AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1030 AM PST SUN FEB 24 2008

.DISCUSSION...
VERTICALLY STACKED SYSTEM APPROACHING THE NRN CA COAST FORECAST TO
MOVE ACROSS THE CA/OR BORDER AREA WITH UPPER SYSTEM OPENING UP TO A
WAVE. SURFACE LOW HAS BEEN STEADILY FILLING AS IT HAS APPROACHED THE
COAST...AND WILL CONTINUE TO DO SO TODAY AS IT MOVES INLAND WITH THE
OPEN WAVE. THE STRONGEST UP VALLEY RDD-SAC GRADIENT IS OCCURRING NOW
WITH THE CHICO PROFILER SHOWING 50+ KT WINDS ABOVE 1500 FT. THESE
WINDS FORECAST TO DECREASE AFT 18Z ACCORDING TO THE NAM12 925 MBS
WIND PROGS...AND STATUS/TIMING OF WIND ADVSRYS LOOK GOOD EXCEPT FOR
ZONES 18/19 WHERE WINDS HAVE ALREADY DECREASED.

BACK EDGE OF PCPN/ENHANCED CLOUDS ACCORDING TO SATELLITE AND RADAR
ARE CURRENTLY ALONG THE COAST. NWS SPEED TOOL EXTRAPOLATION SUGGESTS
THE BACK EDGE WILL BE NEAR THE ERN SIDE OF THE VLY OR SIERNEV
FOOTHILLS BY 23Z. THE NAM CAPE/LI FIELDS INDICATE THAT THIS AREA
WILL BE MARGINALLY UNSTABLE THIS AFTN AND WE BELIEVE THIS IS WHERE
WE WILL POSSIBLY SEE SOME ISOLATED THUNDERSTORMS DEVELOPING. THE
BACK EDGE IS ENHANCING ALONG THE WINDWARD SIDE OF THE COASTAL RANGE
AND IS ALSO THE LIKELY THE PRECURSOR TO THE COLDER MORE UNSTABLE AIR
THAT WILL BE MOVING EWD THIS AFTN. HELICITY VALUES FROM BUFKIT DATA
CONTINUE TO BE VERY IMPRESSIVE...BUT WITH CLOUDY SKIES...COOL
TEMPS/DEWPOINTS IN THE 40S/50S NOT TOO SURE HOW UNSTABLE IT WILL BE
THIS AFTERNOON UNLESS WE SEE SOME CLEARING. LAPSE RATES OFF BUFKIT
DATA INDICATE THAT AT LEAST THERE IS DEEPER INSTABILITY FORECAST FOR
THE SCK SITE...THAN ANY OF THE SITES FURTHER N...AND THIS ALONE
WOULD FAVOR THE SAN JOAQUIN VLY/MOTHERLODE AREAS. THE INDIRECT
CIRCULATION OF THE 2ND SPEED MAX ON THE BACK SIDE OF THE UPPER LOW
IS FORECAST TO MOVE INTO INTERIOR NORCAL THIS EVENING WHICH MAY ALSO
ENHANCE UVVS IN THIS AREA.

AS THE CLOSED LOW OPENS UP...THERE WILL BE BETTER OROGRAPHICS FOR
THE SIERNEV...AND THE SNOW WILL CONTINUE TO PILE UP IN THE SIERNEV.
PROFILES INDICATE SNOW LEVELS WILL RANGE FROM 4600 TO 5200 FT AT CIC
AND SHS. THESE LEVELS HAVE RISEN SINCE THE ONSET OF THE PCPN
YESTERDAY AS THE DRIER SUB CLOUD LAYER WHICH LED TO EVAPORATIVE
COOLING AND LOWERING SNOW LEVELS...FINALLY MOISTENED. SHS PROFILER
INDICATED A RISE FROM 3300 FT TO 5200 03Z SUN AS THE SLY WINDS
INCREASED TO 50 KTS. SNOW REPORTS FROM THE SIERNEV INDICATED ABOUT
12-18 INCHES ACCUMULATED...AND FROM 18Z SUN TO 12Z MON BUFKIT
INDICATES GENERALLY SIMILAR ACCUMULATIONS...BUT WITH THE TPW PLUME
PUSHED FURTHER S THERE WILL BE LOWER PWS TO WORK WITH DURING THIS
TIME.

THE PCPN AND WIND WILL DECREASE BY SUN NITE/MON MORNING AS WHAT IS
LEFT OF THE STORM SYSTEM MOVES INTO THE DESERT SW. A HIGHLY
AMPLIFIED RIDGE WILL THEN BUILD ALONG THE COAST FOR SOME MILD
TRANQUIL WX EARLY NEXT WEEK. MUCH OF NEXT WEEK ALSO LOOKS DRY...
EXCEPT FOR A COUPLE OF WEAK FRONTS THAT ARE PROGGED TO MOVE ACROSS
NORCAL ON WED AND AGAIN FRI. SOME LIGHT PRECIP MAY ACCOMPANY THESE
FRONTS...BUT HAVE LEFT WED DRY FOR NOW. THE 12Z SUN RUN OF THE GFS
DIGS THE SYSTEM OFF THE CA COAST ON WED MORE SO THAN THE EURO...BUT
LITTLE IF ANY QPF IS EXPECTED IN INTERIOR NORCAL WITH THESE
SYSTEMS.    JHM

&&

.AVIATION...
LOW PRESSURE IS MOVING ONSHORE THIS MORNING NEAR EUREKA. THERE ARE
WIDESPREAD RAIN SHOWERS IN THE VALLEY AND SNOW IN THE MOUNTAINS
ABOVE 3500-4000 FEET. A STRONG PRESSURE GRADIENT FROM THE LOW IS
BRINGING WINDY CONDITIONS OUT OF THE SOUTH ACROSS THE SACRAMENTO
VALLEY...WITH THE STRONGEST GUSTS IN THE NORTHERN END...REACHING 43
KT AT KRBL. WINDS IN THE NORTHERN SAN JOAQUIN MAY GUST TO AROUND 27
KT LATE THIS MORNING. WINDS SPEEDS OVER THE AREA WILL GRADUALLY
DIMINISH LATER THIS AFTERNOON. GENERAL MVFR CONDITIONS WILL IMPROVE
TO TO VFR AFTER 06Z TONIGHT. ISOLATED THUNDERSTORMS ARE POSSIBLE
THIS AFTERNOON INTO THE EVENING OVER VALLEY AND SIERRA FOOTHILLS
WITH LOCALLY STRONG WIND GUSTS OR SMALL HAIL POSSIBLE. LINGERING
