AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1010 AM PST SAT FEB 23 2008

.DISCUSSION...
THE LEADING EDGE OF THE BAROCLINIC LEAF HAS MADE ITS WAY ONSHORE
OVER NORCAL WITH LIGHT PCPN SHOWING UP ON THE AREA RADARS. THIS WARM
FRONTAL PCPN HAS NOT TAPPED THE TPW PLUME THAT EXTENDS FROM OFF THE
BAJA/SOCAL COAST AND WWD TO HI...OR WHAT HAS BEEN ENTRAINED INTO THE
DEEP VERTICALLY STACKED LOW VCNTY 37N/135W. FOR EXAMPLE THE MORNING
RAOB FROM KOAK INDICATED PW OF ONLY .45 INCHES. THE INITIAL LOW PW
IS ALSO EVIDENT ON THE SOUNDING IN A VERY DRY SUB CLOUD LAYER.
HOWEVER...WE SHOULD SEE THE PWS MOISTEN RAPIDLY TODAY AND OVERNIGHT
AS THE JET CORE ROUNDS THE BASE OF THE LOW AND BEGINS TO LIFT NEWD
WITH NORCAL IN THE INDIRECT CIRCULATION OF THE JET AFT 00Z SUN. THE
COLD OPEN CELLULAR CU EVIDENT IN THE IMAGERY INDICATES THE DYNAMIC
NATURE OF THIS SYSTEM...AND THIS COLD AIR AND SHORT WAVE ENERGY WILL
ALSO BE MOVING INLAND AFT 00Z. JUST OFF THE COAST...THE TRANSVERSE
CLOUD BANDS ENHANCING ALONG THE PW PLUME ENTRAINED INTO THE UPPER
LOW INDICATE THAT THE DYNAMICS ARE BEGINNING TO INTERACT WITH THE PW
PLUME...AND THE PCPN WILL INCREASE OVER NORCAL BETWEEN 00Z-06Z SUN.
PCPN EXPECTED TO CONTINUE THROUGH SUN AS THE OFFSHORE SYSTEM MOVES
INLAND AS AN OPEN WAVE. AS THIS SYSTEM OPENS UP... OROGRAPHICS WILL
BE MORE FAVORABLE FOR THE SIERNEV...AS INITIALLY THE STRONG SELY OR
SLY FLOW WILL FAVOR THE COASTAL MTNS AND SHASTA DRAINAGE OVERNIGHT.
MODELS INDICATE THAT THE WAA MAY BE STRONG ENOUGH TO RAISE THE SNOW
LEVELS ABOVE 5000 FEET OVER THE SIERNEV AT TIMES...MAINLY ON SUN...
AHEAD OF THE OFFSHORE COLD FRONT.

AS FOR THE WIND...NAM 925 MBS AND CANSAC DATA INDICATE INCREASING S
OR SELY WINDS PRIMARILY AFT 03Z...ALTHO THEY BOTH INDICATE AN
INCREASE IN WIND IN THE NRN SAN JOAQUIN VLY LATER THIS AFTN. THIS IS
A RESULT OF THE INCREASING E-W GRADIENT WITH THE DEEP SURFACE LOW
OFFSHORE. THIS DATA INDICATE THE WIND WILL BE INCREASING INITIALLY
OVER THE SRN PORTION OF OUR FORECAST AREA CIRCA 00Z...AND THEN
SPREADING NWD THRU SUN. PLANNING ON ISSUING AN ADVSRY FOR THE WATCH
AREA...XCP A HIGH WIND WARNING FOR THE CENTRAL AND NRN SAC VLY WHERE
THE STRONGEST WINDS ARE FORECAST. THE TIME FRAME OF THE STRONGEST
WINDS LOOKS TO BE FROM 12Z-18Z SUN.

THE PCPN AND WIND WILL DECREASE SUN NITE AS 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.   JHM

.AVIATION...
VFR CONDITIONS THIS MORNING OVER THE SACRAMENTO VALLEY ARE GIVING
WAY TO MVFR CEILINGS AS LOWER CLOUDS MOVE IN. IT IS RAINING AT KRDD
AND RAINED BRIEFLY AT KRBL. RAIN BANDS ALONG THE COAST ARE SPREADING
TO THE NORTHEAST AND ARE EXPECTED TO BRING WIDESPREAD PRECIPITATION
OVER THE AREA BY THIS AFTERNOON. THERE ARE LOCAL IFR/MVFR CIGS AND
VISIBILITIES IN THE DELTA...NORTHERN SAN JOAQUIN VALLEY AND
BEGINNING TO EXTEND INTO THE SOUTHERN SACRAMENTO VALLEY. GUSTY WINDS
WILL DEVELOP OVER THE NORTHERN SAN JOAQUIN VALLEY THIS AFTERNOON AND
SPREAD NORTHWARD INTO SACRAMENTO VALLEY IN THE LATE AFTERNOON AND
EVENING...WITH SOUTHEASTERLY GUSTS TO 35 KT. WINDS WILL INCREASE
FURTHER OVERNIGHT AND CONTINUE INTO SUNDAY MORNING. IFR/LIFR
