UPDATE
ISSUED AT 640 AM PDT TUE JUN 2 2026
FIRST AND FOREMOST, THE DENSE FOG ADVISORY HAS BEEN CANCELLED.
WHILE THERE IS PATCHY FOG STILL BEING REPORTED AROUND THE REGION
DENSE FOG IS NOT. LOWER END VSBY THIS MORNING WILL RANGE FROM 2
TO 4 MILES. WHY NOT DENSE FOG? LIKELY TIED TO FULL JUNE GLOOM
MODE. EARLY FRAMES FROM THE VIS SATELLITE IMAGERY SHOWS A CLASSIC
MARINE LAYER/STRATUS PUSH ACROSS THE REGION AND INLAND VALLEYS.
PROFILES NEAR BODEGA BAY AND ACARS SOUNDINGS WITH VAPOR TRACES
SHOWS THE DEPTH AROUND THE 1300-1600 FT RANGE. THE DEEPENING
MARINE LAYER HAS A HARDER TIME SUPPORTING DENSE FOG. DRIZZLE
AND/OR MIST ON THE OTHER HAND WILL STILL BE POSSIBLE THIS MORNING.
WHAT ABOUT SEEING THE SUN TODAY? MARINE LAYER STRATUS WILL PERSIST
THROUGH MID TO LATE MORNING BEFORE ROLLING BACK TO THE COAST.
EXPECT INLAND SUNSHINE, BUT COASTAL AREAS WILL STRUGGLE TO SEE THE
SUN. IT GOES WITHOUT SAYING, BUT TEMPERATURES WILL BE ON THE
COOLER SIDE TODAY GIVEN THE CLOUDS AND PERSISTENT ONSHORE FLOW.
NO OTHER UPDATES NEEDED AT THIS TIME.

SHORT TERM
ISSUED AT 1204 AM PDT TUE JUN 2 2026
(TODAY AND TONIGHT)
EXPECTING AREAS OF DENSE FOG OVERNIGHT ALONG THE MONTEREY BAY AND
BIG SUR COASTLINE, SIMILAR TO EARLY MONDAY MORNING IN THE PRE-DAWN
HOURS WITH A MORE ROBUST MARINE LAYER GETTING SOME ASSISTANCE
PUSHING INLAND FROM A WEAK UPPER TROUGH THAT WILL CONTINUE TO SHIFT
SOUTH TOWARD SOCAL FOR THE REMAINDER OF THE OVERNIGHT AND TODAY.
MEANWHILE, WITH WEAK UPPER LEVEL RIDGING JUST TO OUR NORTH, LEAVES
THE BAY AREA AND CENTRAL COAST UNDER UNORGANIZED H30 JET FLOW EARLY
THIS MORNING THAT BEGINS TO INCREASE AND BECOME MORE ORGANIZED
THROUGHOUT THE DAY. TEMPERATURES TODAY WILL BE NEAR OR SLIGHTLY
COOLER THAN MONDAYS HIGHS. HIGHER ELEVATIONS IN THE FAR NORTH BAY
TONIGHT UNDER THE INFLUENCE OF THE EAST SHIFTING UPPER RIDGE WILL
ONCE AGAIN SEE WARMER THAN NORMAL TEMPERATURES FROM THERMAL BELTING,
WHILE SIMILARLY TO THE FAR SOUTH IN HIGHER ELEVATIONS OF THE SANTA
LUCIAS IN SOUTHERN MONTEREY COUNTY THE UPPER LOW HELPS PROMOTE A
WEAK FETCH OF OFFSHORE FLOW AND THERMAL BELTING, AN INTERESTING
PATTERN WITH H85 TEMPERATURES ROUGHLY IN THE 75TH PERCENTILE FOR
THIS TIME OF YEAR. OTHERWISE OVERNIGHT LOWS INTO WEDNESDAY WILL BE
IN THE LOW TO MID-50S FOR LOWER LYING AREAS BOTH NEAR THE COAST
AND INLAND.
LONG TERM
ISSUED AT 1204 AM PDT TUE JUN 2 2026
(WEDNESDAY THROUGH MONDAY)
THE REMAINDER OF THE WORK WEEK WILL ONLY HAVE SLIGHT FLUCTUATIONS IN
DAILY TEMPERATURES AS THE UPPER LEVEL LOW ORGANIZES IN THE GULF OF
ALASKA WITH ITS ASSOCIATED TROUGH DEEPENING SOUTHWARD TOWARD OUT
LATITUDE, ARRIVING IN EARNEST LATER FRIDAY, AND LOWERING OUR
TEMPERATURES 5-10 DEGREES BELOW NORMAL FOR THE WEEKEND INTO THE
BEGINNING OF NEXT WEEK. THE TROUGHING PATTERN APPEARS TO PERSIST
PAST THE CURRENT EXTENDED FORECAST, HOWEVER THE FORECAST CONTINUES
TO REMAIN DRY, BUT POCKETS OF COASTAL DRIZZLE AND FOG MAY BE A
NUISANCE UP AND DOWN OUR PACIFIC COASTLINE EACH NIGHT AND EARLY
MORNING.

(18Z TAFS)
ISSUED AT 131 PM PDT TUE JUN 2 2026
MOST SITES ARE SEEING VFR WITH THE EXCEPTION OF HAF WHICH LOOKS TO
HAVE SOME MOMENTARY BREAKS IN MVFR CIGS, BUT LOOKS TO KEEP CIGS
THROUGH THE DAY. MODERATE TO BREEZY WINDS ARE BUILDING ACROSS MUCH
OF THE REGION WITH WEST TO NORTHWEST WINDS FOR MOST AREAS, BUT SOUTH
TO SOUTHWEST WINDS IN THE NORTH BAY SITES. WINDS WILL BEGIN TO
REDUCE INTO THE EVENING AND WILL BE LIGHTER OVERNIGHT. CIGS REBUILD
THIS EVENING AROUND THE MONTEREY BAY AND ALONG THE COAST, FOLLOWED
BY OAK INTO THE NIGHT. MOMENTS OF IFR CIGS LOOK TO AFFECT APC IN THE
LATE NIGHT WHILE THE MONTEREY BAY TERMINALS GO LIFR. POCKETS OF FOG
AND MIST WILL BE POSSIBLE ALONG THE COAST AND POTIONS OF THE NORTH
BAY INTO WEDNESDAY MORNING.
VICINITY OF SFO...MODERATE WEST WINDS WITH GUSTS UP TO 25 KTS LAST
INTO THE NIGHT BEFORE REDUCING.CLOUD COVER LOOKS TO MOSTLY STAY TO
THE NORTH AND WEST OF THE TERMINAL OVERNIGHT, BUT WILL LEAD TO
SCATTERED CLOUDS AROUND 1000 FT AGL. THESE CLOUDS WILL THIN INTO THE
MID TO LATE MORNING AS MODERATE WEST WINDS ARRIVING
SFO BRIDGE APPROACH...SIMILAR TO SFO.
MONTEREY BAY TERMINALS...VFR LASTS AND MODERATE WINDS LAST INTO THE
EVENING BEFORE WINDS WEAKEN AND IFR CIGS MOVE OVER THE TERMINALS.
WINDS BECOME LIGHTER INTO THE LATE NIGHT AND CIGS FALL TO LIFR
LEVELS WITH FOG AND MIST AFFECTING VISIBILITIES. AN OTTER EDDY LOOKS
TO FORM OVER THE MONTEREY BAY IN THE LATE NIGHT, CAUSING SOME
MOVEMENT IN CIGS FROM THE OSCILLATION, WHICH COULD LEAD TO SOME
SHORT-LIVED IMPROVEMENTS TO CIGS AND VISIBILITIES, BUT CLEARING IS
EXPECTED BEYOND THE TAF PERIOD.
