AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
410 AM PDT TUE NOV 1 2011

.DISCUSSION...
MODERATELY STRONG SHORT-WAVE TROUGH SLIDING SEWD ACROSS NE
CALIFORNIA EARLY THIS MORNING IS MARKING THE BEGINNING OF A TREND
TOWARD MORE ACTIVE WEATHER ACROSS NORCAL OVER THE NEXT WEEK. NORTH
WINDS WILL CONTINUE TO WORK THEY WAY SOUTHWARD ACROSS THE REGION
TODAY AS SUBSIDENCE AND COLD ADVECTION INCREASE IN THE WAKE OF
THIS WAVE. NORTHERLY SURFACE PRESSURE GRADIENTS ARE SHIFTING SOUTH
WITH THE MFR-SAC GRADIENT NOW BECOMING MORE BALANCED AS THE RDD-
SAC GRADIENT INCREASES. STILL LOOKS LIKE THE STRONGEST WINDS IN
THE VALLEY WILL FOCUS ALONG THE WEST SIDE OF THE SACRAMENTO
VALLEY...MAINLY ALONG AND WEST OF I-5 AND ARE LIKELY TO REMAIN A
LITTLE BELOW WIND ADVISORY CRITERIA ACROSS MOST OF THE REGION.
PRESSURE GRADIENTS BECOME MORE EASTERLY TONIGHT SHIFTING THE FOCUS
OF STRONGEST WINDS TO THE NORTHERN SIERRA RIDGETOPS AND WEST-
FACING CANYONS...THOUGH GUSTY WINDS WILL LIKELY CONTINUE OVER THE
WEST SIDE OF THE SACRAMENTO VALLEY INTO PORTIONS OF THE COAST
RANGE.

SHORT-WAVE RIDGING WEDNESDAY WILL QUICKLY BRING DIMINISHING WINDS
BEFORE THE PENDULUM SWINGS BACK TO MORE UNSETTLED WEATHER WITH THE
APPROACH OF THE DEEP UPPER TROUGH FROM THE GOA ON THURSDAY. THIS
NEXT SYSTEM PROMISES TO BRING SHOWERS TO MUCH OF THE REGION BY
THURSDAY AFTERNOON AND NIGHT...THOUGH QUICK MOVEMENT OF THE FRONT
AND NARROW MOISTURE TAP WILL LIKELY LIMIT PRECIP...ESPECIALLY IN
THE SACRAMENTO VALLEY WHERE MODELS CONTINUE TO INDICATE POTENTIAL
FOR SHADOWING ALONG THE WEST SIDE OF THE VALLEY. CONFIDENCE IS
HIGH IN PRECIPITATION FALLING OVER THE SIERRA WHERE SEVERAL INCHES
OF SNOW ARE POSSIBLE AT PASS LEVELS. TEMPERATURES WILL BE MUCH
COOLER WITH VALLEY SITES STRUGGLING TO REACH 60 DEGREES.

UNSETTLE PATTERN CONTINUES INTO THE WEEKEND WITH ANOTHER COLD WAVE
FORECAST TO MOVE THROUGH SATURDAY NIGHT INTO SUNDAY.

&&

.AVIATION...
PRIMARY AVN CONCERN WILL BE MDT TO STG NORTH/NORTHEAST WINDS TODAY.
SFC WINDS ARE ALREADY SUSTAINED 12-20 KTS WITH GUSTS UP TO 30 KTS
IN THE KRDD-KRBL VCNTY. EXPECT A PERIOD OF LLWS ACROSS THE CENTRAL
AND SRN SAC VLY EARLY THIS MORNING UNTIL SFC WINDS PICK UP. KDAX
RADAR IS SHOWING WIND SPEEDS NEAR 1500-2000 FT AROUND 35-45 KTS
WHILE SFC WINDS AT KSMF-KSAC-KMHR ARE CURRENTLY 8-15 KTS.
SUSTAINED WINDS WILL INCREASE AS THE MORNING PROGRESSES AND LLWS
SHOULD NO LONGER BE A CONCERN BY 16Z.

PEAK WINDS TODAY SHOULD OCCUR BETWEEN 18-01Z WITH TAF SITES HAVING
SUSTAINED WINDS 15-25 KTS WITH GUSTS UP TO 40 KTS. STRONGEST WINDS
SHOULD BE FROM REDDING SOUTHWARD TO SACRAMENTO AND TO THE WEST OF
INTERSTATE 5. STRONG NORTHEAST-EAST DOWNSLOPE WINDS WITH SIMILAR
SPEEDS ARE EXPECTED ALONG THE WESTERN SIERRA SLOPES. A LOCAL
AIRPORT ADVISORY HAS BEEN ISSUED FOR KRDD IN EFFECT UNTIL 01Z.

VFR CONDS PERSIST FOR TAF SITES AND MUCH OF THE REGION. HOWEVER...
THERE MAY BE SOME PATCHY FOG DEVELOPMENT IN MOUNTAIN VLYS DURING
MORNING HOURS. JBB
