AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
430 AM PST SAT FEB 24 2007

.DISCUSSION...
WARM FRONTAL CLOUDS HAVE SPREAD SEWD OVER MUCH OF THE INTERIOR OF
NORCAL TONITE...AND AT PRESS TIME WERE SURGING SE OF THE I-80
CORRIDOR. VERTICAL MOTION QUITE WEAK THIS MORNING AND ONLY VERY
LIGHT QPF EXPECTED FROM THE WAA. HOWEVER...THAT SHOULD CHANGE THIS
AFTN AS THE INDIRECT CIRCULATION OF THE UPPER JET MOVES OVER NORCAL
AND INCREASES UVVS AS THE GOA TROF MOVES TOWARDS THE W COAST. THE
ASSOCIATED OFFSHORE COLD FRONT AHEAD OF THE CLOSED LOW IS FORECAST
TO MOVE INLAND BY 00Z...THEN EWD INTO THE SIERNEV SHORTLY
THEREAFTER...AND THEN LINGER OVER THE AREA THROUGH 12Z SUN. PW PLUME
ASSOCIATED WITH THIS SYSTEM IS RELATIVELY MEAGER AND NARROW...ONLY
.60 TO .70 INCHES IN THE AMSU IMAGERY...BUT THE SYSTEM HAS STRONG
BAROCLINICITY AND GOOD JET SUPPORT. THUS THE WAA PRECIP IS MEAGER...
BUT PCPN RATES SHOULD INCREASE SUBSTANTIALLY ALONG THE COLD FRONT
AND IN THE COLD UNSTABLE AIR AFTER FROPA...ESPECIALLY FOR THE
SIERNEV INTO SUN MORNING. WE ARE LEANING TOWARD THE NAM TIMING AND
QPF. THE BAROCLINICITY WITH THE COLD FRONT/UPPER LOW SUGGESTS A
STRONG PRESSURE GRADIENT WILL DEVELOP WITH FROPA...AND THE MODELS
ARE INDICATING ABOUT A 5-6 MBS RDD-SAC GRADIENT AND A 10-11 MBS
MFR-SAC GRADIENT FROM LATE AFTN AND OVERNITE. 850-700 MBS FLOW
FORECAST TO INCREASE TO 40-50 KTS WITH FROPA AND WITH APPROACHING
UPPER TROF RESULTING IN NOT ONLY STRONG OROGRAPHICS FOR THE
SIERNEV...BUT ALSO STRONG SLY UPSLOPE FLOW FOR THE SHASTA DRAINAGE.
THESE FACTORS WILL AUGMENT PCPN AMOUNTS FOR THESE AREAS AND HAVE
UPGRADED WINTER STORM WATCH TO A WARNING. ALSO WITH THESE WINDS
ALOFT...AND INCREASING PRESSURE GRADIENTS...WINDS IN THE INTERIOR
VLY AND NERN FTHLS LIKELY TO REACH WIND ADVISORY CRITERIA WITH FROPA
MAINLY TONITE...BUT MAY BEGIN LATE THIS AFTERNOON IN THE NRN SAC
VLY. NAM/ETA BUFKIT FORECAST SOUNDINGS SHOW POTENTIAL FOR A BAND OF
40 KTS WINDS AT 2 TO 3 THOUSAND FEET TO MIX DOWN AROUND FROPA AND
HAVE ISSUED WIND ADVSRY FOR PORTIONS OF THE INTERIOR VLY.

WE EXPECT THE STEADY PCPN TO TURN TO SHOWERS FROM W TO E AFTER FROPA
ON SUN...AND AS SHORT WAVE ENERGY LIFTS NWD. LOOKS LIKE DYNAMICS
WEAKEN SUN NITE AND EARLY MON FOR A BREAK IN THE PCPN IN THE
INTERIOR VLY AS SHORT WAVE ENERGY DIGS THE UPPER TROF OFFSHORE.
HOWEVER....UPSLOPE FLOW AND LINGERING OROGRAPHICS CONTINUE TO
GENERATE A COUPLE OF TENTHS OF PCPN EVERY 3 HRS OR SO FOR THE
SIERNEV DURING THIS TIME. THEN ANOTHER...MORE SIGNIFICANT ROUND OF
PCPN IS EXPECTED MON NITE/TUE AS THE UPPER TROF DIGS OVER THE W
COAST SHIFTING A STRONG CYCLONIC UPPER JET SWD INTO CA. THE
DEEPENING TROF OVER WRN NOAM WILL ALLOW FOR ARCTIC AIR TO FLOW INTO
NORCAL BRINGING COLDER TEMPS...LOWER SNOW LEVELS AND MORE UNSETTLED
WX TO NORCAL INTO THE MIDDLE OF NEXT WEEK. THE PATTERN IS EXPECTED
TO MODERATE BY THE LATTER PART OF THE WEEK AND INTO NEXT WEEKEND.
