KEY MESSAGES
UPDATED AT 124 PM PST WED NOV 26 2025
- DRY AND MILD CONDITIONS CONTINUE THROUGH THURSDAY
- COOLER TEMPERATURES FRIDAY AND INTO THE WEEKEND AS THE NEXT
SYSTEM APPROACHES
SHORT TERM
ISSUED AT 124 PM PST WED NOV 26 2025
(THIS EVENING THROUGH THURSDAY)
SEEING LESS CLOUD COVER COMPARED TO YESTERDAY AT THIS HOUR. THUS, A
GREATER POTENTIAL TO REACH OUR HIGH TEMPERATURES THIS AFTERNOON.
TEMPERATURES WILL WARM INTO THE LOWER 70S ACROSS THE CENTRAL COAST
AND SANTA CRUZ AREA, APPROACH 70 DEGREES F IN THE NORTH BAY, AND 60S
ACROSS MUCH OF THE REMAINDER OF THE REGION. THIS IS AS MODERATE, DRY
OFFSHORE FLOW PERSIST IN THE HIGHER ELEVATIONS AND A MID/UPPER LEVEL
RIDGE AXIS IS CURRENTLY IN PLACE ALOFT.
TONIGHT, AGAIN EXPECTING LESS WIDESPREAD COVERAGE OF LOW CLOUDS AND
FOG. HOWEVER, CANNOT RULE OUT PATCHY TO AREAS OF DENSE FOG ACROSS
THE NORTH BAY VALLEYS, EAST BAY VALLEYS, AND THE SANTA CLARA VALLEY
OVERNIGHT. TEMPERATURES OVERNIGHT ARE FORECAST TO BE MOSTLY IN THE
UPPER 30S TO LOWER 40S. IN THE HIGHER ELEVATIONS, WE CAN EXPECT
TEMPERATURES TO BE IN THE MID 50S TO LOWER 60S DUE TO CONTINUED
OFFSHORE WINDS.
ANY LOW CLOUDS AND/OR FOG THAT DOES DEVELOP WILL GIVE WAY TO MOSTLY
SUNNY SKIES BY THURSDAY AFTERNOON. THIS WILL AGAIN ALLOW TEMPERATURES
TO BE UP TO 10 DEGREES ABOVE SEASONAL AVERAGES. OVERALL, WITHIN A
FEW DEGREES OF WHAT TODAY'S FORECAST HIGH TEMPERATURES WILL BE.
LONG TERM
ISSUED AT 124 PM PST WED NOV 26 2025
(THURSDAY NIGHT THROUGH NEXT TUESDAY)
THURSDAY NIGHT AND INTO FRIDAY AN UPPER LEVEL TROUGH IS FORECAST TO
MOVE INTO THE PACIFIC NORTHWEST. THIS WILL BRING A WEAK, DRY FRONTAL
BOUNDARY ACROSS THE BAY AREA AND CENTRAL COAST COOLING TEMPERATURES
TO NEAR SEASONAL AVERAGES. A GENERAL TROUGHING PATTERN WILL PERSIST
OVER THE REGION THROUGH EARLY NEXT WEEK AS HIGH PRESSURE BUILDS
OFFSHORE. THUS, LOOK FOR WEAK TO MODERATE OFFSHORE FLOW IN THE
HIGHER ELEVATIONS, DRY CONDITIONS, AND TEMPERATURES NEAR SEASONAL
AVERAGES.
AVIATION
(00Z TAFS)
ISSUED AT 355 PM PST WED NOV 26 2025
CURRENTLY VFR ACROSS THE REGION WITH LOCALIZED FOG RETURNING TO THE
NORTH AND EAST BAYS TONIGHT. MODERATE CONFIDENCE THAT FOG COVER WILL
CONTINUE TO DIMINISH TONIGHT AS OFFSHORE WINDS BRING DRIER AIR INTO
THE REGION. GUIDANCE DOES SHOW SOME POTENTIAL FOR VISIBILITIES TO
DROP INTO MVFR TERRITORY ACROSS THE REST OF THE BAY AREA BUT
CONFIDENCE IS LOW THAT WIDESPREAD FOG WILL DEVELOP. MAIN ADJUSTMENT
WAS TO ADD A TEMPO FOR LOWERED VISIBILITIES TO SJC EARLY TOMORROW
MORNING. OTHERWISE, WINDS GENERALLY STAY LIGHT AND OFFSHORE THROUGH
THE TAF PERIOD WITH BREEZIER WINDS DEVELOPING DURING THE
AFTERNOON/EVENING HOURS.
VICINITY OF SFO...VFR WITH SOME POTENTIAL FOR MVFR CONDITIONS
OVERNIGHT. FOG IS NOT EXPECTED TO IMPACT THE TERMINAL BUT
VISIBILITIES MAY DROP BELOW 6SM BETWEEN 10Z-16Z. WINDS REMAIN LIGHT
AND OFFSHORE OVERNIGHT WITH MODERATE ONSHORE WINDS REDEVELOPING
DURING THE DAY.
SFO BRIDGE APPROACH...SIMILAR TO SFO.
MONTEREY BAY TERMINALS...VFR THROUGH THE TAF PERIOD. WINDS REMAIN
OFFSHORE WITH LIGHT WINDS AT MRY AND LIGHT TO MODERATE AT SNS.
DRAINAGE WINDS ARE EXPECTED TO DEVELOP AT SNS EARLY TOMORROW MORNING
AND PERSIST THROUGH THE EARLY AFTERNOON.
MARINE
(TONIGHT THROUGH NEXT MONDAY)
ISSUED AT 355 PM PST WED NOV 26 2025
LINGERING HIGH PRESSURE ALONG THE COAST WILL KEEP GENTLE TO
MODERATE NORTHERLY FLOW OVER THE COASTAL WATERS THROUGH TONIGHT.
PATCHY DENSE FOG WILL BE POSSIBLE AGAIN TONIGHT, ESPECIALLY IN THE
WEST DELTA. A WEAK DISSIPATING COLD FRONT WILL BRING INCREASING
NORTHERLY WINDS THANKSGIVING DAY LASTING INTO FRIDAY.
ADDITIONALLY, A SQUARED SEAS STATE WILL DEVELOP LATE THANKSGIVING
DAY LEADING TO HAZARDOUS CONDITIONS.
