 AREA FORECAST DISCUSSION
 NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
 230 AM PST WED MAR 10 2010
 
 .DISCUSSION...AS OF 2:30 AM PST WEDNESDAY...A COLD FRONT MOVED
 THROUGH THE SAN FRANCISCO BAY AREA EARLY THIS MORNING PRODUCING
 LOCALLY HEAVY RAIN. STRONG AND GUSTY NORTHWEST WINDS
 FOLLOWED THE FRONT WITH SOME LOCATIONS STILL GUSTING TO 30 MPH.
 RAINFALL AMOUNTS IN THE POPULATED AREA HAVE BEEN MAINLY IN THE 1/10
 TO 1/4 INCH RANGE WITH HIGHER ELEVATIONS REPORTING AS MUCH AS 0.55
 INCH. THE FRONT WILL MOVE ACROSS MONTEREY AND SAN BENITO
 COUNTIES BEFORE SUNRISE...BUT WILL HAVE LOST SOME OF ITS POWER. LIGHT
 TO MODERATE RAIN WILL ACCOMPANY THE FRONT WITH GUSTY NORTHWEST WINDS
 TO FOLLOW.
 
 AS THE COLD AIR SETTLES OVER THE REGION THROUGH THIS MORNING...ENOUGH
 INSTABILITY MAY PRODUCE ISOLATED SHOWERS. THE SHOWERS WILL
 DECREASE FROM NORTH TO SOUTH THROUGH THE DAY. ALSO...THE AREA WILL
 EXPERIENCE ANOTHER COOL DAY WITH TEMPERATURES RISING TO SLIGHTLY
 HIGHER READINGS THAN YESTERDAY...BUT REMAINING BELOW SEASONAL
 NORMALS.
 
 ON THURSDAY WEAK RIDGING WILL PROVIDE A WARMER ATMOSPHERE ALLOWING
 AFTERNOON TEMPERATURES TO WARM TO NEAR NORMAL. HOWEVER...THE
 RIDGE WILL BE SHORT LIVED AS ANOTHER TROUGH APPROACHES THE COAST.
 RAIN IS EXPECTED TO BEGIN LATE THURSDAY NIGHT FOR PORTIONS OF THE
 NORTH BAY WITH THE BEST CHANCE FOR RAIN ACROSS THE ENTIRE AREA ON
 FRIDAY AND FRIDAY NIGHT. THIS DISTURBANCE MOVES THROUGH FAIRLY
 QUICKLY WITH RIDGING OVER CALIFORNIA BEGINNING ON SATURDAY AND
 CONTINUING INTO EARLY NEXT WEEK. AFTERNOON TEMPERATURES WILL RISE
 ABOVE SEASONAL NORMS ON SUNDAY...MONDAY AND IN THE SOUTHERN PORTION
 OF THE DISTRICT ON TUESDAY.
 
 FOR TUESDAY BOTH THE GFS AND ECMWF ARE IN GOOD AGREEMENT WITH
 BRINGING THE NEXT CHANCE FOR RAIN INTO CALIFORNIA. THE SAN FRANCISCO
 AND MONTEREY BAY AREAS WILL BE ON THE SOUTHERN FRINGE OF THIS SYSTEM
 SO AT THIS TIME WILL ADD A SLIGHT CHANCE FOR RAIN IN THE NORTH BAY.
