIONS PICKED UP ON THE WARM FRONT...WITH A
RAPID RISE IN PRESSURE AND SOUTHERLY WIND SHIFT. IN FACT...A GOOD
EXAMPLE OF THIS IS FROM LINDBERGH FIELD...WHERE THE WINDS WENT FROM
CALM OR LIGHT EASTERLY TO SOUTHERLY AROUND MIDNIGHT...AND STARTING
GUSTING OVER 30 KTS. ALTHOUGH LINDBERGH DID NOT REALLY SEE THE
INCREASE IN ITS TEMPERATURE WITH THE WIND SHIFT...OTHER LOCATIONS
DID...SUCH AS JOHN WAYNE AND FULLERTON.
THIS WARM FRONT MADE FROM A VERY MILD AND BORDERLINE WARM MORNING
ACROSS THE REGION...WITH TEMPERATURES AT 6 AM THIS MORNING RUNNING 5
TO 15 DEGREES ABOVE WHERE THEY WERE AT THAT TIME YESTERDAY.
ALTHOUGH MOST LOCATIONS ARE STILL SHOWING THIS TREND...A FEW
LOCATIONS ARE NOW MORE SIMILAR TO THEIR TEMPERATURE AT THIS TIME
YESTERDAY. THIS IS THE FIRST CONCERN LEADING INTO OUR CURRENT
FORECAST. THE SECOND IS DECENT EAST WINDS ON THE CURRENT KNKX VAD
WIND PROFILE AT 4000 FEET AND ABOVE...SUSTAINED BETWEEN 15 AND 25
KTS. IT IS FEASIBLE THAT THESE WINDS COULD HELP MIX THE MARINE
LAYER OUT...WARMING TEMPERATURES SIMILAR TO WHERE THEY WERE
YESTERDAY. AM ALSO WATCHING THE LOW CLOUDS OUT THE WINDOW...WHICH
ARE CURRENTLY MOVING SOUTHERLY OR SOUTHWESTERLY WITH THESE
WINDS...SO THE ABOVE IS A VIABLE SOLUTION TO THE FORECAST TODAY.
HOWEVER...THE 12Z KNKX SOUNDING SHOWED NEARLY 8 DEGREES OF COOLING
AT 950 MBS...AND THE HIGH RESOLUTION MODELS ARE SHOWING THE LOW
CLOUDS LINGERING FOR MUCH OF THE DAY. THEY ARE ALSO SHOWING THAT
THE OFFSHORE GRADIENTS WILL TURN ONSHORE BY THIS AFTERNOON.
THEREFORE...CONFIDENCE IS LOW AS TO WHAT WILL ACTUALLY HAPPEN. FOR
NOW...WILL KEEP THE CURRENT FORECAST AS IS...BUT WILL SERIOUSLY
WATCH THE SKY CONDITIONS AND TEMPERATURES...AS PAUL STARTS TO GET
PULLED MORE WESTERLY WITH SUPPOSEDLY LESS INFLUENCE THE AREA.
THE COOLING TREND SHOULD CONTINUE THROUGH THE WEEKEND...AS THE MAIN
UPPER LEVEL LOW NEAR 25 NORTH AND 122 WEST SLOWLY DRIFTS NORTHWARD
TOWARDS SOUTHERN CALIFORNIA...BEFORE MOVING INLAND ACROSS BAJA ON
SATURDAY NIGHT. THEREFORE...EXPECT COOLER CONDITIONS TO
DEVELOP...ALONG WITH INCREASING ONSHORE FLOW AND A DEEPENING MARINE
LAYER. THE MARINE LAYER WILL DEEPEN ENOUGH THAT SOME DRIZZLE WILL
LIKELY BE POSSIBLE ALONG AND WEST OF THE MOUNTAINS THIS WEEKEND.
WILL ALSO WATCH THE POTENTIAL SURGE OF MOISTURE NORTHWARD TO SEE IF
SOMETHING MORE MAY BE POSSIBLE.
AS THIS UPPER LEVEL LOW EXITS THE REGION...A DEEP TROUGH OF LOW
PRESSURE WILL DEVELOP ALONG THE WEST COAST ON SUNDAY...AND REMAIN IN
PACE THROUGH MUCH OF NEXT WEEK. THEREFORE...EXPECT THE COOLER
CONDITIONS TO CONTINUE ACROSS THE REGION...ALONG WITH A RELATIVELY
DEEP MARINE LAYER. THE ONSHORE GRADIENTS WILL REMAIN ELEVATED AS
WELL...WITH GUSTY SOUTHWEST TO WEST WINDS POSSIBLE EACH AFTERNOON
AND EVENING IN THE MOUNTAINS AND ALONG THE DESERT SLOPES.

What are your preferred thermostat settings for the summer and winter?
During the winter we usually have it at 73 during the day and 71 during the night, but that's because my mom is extremely sensitive to cold. During the summer we usually have it between 78 and 80 during the day and keep it off during the night. Nights in California are relatively cool even in the summer.
However, I know this strange guy who says they have the heat on 74 in the winter and have the AC on about 66 during the summer. It's crazy, I know, but apparently they want to feel that their house is much different than outside.

Happy Leap Day everyone. Really, today is a special day and they should make it a holiday. With the years divisible by 100 NOT being leap years unless they are also divisible by 400, we actually have 365.2425 days to one revolution around the Sun.
We are much more likely to set weather records today than any other day as there are about 4 times less days to have already set records.
Finally, I bring up an interesting question:
What day was it a year ago today?
It was not 2/28/2011 (year ago from yesterday) and it was not 3/1/2011 (year ago from tomorrow), so what day was it? I'd call it an imaginary day, 2/29i/2011.
