AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SACRAMENTO CA 1010 PM PST FRI NOV 23 2007 .DISCUSSION... NO CHANGES TO CURRENT FORECASTS. HIGH PRESSURE WILL REMAIN OVER THE AREA BEFORE WEAKENING SUNDAY AS A WEAK WEATHER SYSTEM BRINGS AN INCREASE IN MAINLY HIGH CLOUDS. CLEAR SKIES OVERNIGHT WILL ALLOW THE SURFACE TO RADIATE EFFECTIVELY OVERNIGHT GIVEN THE DRY AIRMASS IN PLACE...AND AREAS OF FROST ARE ONCE AGAIN EXPECTED ACROSS THE CENTRAL VALLEY BY EARLY SATURDAY MORNING. LOCALLY GUSTY NORTHEAST WINDS HAVE ONCE AGAIN DEVELOPED OVER THE NORTHERN SIERRA THIS EVENING. THESE ARE EXPECTED TO DECREASE SATURDAY MORNING AS PRESSURE GRADIENTS RELAX. && .PREVIOUS DISCUSSION... BREEZY CONDITIONS THIS AFTERNOON ARE EXPECTED TO SUBSIDE IN THE VALLEY THIS EVENING WHILE IN THE MOUNTAINS THEY SHOULD INCREASE AGAIN THIS EVENING AS THE GRADIENT TIGHTENS ACROSS THE SIERRA.

HIGH PRESSURE OVER THE WEST COAST WILL CONTINUE THIS WEEKEND SO EXPECT COLD MORNINGS WITH HIGHS IN THE MID 60S FOR THE CENTRAL VALLEY.
