AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
830 PM PST THU NOV 13 2008

.DISCUSSION...WATER VAPOR IMAGERY SHOWS A LARGE RIDGE OF HIGH
PRESSURE AMPLIFIED OVER THE PACIFIC...WITH DRY NORTHWESTERLY FLOW
FILTERING ACROSS NORTHERN CALIFORNIA.  AS A RESULT...TEMPERATURES
WARMED SIGNIFICANTLY ACROSS THE REGION TODAY...WITH TEMPERATURES
AVERAGING 10 TO 15 DEGREES ABOVE NORMAL.  IN FACT...MODESTO TIED ITS
PREVIOUS RECORD...WITH 77 DEGREES TODAY.  CURRENTLY...TEMPERATURES
ARE RUNNING BETWEEN 3 AND 16 DEGREES WARMER THAN THIS TIME LAST
NIGHT...RESULTING IN A VERY PLEASANT AND MILD EVENING.  THIS IS IN
PART DUE TO A BIT OF A NORTHERLY BREEZY ACROSS THE REGION THIS
EVENING...WITH THE KDAX VAD SHOWING SOME 45 KNOTS WINDS AT 2000
FEET.  AT TIME TIME...THESE STRONGER WINDS ARE NOT MIXING DOWN TO
THE SURFACE.  HOWEVER...AS THE MEDFORD GRADIENT INCREASES TONIGHT
FROM AROUND 9.6 MILLIBARS TO SOMEWHERE BETWEEN 12 AND 13 MILLIBARS
TOMORROW MORNING...SOME OF THESE STRONGER WINDS MAY MAKE IT DOWN TO
THE SURFACE...CREATING SOME LOCALLY GUSTY CONDITIONS.  HOWEVER...NOT
EXPECTING THESE LOCALLY GUSTY CONDITIONS TO BE WIDESPREAD ENOUGH TO
WARRANT A WIND ADVISORY AT THIS TIME.

THE WINDS WILL MAKE TOMORROW TEMPERATURES FORECAST AN INTERESTING
ONE.  AT THIS TIME...MODELS ARE WARMING 850 TEMPERATURES BETWEEN 4
AND 5 DEGREES TOMORROW OVER TODAY...AND THE 00Z OAKLAND SOUNDING
SHOWED A SIMILAR WARMING AT 925 MB.  THIS WOULD EQUATE TO A SIMILAR
WARMING AT THE SURFACE HERE IN THE VALLEY.  HOWEVER...IF THE WINDS
ARE A LITTLE STRONGER THAN CURRENTLY FORECASTED THEN TEMPERATURES
MAY NOT WARM QUITE AS MUCH.  HOWEVER...WILL SEND AN UPDATE THIS
EVENING TRENDING TEMPERATURES FOR TOMORROW UPWARD AND FLIRTING WITH
RECORDS IN MANY LOCATIONS.  PALMER

&&

.AVIATION...HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE REGION
DURING THE NEXT 24 HOURS...WITH VFR CONDITIONS PREVAILING.  A
NORTHERLY GRADIENT WILL ALSO STRENGTHEN OVERNIGHT TONIGHT...HELPING

THE VALLEY AND UP TO 40 KT POSSIBLE OVER THE SIERRA...PARTICULARLY
DURING THE DAYTIME FRIDAY.
