AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1032 AM PDT WED JUN 19 2013
.DISCUSSION...AS OF 08:35 AM PDT WEDNESDAY...THE UPPER LEVEL TROUGH
THAT MOVED ACROSS NORTHERN CALIFORNIA YESTERDAY SUCCESSFULLY CLEARED
OUT THE MARINE LAYER OVERNIGHT. THIS MORNING THE SKIES ARE MOSTLY
CLEAR WITH COOLER MORNING TEMPERATURES. WENT AHEAD AND DID A QUICK
FORECAST UPDATE TO REMOVE CLOUDS AND FOG FROM THE FIRST PERIOD FORECAST.
EXPECTING SLIGHTLY WARMER TEMPERATURES TODAY UNDER SUNNY SKIES.
A WEAK UPPER LEVEL RIDGE IS FORECAST TO BUILD IN OVER THE WEST
DURING THE NEXT FEW DAYS. THIS WILL ALLOW A GRADUAL WARMING TREND
THAT WILL LAST INTO THE WEEKEND. BY SATURDAY HIGHS ARE EXPECTED
TO WARM INTO THE 60S AND 70S COAST SIDE...80S AROUND THE BAY WITH
LOWER TO MID 90S POSSIBLE IN THE WARMEST INTERIOR LOCATIONS.
TEMPERATURES ARE PROGGED TO COOL OFF BEGINNING ON SUNDAY AS AN
UPPER TROUGH RE-ESTABLISHES ALONG THE COAST. LAST NIGHT'S RUN OF
THE ECMWF EVEN BRINGS PRECIPITATION TO NORTHERN CALIFORNIA INCLUDING THE
NORTHERN PORTIONS OF OUR CWA BY MONDAY AND TUESDAY. THIS WOULD BE
NICE IF IT VERIFIES...BUT WILL WAIT A FEW MORE MODEL RUNS BEFORE
COMPLETELY BUYING INTO THIS SCENARIO.
SUMMER BEGINS AT 05:04Z ON JUNE 21ST...OR 10:04 PM PDT JUNE 20TH.
