210 PM PST SAT FEB 1 2003

UPPER LEVEL SHORTWAVE WILL MOVE QUICKLY SOUTHEAST ACROSS THE AREA
TONITE. A NARROW BAND OF PRECIP WAS MOVING SE ACROSS THE NORTHERN
SIERRA AND WAS APPROACHING YNP. HAVE KEPT SOME SMALL CHANCE POPS IN
THE HIGHER ELEVATIONS OF THE SRN SIERRA THRU 12Z. DIFFUSE FRONT WILL
MOVE THRU THE AREA THIS EVE. MAIN IMPACT WILL BE TO LIFT THE VALLEY
STRATUS...WITH CLEARING SKIES. AFTER FROPA HOWEVER...LOOKS LIKE
PLENTY OF RESIDUAL MOISTURE WILL REMAIN BANKED UP ON THE EAST SIDE
AND SOUTH END OF THE VALLEY AND ADJACENT FOOTHILLS...AND IT WILL
EXTEND INTO THE PASSES OF THE TEHACHAPIS. THUS...A MOCLDY FCST
TONITE THESE AREAS...WHILE REMAINDER OF THE REGION CLEARS. THE LOW
CLOUDS SHOULD BEGIN TO DISSIPATE SUN AFTERNOON AS FLOW DRIES AND
BECOMES NORTHERLY. WINDS IN THE KERN MTNS/DESERTS WILL PICK UP MORE
THIS EVE AND CONT THRU SUN MORNING. HOWEVER...IT NOW LOOKS LIKE
WINDS WILL BE MARGINAL ADVISORY CRITERIA. WILL THEREFORE DOWNGRADE
HIGH WIND WATCH FOR THESE AREAS TO WIND ADVISORY. THE WINDS WILL
BECOME MORE NORTHERLY AND BEGIN DECREASING SUN AFTERNOON INTO THE
EVENING.

FOR SUN NITE THRU TUES...HIGH AMPLITUDE RIDGE WILL BE BUILDING IN
THE EAST PAC. THIS WILL KEEP SKIES GENERALLY CLEAR. VALLEY FOG LOOKS
PATCHY THRU TUES MORNING. COLD ADVECTION BEHIND TONITES FRONT WILL
ALSO BRING THE THREAT OF FROST TO THE SJV BEGINNING SUN NITE. WHILE
A STRONG NORTHERLY FLOW DEVELOPS OVER THE AREA...THE SURFACE HIGH
THAT BUILDS INTO NORCAL AND THE GREAT BASIN IS NOT OF ARCTIC ORIGIN.
THUS...DO NOT AT THIS TIME EXPECT A WIDESPREAD FREEZE IN THE SJV.
THOUGH MORNINGS WILL BE FROSTY IN PLACES MON AND TUES.  BINGHAM

THE EXTENDED PERIOD (WED THRU SAT)...PROGS INDICATING HIGH AMPLITUDE
RIDGE NEAR 130W WEDNESDAY WHICH EITHER REMAINS IN PLACE OR
RETROGRADES WEST FROM 135W TO 140W THURSDAY...DEPENDING ON THE MODEL
FOLLOWED...SINCE EACH MODEL PROG SEEMS TO HAVE A SLIGHTLY DIFFERENT
HANDLE ON A DRY UPPER LOW DROPPING SOUTHWEST FROM THE INTERMOUNTAIN
WEST INTO CENTRAL CA BY 12Z FRI. THE UKMET/ECMWF/GEM ARE A BIT
STRONGER AND FURTHER WEST THAN THE GFS WHICH KEEPS THE LOW EAST OF
THE SIERRAS. NO MATTER WHICH SOLUTION VERIFIES...A REINFORCING SHOT
OF COOL AIR IS EXPECTED THURSDAY AS THICKNESSES AND 850 MB TEMPS
FALL. RH PROGS REMAIN DRY FOR THE MOST PART...EXCEPT FOR A SHOT OF
MID/UPPER MOISTURE BRUSHING THE YOSEMITE AREA WEDNESDAY NIGHT AS THE
UKMET/ECMWF/GEM SUGGEST. EXPECT BELOW NORMAL TEMPERATURES WEDNESDAY
WITH FURTHER COOLING EXPECTED BY THURSDAY THEN ONLY A SLOW
MODERATING TREND THROUGH NEXT WEEKEND. LATE NIGHT/MORNING FROST IN
THE SAN JOAQUIN VALLEY WILL BE THE MAIN ISSUE THROUGH THE PERIOD.  DS
