SHORT TERM
ISSUED AT 121 PM PST SAT JAN 24 2026
(THIS EVENING THROUGH SUNDAY)
GENERALLY FAIR WEATHER ACROSS THE BOARD TODAY. TEMPERATURES
THIS AFTERNOON ARE ABOUT 10-20 DEGREES WARMER THAN 24 HOURS AGO
THANKS TO TODAY'S LACK OF TULE FOG AND STRATUS. IN FACT, THE ONLY
CLOUD COVER VISIBLE ON SATELLITE IS A BIT OF STRATUS OFF THE COAST
OF BODEGA BAY AND SOME PATCH TERRAIN-INDUCED CU ALONG THE BIG SUR
COAST. TEMPERATURES ARE EXPECTED TO BE A BIT CHILLIER TONIGHT DUE
TO THE LACK OF CLOUD COVER. SUNDAY MORNING LOWS WILL RANGE FROM
THE MID-30S (INTERIOR) TO LOW 40S (COASTAL). THE ONLY OTHER
NOTABLE MENTION IN THE SHORT TERM IS THAT WE'LL HAVE ONE MORE
NIGHT OF BREEZY OFFSHORE WINDS ALONG INTERIOR RIDGETOPS BEFORE THE
LOW PRESSURE SYSTEM RESPONSIBLE (PART THE SAME ONE WREAKING HAVOC
ON THE CENTRAL AND EASTERN US CURRENTLY) MOVES OUT AND IS REPLACED
LARGELY BY ZONAL FLOW ALOFT. THIS WILL RELAX SURFACE PRESSURE
GRADIENTS AND CAUSE ANY OFFSHORE WINDS TO DIMINISH AND BECOME
LIGHT, OR EVEN LIGHT ONSHORE IN SOME LOCATIONS BY SUNDAY
AFTERNOON.
LONG TERM
ISSUED AT 121 PM PST SAT JAN 24 2026
(SUNDAY NIGHT THROUGH NEXT FRIDAY)
WITH MOSTLY BENIGN CONDITIONS THROUGH THE EARLY WEEK, WE'LL JUMP
TO SUNDAY WHEN A WEAK UPPER LEVEL SHORT WAVE TROUGH IS PROGGED TO
MOVE OVER THE REGION. THIS WILL BRING A SLIGHT CHANCE OF RAIN TO
THE AREA. HOWEVER, BASED ON THE MOST RECENT FORECAST UPDATES IT
SEEMS LIKE THIS MAY BE LIMITED TO COASTAL RANGES AS WELL AS THE
NORTH BAY. AMOUNTS ARE VERY SLIM AT A FEW HUNDREDTHS OF AN INCH
FOR MOST AND UP TO A TENTH OR TWO FROM THE GOLDEN GATE NORTHWARD.
BY NEXT FRIDAY, SOME MODEL GUIDANCE IS ADVERTISING ANOTHER CHANCE
FOR RAIN, BUT THERE IS CONSIDERABLE UNCERTAINTY AT THIS POINT TO
TALK ABOUT ANYTHING SPECIFIC.
AVIATION
(18Z TAFS)
ISSUED AT 943 AM PST SAT JAN 24 2026
SATELLITE IMAGERY THIS MORNING IS DRASTICALLY DIFFERENT
COMPARED TO YESTERDAY, AS MANY AREAS HAVE CLEAR SKIES. STRATUS AND
FOG LINGERS IN SOME NORTH BAY VALLEYS AND ACROSS THE INTERIOR
CENTRAL COAST, WITH THE NORTH BAY CLEARING IN A COUPLE OF HOURS.
SOUTH, THE STRATUS LOOKS BIT THICKER SO IT MAY TAKE A LITTLE WHILE
LONGER TO CLEAR, THOUGH ONCE IT DOES VFR CONDITIONS SHOULD PREVAIL
ACROSS THE REGION. OPTED TO GO A BIT MORE PESSIMISTIC FOR KSTS AND
HAVE IFR CONDITIONS RETURN. LIFR IS POSSIBLE, BUT OPTED TO NOT GO
FROM VFR TO LIFR IN THE TAF CYCLE SINCE ONLY THE MOS AND SOME HI-
RES GUIDANCE SUPPORTS THIS. THESE MODELS ALSO SHOW SOME REDUCED VIS
IN KAPC TONIGHT; HOWEVER, OFFSHORE WINDS SHOULD BE STRONGER THERE
AND KEEP FOG AT BAY.
VICINITY OF SFO...STRATUS HAS CLEARED, LEAVING SFO WITH VFR
CONDITIONS FOR THE TAF CYCLE. WINDS SHOULD SWITCH TO THE NORTH-
NORTHEAST BY LATE MORNING OR EARLY AFTERNOON, AND THEN BECOME
OFFSHORE OVERNIGHT.
SFO BRIDGE APPROACH...SIMILAR TO SFO.
MONTEREY BAY TERMINALS...CLEAR SKIES AND VFR CONDITIONS WILL
PREVAIL. WINDS OF AROUND 5-10KT WILL EVENTUALLY BECOME ONSHORE TODAY
FOR A BRIEF PERIOD, WITH OFFSHORE WINDS RETURNING TONIGHT.
MARINE
(TODAY THROUGH THURSDAY)
ISSUED AT 326 AM PST SAT JAN 24 2026
MODERATE TO FRESH NORTHERLY BREEZES TODAY AND TONIGHT. WAVE
HEIGHTS CONTINUE TO SUBSIDE TODAY. IMPROVING WIND AND SEA
CONDITIONS WILL PERSIST THROUGH THE WEEKEND TO MID NEXT WEEK.
