AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
956 AM PST THU FEB 25 2016

.SYNOPSIS...DRY WEATHER CONDITIONS AND UNSEASONABLY WARM
TEMPERATURES WILL CONTINUE THROUGH THE REMAINDER OF THE WORK WEEK
AS HIGH PRESSURE REMAINS OVER THE AREA. A WEAK SYSTEM PASSING TO
THE NORTH WILL BRING A CHANCE OF LIGHT PRECIPITATION OVER THE
NORTH BAY LATE FRIDAY. OTHERWISE...DRY WEATHER AND ABOVE AVERAGE
TEMPERATURES ARE LIKELY TO PERSIST INTO THE FIRST HALF OF NEXT WEEK.

&&

.DISCUSSION...AS OF 08:36 AM PST THURSDAY...CLOSELY WATCHING A
FOG BANK OFF THE SAN MATEO COAST INCHING TOWARD THE COAST...BUT
EASTWARD MOVEMENT SEEMS SLOW. DO NOT THINK THERE WILL BE MUCH
IMPACT FROM THIS FOG BANK. OTHERWISE...CLEAR SKIES PREVAIL ACROSS
THE BAY AREA. THE CLEAR SKIES LED TO A RATHER COOL START TO THE
DAY AWAY FROM URBAN CENTERS. MANY INTERIOR LOCATIONS WERE IN THE
30S AND 40S THIS MORNING. NO UPDATE IS PLANNED TO THE FORECAST AT
THIS TIME.

FOR THE REST OF THE DAY...A FEW HIGH CLOUDS WILL SPREAD OVER THE
REGION FROM THE NORTH. DESPITE THE INCREASING CLOUDS...IT SHOULD
BE ANOTHER MILD DAY WITH TEMPS IN THE 60S AND 70S...OR ABOUT 5 TO
15 ABOVE NORMAL.

&&

.PREV DISCUSSION...AS OF 2:45 AM PST THURSDAY...SATELLITE IMAGERY AND
SURFACE OBSERVATIONS SHOW MOSTLY CLEAR SKIES ACROSS THE DISTRICT
AT THIS TIME. TEMPERATURE/DEW POINT SPREADS ARE STARTING TO NARROW
ACROSS PORTIONS OF THE NORTH BAY SO SOME PATCHY FOG IS POSSIBLE
TOWARDS SUNRISE...MAINLY IN THE VALLEYS. OTHERWISE...HIGH PRESSURE
ALOFT WILL PROVIDE ANOTHER SUNNY AND WARM DAY ACROSS THE DISTRICT
WITH HIGH TEMPERATURES EXPECTED IN THE 60S AND 70S.

ON FRIDAY...AN UPPER LEVEL DISTURBANCE IS FORECAST TO APPROACH
THE WEST COAST. THE TAIL END OF THIS SYSTEM IS PROGGED TO MOVE
ACROSS NORTHERN CALIFORNIA LATE FRIDAY AND FRIDAY NIGHT BRINGING
COOLER TEMPERATURES AND RAIN CHANCES TO MAINLY THE NORTH
BAY...BUT ALSO POSSIBLY ACROSS AREAS NORTH OF SANTA CRUZ COUNTY.
HAVE LEFT POPS AS IS WITH THE GREATEST CHANCES ACROSS NORTHERN
SONOMA AND NAPA COUNTIES. RAINFALL AMOUNTS ARE FORECAST TO BE
UNDER A QUARTER OF AN INCH.

HIGH PRESSURE ALOFT WILL THEN BRIEFLY REBUILD OVER THE WEST ON
SATURDAY AND SUNDAY...WITH ANOTHER WEAK SYSTEM MOVING ACROSS THE
AREA SUNDAY NIGHT. THIS SYSTEM IS EXPECTED TO HAVE LESS OF AN
IMPACT ON THE DISTRICT THAN THE FIRST ONE WITH RAIN CHANCES BEING
LIMITED TO THE FAR NORTHERN PORTIONS OF THE NORTH BAY.

HIGH PRESSURE WILL THEN KEEP THE STATE DRY UNTIL MIDWEEK WHEN
ANOTHER TROUGH COULD BRING BETTER CHANCES OF RAIN TO NORTHERN
CALIFORNIA LATE THURSDAY INTO FRIDAY OF NEXT WEEK. THIS MAINLY
FALLS MAINLY OUTSIDE OF THE FORECAST TIME FRAME...BUT STILL
SOMETHING TO KEEP AN EYE ON.

&&

.AVIATION...AS OF 9:55 AM PST THURSDAY...MINOR OFFSHORE FLOW WILL
LEAD TO VFR CONDITIONS WITH WINDS MOSTLY UNDER 12KT THROUGH THE
DAY. MODELS INDICATE POTENTIAL FOR LOW CIGS TO FORM STARTING AFTER
10Z FOR MOST TERMINALS. FOR NOW WILL GO WITH BKN010 FOR MOST
LOCATIONS TO HIGHLIGHT THE POSSIBILITY WITH TYPICAL LOWER CIGS AND
VIS AT KSTS. HIGH CONFIDENCE THROUGH 08Z. MODERATE CONFIDENCE
AFTER THAT.

VICINITY OF KSFO...VFR CONDITIONS ARE EXPECTED TO PERSIST THROUGH
AT LEAST 10Z. IFR CIGS WILL BE POSSIBLE AROUND 12Z ALTHOUGH
CONFIDENCE IS NOT HIGH THAT IT WILL ACTUALLY MATERIALIZE. FOR NOW
WILL GO WITH BKN020 TO 16Z. GENERALLY LIGHT WINDS ARE EXPECTED
THIS MORNING WITH THE AFTERNOON SEA BREEZE REACHING 10 KTS.
CONFIDENCE IS HIGH THROUGH 10Z. MODERATE CONFIDENCE AFTER THAT.

SFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...SIMILAR TO KSFO VFR THROUGH THE DAY
WITH POTENTIAL FOR MVFR/IFR CONDITIONS AROUND OR JUST AFTER 10Z.
SHOULD RETURN TO VFR BY 16Z. CONFIDENCE IS HIGH THROUGH 08Z.
MODERATE CONFIDENCE AFTER THAT.

&&

.BEACHES...AS OF 9:55 AM PST THURSDAY...AN ENERGETIC LONG PERIOD
WESTERLY SWELL IS EXPECTED TO RETURN ON FRIDAY...WITH LONG PERIOD
FORERUNNERS ARRIVING FRIDAY MORNING. THESE SMALLER WAVES...4 TO 6
FEET OF 20 TO 22 SECONDS...WILL BE CAPABLE OF PRODUCING STRONG
RIP CURRENTS AND ALSO THE POTENTIAL FOR WASHING FISHERMEN FROM
JETTIES. THIS ENERGETIC SWELL IS EXPECTED TO BUILD ON FRIDAY
REACHING 10 TO 11 FEET AT 18 TO 20 SECONDS WITH A SMALLER LOCAL
SWELL OF 6 TO 7 FEET AT 13 SECONDS MIXING IN. THESE SEA CONDITIONS
ARE ANTICIPATED TO PERSIST THROUGH AT LEAST SATURDAY PRODUCING
LARGE BREAKING WAVES AT DEEP WATER BREAKS AND ASSOCIATED STRONG
RIP CURRENTS AND THE POTENTIAL FOR WAVES WASHING UNSUSPECTING
BEACH VISITORS INTO THE SEA.

&&
