AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
900 AM PST SUN JAN 11 2009

.DISCUSSION...
DENSE FOG HAS DEVELOPED THIS MORNING OVER PORTIONS OF THE SAN
JOAQUIN AND SOUTHERN SACRAMENTO VALLEYS AND DELTA ALONG THE CENTRAL
PORTIONS OF THE VALLEY AND NEAR WATERWAYS. AS A RESULT OF THE
MORNING FOG I WOULD EXPECT STOCKTON AND MODESTO IN THE
SAN JOAQUIN VALLEY TO STRUGGLE TO GET TO 60 TODAY AND MORE THAN
LIKELY SACRAMENTO ONLY WARMING INTO THE LOWER TO MID 60S. THEREFORE
I DONT EXPECT ANY RECORD HIGH TEMPERATURES TO BE BROKEN TODAY FOR
THOSE AREAS.

PLACES TO WATCH FOR NEAR RECORDS OR RECORDS TODAY WOULD BE
BLUE CANYON...GRASS VALLEY...PARADISE...REDDING AND RED BLUFF.

A STRENGTHEN PRESSURE GRADIENT LATER TODAY AND TONIGHT WILL
INCREASE SURFACE WINDS. AT FIRST THE MOUNTAINS AND FOOTHILLS WILL
GET GUSTY WINDS THIS EVENING AND OVERNIGHT AND THEN ON MONDAY IN THE
CENTRAL VALLEY...ALTHOUGH OVER THE FAR WESTERN PORTIONS OF THE
CENTRAL VALLEY SOME LOCAL GUSTY WINDS MAY OCCUR OVERNIGHT. ENOUGH
SURFACE MIXING SHOULD OCCUR IN THE VALLEY OVERNIGHT TO KEEP MOST
TEMPERATURES ABOVE FREEZING...BUT A FEW WIND SHELTERED LOCATIONS MAY
BE ABLE TO DIP DOWN TO AROUND FREEZING.

WINDS MAY COME CLOSE TO WIND ADVISORY CRITERIA TONIGHT AND MONDAY
MORNING ALONG THE COASTAL RANGE...SIERRA NEVADA AND SOME FOOTHILL
LOCATIONS DUE TO THE GUSTY WINDS.  WE WILL HAVE TO EXAMINE
CONDITIONS AND MODELS TO DETERMINE WHETHER OF NOT TO ISSUE ADVISORY
WITH AFTERNOON PACKAGE. SOME FOG WILL LIKELY FORM AGAIN TONIGHT IN
THE SAN JOAQUIN VALLEY. WHETHER OR NOT PATCHES OF FOG FORM AROUND
SACRAMENTO WILL DEPEND ON THE AMOUNT OF MIXING NEAR THE SURFACE.

&&

.AVIATION...
GENERALLY VFR CONDITIONS THROUGH MONDAY WITH HIGH PRESSURE REMAINING
OVER THE AREA. ALTHOUGH AREAS OF IFR TO LIFR FOG AND LOW CLOUDS IN
THE CENTRAL VALLEY SOUTH OF KMYV HAVE DEVELOPED THIS MORNING AND
SHOULD DISSIPATE AROUND NOON FOR MVFR/VFR CONDITIONS IN THE
AFTERNOON. THE NORTHERLY SURFACE PRESSURE GRADIENT WILL STRENGTHEN
TODAY AND TONIGHT BRINGING GUSTY WINDS UP TO 35 KT IN THE SACRAMENTO
VALLEY NORTH OF KMYV WITH THE STRONGEST WINDS ALONG THE WEST SIDE OF
THE VALLEY. NORTHEASTERLY WIND GUSTS UP TO 40 KT ARE EXPECTED
THROUGH NORTHEAST-SOUTHWEST ORIENTED CANYONS AND OVER THE RIDGES
TONIGHT INTO MONDAY.  THE NORTHERLY WINDS ARE EXPECTED TO KEEP THE
FOG FROM FORMING MOST PLACES TONIGHT AND MONDAY MORNING BUT PATCHY
FOG MAY FORM ALONG THE EAST SIDE OF THE VALLEY SOUTH OF INTERSTATE
80 AROUND SUNRISE.

&&

.STO WATCHES/WARNINGS/ADVISORIES...
.DENSE FOG ADVISORY UNTIL 11 AM THIS MORNING FOR THE SOUTHERN
SACRAMENTO AND NORTHERN SAN JOAQUIN VALLEYS INCLUDING THE DELTA.
