EVENT...UPDATE..SHOWERS ENHANCING OFF SAN LUIS OBISPO TO VENTURA COAST
.
SATELLITE ANALYSIS AND TRENDS...SINCE PREVIOUS SPENES MESSAGE FOR S
CA..SOME CHANGES HAVE BEEN TAKING PLACE. FIRST...BAND OF CNVTN OVER SAN
LUIS OBISPO COUNTY PERSISTS..BUT NEW CLOUD TOP ENHANCEMENT/COOLING HAS
BEEN OCCURRING SW OF SAN LUIS OBISPO/W OF SANTA BARBARA COASTS. THERE HAS
BEEN SOME EWD DRIFT OF THE BAND OVER THE PAST COUPLE OF HRS. WOULD EXPECT
AT LEAST SOME MOD SHOWERS TO MOVE INTO WRN SANTA BARBARA COUNTY OVER THE
NEXT COUPLE OF HRS. WOULD ALSO EXPECT CELL TRAINING TO CONTINUE OVER PARTS
OF SAN LUIS OBISPO COUNTY..AND THIS MAY ALSO BECOME AN ISSUE OVER WRN AND
SWRN SANTA BARBARA COUNTY AS WELL OVERNIGHT A BIT FURTHER SE..CLOUD TOPS
HAVE BEEN COOLING OVER ERN HALF OF SANTA BARBARA/SWRN VENTURA COUNTIES
AND SW OF THE COAST. ENHANCING SHOWERS EXTEND TO..AND S AND SW OF..SANTA
CRUZ ISLAND. THE CLOUD TOPS HERE ARE WARMER..SO WOULD ESTIMATE GENERALLY
LOWER RAINFALL RATES THUS FAR HERE THAN OVER SAN LUIS OBISPO.
.
WV IMAGERY ANIMATION SHOWS UPPR LOW/TROF OF THE CENTRAL CA COAST IS
BECOMING MORE SW-NE ORIENTED WITH TIME. ANIMATION SUGGESTS THAT SW PORTION
OF THE TROF WILL CONTINUE TO SWING/PIVOT TWD THE S CA COAST OVERNIGHT
AND DURING THE MORNING HRS..RESULTING IN INCRG LIFT AND UPPR DIFFLUENCE
IN GENERAL VCNTY OF SANTA BARBARA AND TO THE SW OFFSHORE. THUS..WOULD
EXPECT INCRG RAINFALL RATES AND AN EXTENDED PERIOD OF CELL TRAINING ACRS
THE AREA FM SAN LUIS OBISPO THRU VENTURA COUNTIES DURING THE OVERNIGHT
AND WEDNESDAY MORNING. EVENTUALLY..SOME MOD RAIN MAY SPREAD INTO SW/W
LOS ANGELES COUNTY AS TROF PROGRESSES FURTHER E.
.
DO NOT HAVE ANY LATER MICROWAVE PASSES SINCE PREVIOUS SPENES MESSAGE.. AND
EXTREME WARM TOP NATURE OF SHOWERS MAKES IT DIFFICULT TO DISCERN
QUANTITATIVE GOES-BASED RAINFALL ESTIMATES ATTM. BUT AGAIN..GENERAL STLT
TRENDS POINTS TOWARD INCREASINGLY HEAVIER RAINFALL WITH TIME.
