AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PST SAT JAN 26 2008

.SYNOPSIS...A DEEP UPPER-LEVEL LOW OFF THE COAST WILL DRAW
SUBTROPICAL AIR NORTHWARD TODAY. LIGHT RAIN IS EXPECTED TO DEVELOP
LATE THIS AFTERNOON...THEN INCREASE IN INTENSITY TONIGHT ALONG WITH
GUSTY WINDS. WINTER STORM CONDITIONS WILL LIKELY MAKE TRAVEL VERY
DIFFICULT AT HIGHER ELEVATIONS IN THE NORTHERN MOUNTAIN AREAS
OVERNIGHT...WHILE HEAVY RAIN IS POSSIBLE AT LOWER ELEVATIONS. THE
HEAVY SHOWERS AND POSSIBLE THUNDERSTORMS WILL CONTINUE INTO SUNDAY
NIGHT...THEN TAPER OFF MONDAY...BUT COOL WEATHER WILL CONTINUE WITH
SCATTERED SHOWERS POSSIBLE THROUGH EARLY NEXT WEEK.

&&

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

IR SATELLITE IMAGERY SHOWS A COLD UPPER LOW CENTER CONTINUING TO
DROP SOUTH NEAR 33N/132W OR ABOUT 725 MILES W OF POINT CONCEPTION.
BAROCLINIC LEAF STRETCHES ALMOST NORTH-SOUTH WELL OFF THE COAST.
FARTHER SOUTH IR ENHANCEMENT IS RAPIDLY INCREASING TO NEAR 30N/188W
OR ABOUT 240 MILES SW OF SAN DIEGO. THIS ENHANCEMENT IS OCCURRING
JUST TO THE SOUTH OF THE CORE OF THE SUBTROPICAL JET. CLOSER TO
HOME AT 1630Z...VISIBLE IMAGERY SHOWS SKIES ARE CLEAR OVER NORTHERN
PORTIONS OF THE CWA WHILE HIGH CLOUDS ARE THICKENING OVER SAN DIEGO
COUNTY. NWS RADAR IS BEGINNING TO DETECT LIGHT ECHOES NOW SOUTH OF
TIJUANA MOVING NE. THE SURFACE PRESSURE GRADIENTS ARE WEAK AND
WINDS MOSTLY LIGHT EXCEPT FOR EASTERN SECTIONS OF THE MOUNTAINS
WHERE SOME EAST WINDS HAVE BEGUN TO GUST OVER 20 MPH. TEMPERATURES
WERE MOSTLY IN THE 40S AND 50S.

LITTLE CHANGE IN PREVIOUS THINKING AT THIS TIME BASED ON CURSORY
ANALYSIS OF THE LATEST 12Z MODEL DATA. IT APPEARS THAT RAIN WILL
OVERSPREAD THE AREA FROM THE SW LATER TODAY AS WARMER AND MORE MOIST
AIR FROM THE S...OVERRUNS THE COOLER AIR OVER SOCAL. IT WILL NOT BE
AS CLEAR CUT FOR NORTHERN MOUNTAIN AREAS. IF LOWER LEVEL WINDS
BACK ENOUGH...THE SNOW LEVEL MAY REMAIN AT OR BELOW RESORT LEVELS
UNTIL LATER TONIGHT OR SUN MORNING. THAT COULD MEAN MORE HEAVY SNOW
BEFORE THE SNOW LEVEL LIFTS SUNDAY MORNING. IN ANY CASE...THE RAIN
AND SNOWFALL WILL BE HEAVY AND LIKELY TO CAUSE PROBLEMS SO A WINTER
STORM WARNING WILL BE ISSUED FOR TONIGHT. FOR THE SAN DIEGO COUNTY
MOUNTAINS...HEAVY SNOWFALL IS NOT EXPECTED UNTIL POSSIBLY LATE ON
SUN OR SUN NIGHT.

THE UPPER-LEVEL LOW OFF THE COAST MAKES IT TO ABOUT 32N LATER
TONIGHT BEFORE IT EJECTS TO THE NE AND ENDS UP NEAR POINT CONCEPTION
BY SUN EVENING. THE MODELS EJECT A LOBE OF VORTICITY FROM THE LOW
TONIGHT...WHICH ENHANCES THE PRECIPITATION AND THE WINDS OVER SOCAL.
WIND ADVISORIES MAY BE NEEDED OVER MOST OF THE FORECAST AREA AFTER
10 PM PST BASED ON MODEL GUIDANCE. GUSTY WINDS AND PERIODS OF RAIN
ARE LIKELY TO CONTINUE THROUGH SUN AND INCREASE AGAIN WITH A CHANCE
OF THUNDERSTORMS AS THE COLD UPPER LOW CENTER MOVES CLOSER TO THE
COAST SUN NIGHT. MAIN UPSLOPE ENHANCEMENT OF PRECIPITATION WILL BE
FOR THE TRANSVERSE RANGES (S FACING SLOPES) TONIGHT THROUGH SUN...
SHIFTING TO THE PENINSULAR RANGES (WEST FACING SLOPES) BY SUN NIGHT
AND CONTINUING THROUGH MON.

THE MAIN MECHANISM FOR PRECIPITATION TONIGHT WILL BE OVERRUNNING...
ENHANCED BY SOME UPSLOPE FLOW...WHILE INSTABILITY AND UPSLOPE FLOW
DOMINATES SUN AND SUN NIGHT. THIS WILL BE ENHANCED BY A PERIOD
STRONG OF SYNOPTIC LIFT SUN NIGHT AS THE MAIN SYSTEM AND JET MAX
MOVES THROUGH. MOIST WESTERLY FLOW WILL KEEP PRECIPITATION GOING ON
THE WEST SLOPES MON...BUT IT SHOULD TAPER OFF ELSEWHERE. RAINFALL
SHOULD BE SUBSTANTIAL TO HEAVY MOST AREAS. SEE LATEST FFASGX FOR
DETAILS.

&&

261530Z...VARIABLE AMOUNTS OF MID AND HIGH CLOUDS WITH BASES MOSTLY
AT OR ABOVE 8000 FEET MSL WILL COVER THE AREA THROUGH THIS
AFTERNOON. EXPECT BASES TO LOWER LATE THIS AFTERNOON AND EVENING TO
BETWEEN 3000 AND 5000 FEET AS MAIN BAND OF CLOUDS AND SHOWERS OFF
THE COAST MOVES TOWARDS THE COAST. BASES WILL CONTINUE TO LOWER
THROUGH THE EVENING ALONG WITH RAIN SPREADING OVER THE AREA. BASES
SHOULD LOWER TO BETWEEN 1000 AND 2500 FEET MSL. VISIBILITIES SHOULD
LOWER TO 1 TO 3 MILES IN MODERATE TO HEAVY RAIN AT TIMES THROUGH THE
NIGHT. SHOWERS...HEAVY AT TIMES...WILL CONTINUE THROUGH THE
AFTERNOON ON SUNDAY.

GUSTY SOUTH TO SOUTHWEST WINDS SHOULD ALSO BE EXPECTED THIS EVENING
AND OVERNIGHT AT COASTAL AIRPORTS SUCH AS KSAN AND KSNA. THE WIND
SHOULD BECOME MORE SOUTHWESTERLY ON SUNDAY BUT REMAIN GUSTY THROUGH
SUNDAY NIGHT.  HORTON

&&

.MARINE...
261530Z...STRONG GUSTY WINDS WILL DEVELOP IN THE COASTAL WATERS
TONIGHT THROUGH SUNDAY MORNING. WINDS ARE EXPECTED TO BE 25 TO 30 KT
WITH GUSTS TO 35 TO 40 KT. SOME DECREASE IN THE WIND SUNDAY MORNING
BUT WIND SHOULD PICK UP AGAIN SUNDAY EVENING AND NIGHT. HEAVY RAIN
WILL DEVELOP TONIGHT THROUGH SUNDAY MORNING WITH SHOWERS THROUGH
MONDAY AFTERNOON. AN UNSTABLE AIR MASS WILL MOVE OVER SUNDAY WITH
THE POTENTIAL FOR THUNDERSTORMS AND FUNNEL CLOUDS OR WATERSPOUTS.
