AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
855 PM PST WED FEB 17 2016

.SYNOPSIS...A FRONTAL SYSTEM WILL BRING MODERATE AMOUNTS OF RAIN
TO THE REGION THROUGH THIS EVENING...WITH BRIEF HEAVY RAIN AT
TIMES. RAIN WILL CHANGE TO SHOWERS AFTER MIDNIGHT. LOCALLY STRONG
AND GUSTY SOUTHWEST WINDS WILL CONTINUE OVERNIGHT...ESPECIALLY IN
THE HILLS. SHOWERS WILL CONTINUE INTO THURSDAY MORNING AND THEN
TAPER OFF THURSDAY AFTERNOON. A WEATHER SYSTEM WILL BRING
ADDITIONAL RAIN TO THE NORTHERN PART OF THE DISTRICT ON FRIDAY.
DRY WEATHER IS THEN EXPECTED FOR THE UPCOMING WEEKEND...ALONG WITH
WARMER TEMPERATURES.

&&

.DISCUSSION...AS OF 8:55 PM PST WEDNESDAY...A COLD FRONT
CURRENTLY EXTENDS FROM THE EAST BAY SSW ACROSS THE SANTA CLARA
VALLEY AND MONTEREY BAY AREA. THIS FRONT HAS BEEN PRODUCING
WIDESPREAD RAIN WITH BURSTS OF HEAVY RAIN RIGHT ALONG THE FRONTAL
BOUNDARY. ISOLATED LIGHTNING STRIKES HAVE ALSO BEEN DETECTED. RAIN
TOTALS THUS FAR ARE MOSTLY IN THE 0.25-0.75" RANGE...BUT A FEW
LOCATIONS IN THE COASTAL HILLS HAVE PICKED UP AROUND AN INCH.
RAINFALL HAS TAPERED OFF BEHIND THE FRONT...BUT EXPECT SHOWER
ACTIVITY TO INCREASE LATER TONIGHT INTO EARLY THURSDAY MORNING AS
THE COLD AND UNSTABLE POST-FRONTAL AIRMASS ARRIVES. IN
ADDITION...ISOLATED THUNDERSTORMS ARE POSSIBLE THROUGH THE NIGHT.

SOUTH WINDS BECOME STRONG AND GUSTY AHEAD OF THE FRONT THIS
AFTERNOON. WINDS HAVE SWITCHED TO THE SOUTHWEST BEHIND THE FRONT
AND HAVE REMAINED QUITE STRONG. STRONGEST WINDS ARE IN THE HILLS
WHERE WIND GUSTS ARE LOCALLY AS HIGH AS 55 MPH. BASED ON LATEST
MODEL GUIDANCE...SOUTHWEST WINDS WILL REMAIN LOCALLY STRONG AND
GUSTY THROUGH MUCH OF THE NIGHT. THE WIND ADVISORY FOR ELEVATIONS
ABOVE 1000 FEET IN THE HILLS HAS BEEN EXTENDED UNTIL 4 AM PST.
WINDS ARE FORECAST TO EASE BY LATE TONIGHT.

THE 00Z MODELS THAT ARE IN THUS FAR ARE CONSISTENT WITH PREVIOUS
MODEL RUNS IN TAPERING OFF SHOWER ACTIVITY ON THURSDAY
AFTERNOON...WITH MOST PRECIP FORECAST TO END BY THURSDAY EVENING.

THE NEXT SYSTEM IS FORECAST TO SPREAD RAIN ACROSS THE SAN
FRANCISCO BAY AREA ON FRIDAY. RAINFALL AMOUNTS ARE EXPECTED TO BE
MOSTLY LIGHT...BUT MODERATE AMOUNTS OF RAIN MAY FALL IN THE NORTH
BAY. THE 00Z NAM SHOWS LIGHT RAIN MAKING IT AS FAR SOUTH AS
MONTEREY BAY AND BIG SUR BY LATE FRIDAY AFTERNOON. SO WE MAY NEED
TO EXTEND RAIN CHANCES FARTHER SOUTH...AND INCREASE RAIN CHANCES
IN THE NORTH GIVEN THE DEGREE OF MODEL AGREEMENT.

DRY WEATHER IS FORECAST TO RETURN BY THE UPCOMING WEEKEND...ALONG
WITH WARMER TEMPS...AS AN UPPER RIDGE DEVELOPS OVER CALIFORNIA.
THE RIDGE IS THEN FORECAST TO STRENGTHEN EARLY NEXT WEEK...WHICH
WILL RESULT IN TEMPERATURES WARMING SEVERAL DEGREES ABOVE NORMAL
BY MONDAY AND TUESDAY.

&&

.AVIATION...AS OF 3:47 PM PST WEDNESDAY...THE CURRENT VISIBLE
SATELLITE IMAGE IS SHOWING A COLD FRONT APPROACH THE TERMINALS
THIS AFTERNOON. WINDS ARE INCREASING OUT OF THE SOUTH SOUTHEAST
AHEAD OF THE FRONT WHICH WILL BRING RAIN TO THE TERMINALS THIS
EVENING. FORECAST MODELS ARE SHOWING THE FRONTAL PASSAGE TO OCCUR
AROUND 0400Z FOR THE SAN FRANCISCO BAY AREA AND CLOSER TO 0700Z
FOR THE MONTEREY BAY AREA.

VICINITY OF KSFO...GUSTY SOUTHEASTERLY WINDS VFR CIGS ARE
EXPECTED TO BECOME MORE SOUTH SOUTHWESTERLY WITH CIGS BECOMING
MVFR BY AROUND 0200Z. MODERATE RAIN IS EXPECTED WITH FRONTAL
PASSAGE AROUND 0400Z. WINDS BEHIND THE FRONT WILL BECOME WEST
SOUTHWESTERLY BY AROUND 0530Z WITH LIGHT SHOWERS AND MVFR CIGS.

CONFIDENCE IS MODERATE.

SFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...SOUTHEASTERLY WINDS ARE EXPECTED TO
PREVAIL AFTERNOON INTO THE EVENING HOURS AHEAD OF THE APPROACHING
FRONT. LIGHT RAIN IS EXPECTED TO ARRIVE TO THE TERMINALS AROUND
