AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
953 AM PDT TUE OCT 25 2011

.UPDATE DISCUSSION...
SATELLITE IMAGERY REVEALS SOME LOW STRATUS OVER MUCH OF SAC
COUNTY THIS MORNING AND BEGINNING TO ERODE FROM THE EDGES, AS IS
THE CASE WITH THE COASTAL STRATUS. THE BREEZY NORTH WINDS HAVE
BEGUN ACROSS THE NORTH AND WILL SPREAD SOUTHWARD TODAY. THIS IS
NOT A HUGE EVENT, BUT THIS IS AS STRONG AS WE HAVE SEEN IN AWHILE.
IT APPEARS THE STRONGEST WIND WILL BE TODAY DOWN THE CENTRAL
VALLEY AND TONIGHT DOWN THE WEST SLOPE OF THE SIERRA, ESPECIALLY
OVER EXPOSED RIDGES AND THROUGH WIND ALIGNED CANYONS LIKE THE
FEATHER RIVER CANYON. EVEN THOUGH COLD AIR ADVECTION AND LOWER
UPPER HEIGHTS WILL RESULT IN LOWER TEMPS TODAY, THE WARMING
DOWNSLOPE WINDS ACROSS THE FOOTHILLS AND CENTRAL VALLEY WILL
COUNTER SOME OF THAT COOLING. WED WILL BE SIMILAR IN TEMPS WITH A
LITTLE LESS WIND IN THE VALLEY. JCLAPP

.EXTENDED DISCUSSION (SATURDAY THROUGH TUESDAY)
WEAK RIDGING QUICKLY SHIFTS EASTWARD BY FRIDAY AS A GULF OF
ALASKA TROUGH MOVES THROUGH THE PACIFIC NORTHWEST. MOST OF THE
PRECIPITATION WITH THIS STORM IS EXPECTED TO REMAIN NORTH OF OUR
FORECAST AREA. MODELS DIFFERENTIATE FROM SUNDAY ONWARD. THE ECMWF
KEEPS FAIRLY STRONG ANTICYCLONIC FLOW OVER THE REGION INTO EARLY
NEXT WEEK...ALLOWING FOR A STRETCH OF WARMER THAN NORMAL WEATHER.
THE GFS BRINGS ANOTHER SHORTWAVE INTO THE PACIFIC NORTHWEST
MONDAY...AND IS GENERALLY A COOLER SOLUTION. FAVOR THE ECMWF
HERE...AND AS SUCH THE FORECAST REFLECTS A GRADUAL WARMING IN THE
EXTENDED PERIOD. DANG

&&

.AVIATION...
VFR CONDS WILL PREVAIL AGAIN TODAY AFTER SOME LINGERING MORNING
MVFR/IFR CIG/VIS THROUGH 17-18Z FOR SRN SAC VLY AND NRN SAN
JOAQUIN VLY. THE INCREASING NORTH WIND DOWN THE VALLEY MAY PUSH
SOME OF THE STRATUS INTO THE LOWER MOTHER LODE FOOTHILLS OF
AMADOR AND CALAVERAS COUNTIES THIS MORN.

MAIN AVN CONCERN TODAY WILL BE THE INCREASING N-NE WINDS.
BREEZY CONDS SHOULD REMAIN NEAR THE REDDING TO WILLOWS WITH
MODERATE GUSTS AT 15-20 KTS THIS MORNING AND EXPANDING TOWARD
KVCB THIS AFTN. MODERATE TO LOCALLY STRONG N-NE WINDS EXPECTED
ACROSS PORTIONS OF LAKE COUNTY TERRAIN. THE WINDS ALONG THE WRN
SIERRA SLOPES WILL STRENGTHEN LATER TONIGHT INTO WED WITH STRONG
DOWNSLOPE GUSTS THROUGH NE ALIGNED CANYONS. THERE IS ALSO A
SLIGHT CHANCE OF RAIN IN THE NORTHERN SIERRA AND MTNS OF WRN
PLUMAS COUNTY THIS AFTN.   JCLAPP
