AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
925 AM PST SUN FEB 12 2012

.SYNOPSIS...
COOL AND UNSETTLED WEATHER WILL CONTINUE ACROSS THE REGION THROUGH
AT LEAST TUESDAY...WITH SHOWERS POSSIBLE...MAINLY WEST OF THE
MOUNTAINS.  MODERATE TO STRONG AND GUSTY WEST WINDS WILL ALSO
CONTINUE ACROSS THE MOUNTAINS AND DESERTS.  AS THE NEXT SYSTEM DIGS
OVER THE REGION MONDAY AFTERNOON AND EVENING...A SLIGHT CHANCE OF
THUNDERSTORMS WILL ALSO BE POSSIBLE.  ALTHOUGH ANOTHER SYSTEM MAY
APPROACH THE REGION WEDNESDAY OR THURSDAY...A GRADUAL WARMING AND
DRYING TREND WILL OCCUR LATER THIS WEEK.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

WATER VAPOR IMAGERY CONTINUES TO SHOW THE UPPER LEVEL TROUGH OF LOW
PRESSURE PUSHING INTO UTAH AND ARIZONA THIS MORNING...AS A WEAK
DISTURBANCE MOVES AROUND THE BACK SIDE NEAR LAS VEGAS AND DAGGETT.
THIS IS PROVIDING ENOUGH INSTABILITY TO PRODUCE SOME SHOWERS WITHIN
THE MARINE LAYER ALONG AND WEST OF THE MOUNTAINS.  THE COMPOSITE
RADAR IMAGERY SHOWS THESE ISOLATED TO SCATTERED SHOWERS WELL...WITH
THE BRUNT OF THE SHOWERS CURRENTLY MOVING INTO SAN DIEGO COUNTY.
ALTHOUGH THE WAVE MOVES THROUGH THE REGION THIS MORNING...THE MODELS
ARE SUGGESTING THAT ISOLATED SHOWERS COULD BE POSSIBLE THROUGHOUT
THE DAY TODAY...MAINLY FAVORING THE COASTAL SLOPES.
THEREFORE...EXPECT ANY PRECIPITATION TODAY TO BE LIGHT ONCE
AGAIN...WITH A FEW HUNDREDTHS OR MAYBE A TENTH OF AN INCH AT BEST.
OTHERWISE...EXPECT SOME SUN BREAKS TO BE POSSIBLE WEST OF THE
MOUNTAINS...WITH SUNNY SKIES OF THE DESERTS.  TEMPERATURES WILL BE A
LITTLE WARMER TODAY...BUT STILL WELL BELOW NORMAL FOR MOST AREAS.
MEANWHILE...THE MOUNTAINS AND DESERTS WILL CONTINUE TO SEE SOME
MODERATELY GUSTY WEST WINDS TODAY.

WATER VAPOR IMAGERY ALSO SHOWS THE THE NEXT SYSTEM STARTING TO
DEVELOP NEAR 45 NORTH AND 135 WEST...AND WILL DIG SOUTHWARD ACROSS
CALIFORNIA ON MONDAY.  THIS MEANS THAT MORE COLD AND SHOWERY WEATHER
WILL CONTINUE ACROSS THE REGION FOR MONDAY AND MONDAY NIGHT.  AT
THIS POINT IN TIME...IT APPEARS THAT PRECIPITATION WILL START AS
EARLY AS MONDAY MORNING ACROSS THE NORTHERN AREAS...AND THEN REALLY
DEVELOP BY THE AFTERNOON AND EVENING HOURS.  THIS WILL BE A MUCH
COLDER SYSTEM.  TEMPERATURES AT 850 MBS FALL TO BETWEEN 0 AND 2
DEGREES C BY MONDAY AFTERNOON AND WELL BELOW ZERO BY MONDAY NIGHT.
THE 700 MBS TEMPERATURES ALSO FALL TO BETWEEN -8 AND -11 DEGREES C
BY MONDAY NIGHT...WHICH SUGGEST THAT SNOW LEVELS WILL LIKELY FALL
BELOW 4000 FEET DURING THE OVERNIGHT HOURS...AND MAY BE LOCALLY
LOWER WITH THE HEAVIER SHOWERS.  THERE IS ALSO ENOUGH INSTABILITY
WITH THIS SYSTEM...THAT A SLIGHT CHANCE OF THUNDERSTORMS WILL BE
POSSIBLE MONDAY AFTERNOON AND EVENING.

THE REAL QUESTION WITH THIS NEXT SYSTEM WILL BE WITH THE
PRECIPITATION AMOUNTS?  AT THIS TIME...MOST OF THE MODELS CONTINUES
TO SHOW A RELATIVELY SHALLOW MOISTURE LAYER...WITH PRECIPITABLE
WATER VALUES FALLING FROM A PEAK OF 0.8 INCHES MONDAY MORNING TO
AROUND 0.4 INCHES OR LESS BY MONDAY AFTERNOON.  THEREFORE...THE
MARINE LAYER WILL ONCE AGAIN BE THE LIKELY MOISTURE SOURCE...AND
THAT PRECIPITATION AMOUNTS WILL ONCE AGAIN BE ON THE LIGHT SIDE.
HOWEVER...GIVEN THE INSTABILITY...IT IS PROBABLE THAT SOME MODERATE
OR HEAVIER SHOWERS WILL DEVELOP.  THE 06Z LOCAL WRF IS REALLY
HINTING AT THIS HAPPENING...FOCUSING UPWARDS TO A HALF INCH ALONG
SOME OF THE COASTAL SLOPES.  IF THIS HAPPENS...SOME OF THE MOUNTAIN
AREAS COULD SEE A DECENT AMOUNT OF NEW SNOW FALL...AND MAY NEED TO
CONSIDER SOME WINTER WEATHER PRODUCTS.

THE OTHER CONCERN WITH THIS SYSTEM WILL BE WITH THE WINDS IN THE
MOUNTAINS AND DESERTS.  AT THIS TIME...IT APPEARS THAT THE ONSHORE
GRADIENTS WILL BE TIGHTER TOMORROW...WITH UPPER LEVEL WIND SUPPORT
AT 850 MBS INCREASING TO BETWEEN 35 AND 55 KNOTS.  THE 700 MBS WINDS
SUPPORT IS EVEN STRONGER...RANGING BETWEEN 50 AND 60 KNOTS.
THEREFORE...THE HIGH WINDS WATCHES REMAIN IN PLACES FOR THE
MOUNTAINS AND DESERTS...AND WILL LIKELY BE UPGRADED WITH THE
AFTERNOON PACKAGE IF THE REST OF THE 12Z MODELS AGREE...WHICH IS THE
CASE THUS FAR.

ALTHOUGH SHOWERS WILL LINGER ACROSS THE AREA ON TUESDAY...DRIER
CONDITIONS WILL DEVELOP BY TUESDAY NIGHT.  MODELS ARE CONTINUES TO
STRUGGLE WITH THE NEXT UPPER LEVEL LOW FOR THE WEDNESDAY OR THURSDAY
TIME FRAME.  AT THIS TIME...THE 12Z GFS SEEMS TO BE THE MOST
CONSISTENCE OVER THE PAST FEW RUNS...TRACKING THE SYSTEM DOWN THE
CALIFORNIA COAST AND BRINGING MORE PRECIPITATION TO THE REGION ON
WEDNESDAY AND WEDNESDAY NIGHT.  HOWEVER...IT IS STILL THE MOST
WESTWARD OF THE MODELS.  MEANWHILE...THE 00Z ECMWF HAS NOW TAKEN A
MORE INSIDE TRACK ONCE AGAIN...DROPPING THE LOW ACROSS THE
INTERMOUNTAIN WEST WEDNESDAY AND INTO THE DESERT SOUTHWEST WEDNESDAY
NIGHT.  ALTHOUGH IT STILL A MORE INSIDE TRACK...IT DOES TRY TO
GENERATE SOME LIGHT PRECIPITATION OVER THE REGION WEDNESDAY NIGHT
AND THURSDAY.  AS FOR THE 00Z GEM...IT IS THE FARTHER EAST OF THE
MODELS...AND THE 00Z UKMET IS THE ALSO SOMEWHERE IN BETWEEN.  GIVEN
THE MODEL SPREAD AND TIMING ISSUES...CONFIDENCE IS LOW AS TO WHAT
WILL HAPPEN AT THIS TIME.

THE EXTENDED MODELS THEN GRADUALLY WARM AND DRY THINGS OUT FOR THE
REMAINDER OF THE WORK WEEK...BUT ARE NOW HINTING THAT ANOTHER TROUGH
WILL DIG OVER THE REGION FOR LATE SATURDAY AND INTO SUNDAY.
