SYNOPSIS
ISSUED AT 332 AM PDT MON JUN 2 2025
NEAR OR SLIGHTLY BELOW NORMAL TEMPERATURES WILL CONTINUE THIS WEEK
ALONG WITH CONTINUED DRY WEATHER. HIGHS MAINLY 60S ALONG THE COAST,
70S BAYSIDE AND 80S WELL INLAND. NIGHT AND MORNING LOW CLOUDS
FOLLOWED BY AFTERNOON AND EVENING CLEARING NEAR THE COAST.
NEXT INLAND WARMING TREND MAY OCCUR BY NEXT WEEKEND.
SHORT TERM
(TODAY AND TONIGHT)
ISSUED AT 332 AM PDT MON JUN 2 2025
KEY MESSAGES:
-NIGHTTIME AND MORNING STRATUS AND FOG.
-NEAR OR SLIGHTLY BELOW NORMAL TEMPERATURES.
WATER VAPOR IMAGERY THIS MORNING SHOWS THE UPPER LOW TRAVERSING DOWN
THE COAST OF CA. MINIMAL HIGH CLOUD IS BEING OBSERVED; HOWEVER, IF
YOU LOOK AT THE NIGHTTIME MICROPHYSICS AND FOG DIFFERENCE YOU CAN
SEE THE MARINE LAYER HAS MADE A TRIUMPHANT RETURN INTO THE CENTRAL
COAST AND BAY AREA. THIS REDUCED THE CHANCE OR EVEN OBLITERATED,
ESPECIALLY HERE IN MONTEREY, THE CHANCE TO SEE THE AURORA LAST
NIGHT OR THIS MORNING. FOR AREAS WHERE THE STRATUS HASN'T
INFILTRATED, HOPEFULLY YOU GOT A CHANCE TO TRY AND SEE THE BEAUTY
OF THE NORTHERN LIGHTS OVER THE LAST TWO DAYS.
IN TERMS OF TODAY'S FORECAST, THE LOW IS EXPECTED TO SLIDE DOWN
THE COAST WHILE A CLOSED LOW MOVES INTO THE DESERT SOUTHWEST.
WINDS WILL SHIFT TO THE SOUTH OR SOUTHEAST THIS MORNING AND HELP
ERADICATE THE STRATUS. TEMPERATURES SHOULD REMAIN SEASONABLY COOL
TODAY, WITH STRATUS RETURNING LATE TONIGHT.
LONG TERM
(TUESDAY THROUGH SUNDAY)
ISSUED AT 332 AM PDT MON JUN 2 2025
KEY MESSAGES:
-MARINE LAYER RETURNS, WITH NIGHT AND MORNING CLOUDS EACH DAY.
-NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES THROUGH MUCH OF THE
WEEK.
-TEMPERATURES INCREASE NEXT WEEKEND.
THE CLOSED UPPER LEVEL LOW FROM MONDAY SHOULD BE WEST OF SOUTHERN CA
BY TUESDAY MORNING AND BEGIN PUSHING INLAND THROUGHOUT THE DAY. SOME
GUIDANCE SHOWS A RIBBON OF MOISTURE TRYING TO ADVECT INTO CENTRAL
AND NORTHERN CA, ALONG WITH SOME INSTABILITY. THE BEST CHANCE TO
SEE BOTH OF THESE INGREDIENTS IS OVER SOUTHERN MONTEREY AND SAN
BENITO COUNTIES; HOWEVER, NOT MANY MODELS ARE BITING ON TO THIS.
WE'LL LIKELY BE UNDER EITHER WEAK TROUGHING TO ZONAL FLOW AT THIS
TIME, WHICH SHOULD INHIBIT ANY THUNDERSTORM DEVELOPMENT. WE MIGHT
SEE SOME CUMULUS POP UP OVER THE RIDGES TUESDAY AFTERNOON WHILE
THE BEST CHANCES FOR THUNDERSTORMS REMAIN OVER THE SOUTHERN SIERRA
OR PERHAPS SOUTHERN CA.
BEYOND THAT, LOOK FOR THE JUNE GLOOM OF NIGHTTIME AND MORNING
STRATUS THROUGH THE WEEK AND NEAR NORMAL TO SLIGHTLY BELOW NORMAL
TEMPERATURES. A WARMING TREND, ESPECIALLY FOR INTERIOR LOCATIONS,
LOOKS LIKELY FOR THE WEEKEND.
AVIATION
(06Z TAFS)
ISSUED AT 919 PM PDT SUN JUN 1 2025
CURRENT SATELLITE TRENDS INDICATE THAT LOW STRATUS IS FILTERING
INTO THE NORTH BAY TERMINALS RESULTING IN MVFR CIGS WITH A MORE
ROBUST MARINE LAYER THAT IS NO LONGER BEING COMPRESSED. VFR IS
EXPECTED TO PREVAIL THROUGH THE FORECAST PERIOD FOR THE BAY AREA
TERMINALS. HOWEVER, LOW MARINE STRATUS MAY DROP CIGS INTO
MVFR/IFR AT TIMES OVERNIGHT. MONTEREY BAY TERMINALS ARE EXPECTED
TO REMAIN VFR OVERNIGHT THROUGH MID MONDAY MORNING.
VICINITY OF SFO...MARINE LAYER STRATUS IS DEVELOPING LATE THIS
EVENING IN THE VICINITY OF KSFO AND KOAK, AND MAY INTERMITTENTLY
IMPACT THE TERMINALS WITH MVFR/IFR CIGS AT TIMES DURING THE
OVERNIGHT PERIOD. GUSTY WINDS HAVE EASED AND ARE NOT EXPECTED TO
BE AS BREEZY MONDAY AS WE'VE SEEN THE PAST COUPLE OF DAYS.
SFO BRIDGE APPROACH...SIMILAR TO SFO.
MONTEREY BAY TERMINALS...STEADY ONSHORE FLOW, BREEZY AT TIMES,
WILL HELP KEEP MVFR CIGS THROUGH THE OVERNIGHT HOURS INTO THE
MIDDLE OF MONDAY MORNING, WITH VFR EXPECTED FOR THE REMAINDER OF
THE FORECAST PERIOD ON MONDAY.
MARINE
(TODAY THROUGH SATURDAY)
ISSUED AT 332 AM PDT MON JUN 2 2025

GALE FORCE GUSTS LINGERING OVER THE FAR NORTHERNMOST OUTER COASTAL
WATERS. ROUGH SEAS AND SIGNIFICANT WAVE HEIGHTS OF UP TO 20 FT
CONTINUE ACROSS THE NORTHERN OUTER WATERS AND UP TO 15 FT ACROSS
THE SOUTHERN OUTER WATERS THROUGH EARLY MONDAY AFTERNOON. WINDS
GRADUALLY EASE BY TUESDAY BUT SEAS WILL REMAIN ROUGH WITH ELEVATED
