AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO CA
300 AM PST TUE MAR 22 2005
.DISCUSSION...THE DISTRICT IS GETTING A GOOD SOAKING WITH UP TO 3
INCHES OF RAIN SO FAR IN THE MTNS OF THE N BAY...AND THE SANTA CRUZ
MTNS WILL WIND UP WITH THAT MUCH BY THIS AFTN. RIVERS AND STREAMS
HAVE RISEN CONSIDERABLY BUT STARTED LOW SO WE SHOULDNT SEE ANY
MAJOR FLOODING...BUT ISSUED URBAN/SMALL STREAM FLOOD ADVISORIES
FOR THE N BAY...WHERE FLOODED HIGHWAYS WERE REPORTED...AND FOR
SANTA CRUZ COUNTY. NO REPORTS OF PROBLEMS HAVE BEEN RECEIVED FROM
THERE BUT WITH PROLONGED MODERATE TO HEAVY RAIN THERES BOUND TO BE
SOME MINOR FLOODING. THE ADVISORIES EXPIRE AT 4 AM AND MAY NEED TO
BE EXTENDED...WILL MAKE THAT DECISION AFTER 3.
THE N BAY MAY BE OUT OF THE WOODS BY THEN. WIND SHIFTS ARE STARTING
TO SHOW UP AT THE BUOYS...MEANING THE COLD FRONT IS PASSING. WITH
THE SHIFT THE WINDS ARE DECREASING. THIS INDICATES THAT THE ONGOING
WIND ADVISORY CAN PROBABLY BE ALLOWED TO EXPIRE AT 4 AM AS THE FRONT
SHOULD BE INLAND BY THAT TIME. SANTA ROSA HAS ALREADY HAD A WIND
SHIFT...AT ABOUT 130 AM. THE RAIN SHOULD DECREASE ACROSS THE
DISTRICT FROM NW TO SE THIS MRNG...BY 2 AM THIS PROCESS APPEARED TO
BE BEGINNING IN THE N BAY...AND THE HEAVIEST RAIN HAD SHIFTED TO THE
SANTA LUCIAS AND THE ERN HALF OF SANTA CRUZ COUNTY.
WITH A MOIST AND SOMEWHAT UNSTABLE AIRMASS AND CONTINUING ONSHORE
FLOW...SHOWERS SHOULD BE NUMEROUS OVER THE DISTRICT TDA. WITH
COLDER AIR ALOFT WE CANT RULE OUT A FEW TSTMS...WE GET TSTMS WITH
MOST RAIN EVENTS IN SPRING. THE GFS HAS THE MOST UNSTABLE AIR OVER
OUR DISTRICT THIS MRNG WITH STABILIZATION INCREASING THIS AFTN AS
THE UPPER TROF ASSOCIATED WITH THE STORM MOVES SEWD.
UNSETTLED WX SHOULD CONTINUE FOR AWHILE. THE MODELS SET UP A CUTOFF
LOW OVER THE PACIFIC NW TDA AND LEAVE IT IN PLACE THRU FRI...WITH A
CYCLONIC NWLY FLOW ALOFT OVER OUR DISTRICT. THIS WILL LEAVE US IN A
PARTLY CLOUDY...SHOWERY WX REGIME. HOWEVER...THE FIRST TRAILING
SHORTWAVE CENTERED NEAR 35/134 IS HEADING SEWD AND WILL MOSTLY MISS
OUR REGION TO THE S. THIS IS THE WED SYSTEM THAT THE GFS IN
PREVIOUS DAYS OCCASIONALLY TRIED TO BRING INTO THE SRN PART OF OUR
DISTRICT WHILE THE EURO CONSISTENTLY TOOK IT S OF US. SCORE ONE FOR
THE EURO...THE GFS HAS NOW GOTTEN ON BOARD WITH THE OTHER MODEL.
BY THE WEEKEND AN UPPER RIDGE IS FINALLY FORECAST TO MOVE OVER OUR
DISTRICT BUT IT WILL PROBABLY BE DIRTY WITH AT LEAST SOME CLOUDS
MOVING OVER THE TOP AND THEN INTO OUR DISTRICT. ANOTHER
SIGNIFICANT CHANCE FOR RAIN APPEARS TO BE SUN NIGHT INTO MON WHEN
THE EURO AND GFS BOTH BRING AN UPPER TROF THRU THE RIDGE ACROSS OUR
DISTRICT. THE UNSETTLED WX PATTERN SHOWS NO SIGN OF ENDING WITH
MORE SHORTWAVES IN THE PIPELINE AFTER THAT.
