AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
859 PM PDT SAT JUN 2 2012

.DISCUSSION...AS OF 8:55 PM PDT SATURDAY...SINCE YESTERDAY THE
UPPER LEVEL RIDGE OVER THE WEST HAS WEAKENED AND MOVED TO THE
EAST...SOMETHING THAT RESULTED IN ABOUT 5 DEGREES C OF COOLING ALOFT
OVER THE PAST 24 HOURS. IN ADDITION...THERE HAS BEEN A STRONG
INLAND INFLUX OF MARINE AIR AS ONSHORE FLOW INCREASED. THESE
DEVELOPMENTS LED TO A DECREASE IN INLAND HIGH TEMPERATURES OF 5 TO
15 DEGREES FROM YESTERDAY. COASTAL AREAS SAW ONLY SLIGHT COOLING.
AND NEAR MONTEREY BAY...AN AREA WHICH RECEIVED MORE AFTERNOON SUN
COMPARED TO FRIDAY...AFTERNOON HIGHS WERE SLIGHTLY WARMER.

SUNDAY WILL PROBABLY START OFF MUCH LIKE TODAY WITH WIDESPREAD LOW
CLOUDS NEAR THE COAST AND AREAS OF LOW CLOUDS INLAND. INLAND
VALLEY TEMPERATURES WILL PROBABLY COOL A FEW MORE DEGREES AS
STRONG ONSHORE FLOW CONTINUES. COASTAL AREAS MAY SEE EVEN MORE
AFTERNOON SUN TOMORROW IF SUBSIDENCE IN ADVANCE OF THE INCOMING
WEATHER SYSTEM CLEARS LOW CLOUDS EARLIER AS EXPECTED. BUT MOST OF
THE AREA PROBABLY WON'T SEE MUCH CHANGE IN TEMPS.

SIGNIFICANT CHANGE IS IN STORE FOR OUR AREA LATE SUNDAY NIGHT INTO
MONDAY WHEN A LATE SEASON PACIFIC WEATHER SYSTEM MOVES INTO
NORTHERN CALIFORNIA. THE NAM HAS BEEN TRENDING A BIT FARTHER TO
THE NORTH WITH THE MONDAY SYSTEM. ALSO...THE GFS HAS TRENDED DRIER
FROM ITS 12Z RUN TO ITS 18Z RUN. EVEN SO...THE 00Z NAM STILL
SPREADS LIGHT RAIN OVER MUCH OF OUR FORECAST AREA LATE SUNDAY
NIGHT INTO MONDAY AS THE COLD FRONT SWEEPS THROUGH. THE COLDEST
AND MOST UNSTABLE AIRMASS IS PROJECTED TO MOVE INLAND WELL TO OUR
NORTH AND SO THUNDERSTORMS ARE NOT CURRENTLY ANTICIPATED IN OUR
FORECAST AREA. QPF FROM THE MOST RECENT MODEL OUTPUT IS MOSTLY UNDER
A TENTH OF AN INCH IN OUR AREA...WITH SLIGHTLY MORE OVER THE NORTH
BAY MOUNTAINS. THE UPPER TROUGH AXIS IS NOT FORECAST TO MOVE
THROUGH UNTIL LATE MONDAY EVENING...BUT BY THEN MOISTURE WILL BE
LACKING AS PRECIPITABLE WATER DECREASES FROM NEARLY 1.25 INCHES
PRIOR TO COLD FRONTAL PASSAGE TO LESS THAN A HALF INCH AFTER.
THUS...POST FRONTAL SHOWER ACTIVITY WILL PROBABLY BE ISOLATED AT
BEST AND CONFINED MAINLY TO THE NORTH BAY LATE MONDAY AFTERNOON
AND EARLY MONDAY EVENING.

THIS SYSTEM WILL BRING WITH IT AN UNSEASONABLY COOL AIRMASS.
850 MB TEMPERATURES ARE FORECAST TO DROP AS LOW AS 2 DEG C BY
LATE MONDAY NIGHT. THIS WILL MEAN MUCH BELOW NORMAL TEMPERATURES
ACROSS OUR AREA FOR MONDAY AND TUESDAY...ESPECIALLY FOR INLAND
AREAS WHERE HIGHS BOTH DAYS WILL BE AS MUCH AS 15 DEGREES BELOW
THE EARLY JUNE NORMAL.

A WARMING TREND IS FORECAST FOR THE SECOND HALF OF THE WEEK AS H5
HEIGHTS CLIMB BACK UP NEAR 580 DM. BOTH THE GFS AND ECMWF MOS
GUIDANCE FORECAST TEMPERATURES TO RETURN TO NEAR NORMAL BY
THURSDAY AND A BIT ABOVE NORMAL BY FRIDAY.

&&

.AVIATION...AS OF 4:30 PM PDT SATURDAY...STRATUS BANKED UP ALONG
THE COASTAL HILLS WILL SPREAD ONSHORE EARLY TONIGHT UNDER STRONG
ONSHORE FLOW. GUSTY WEST WINDS TO 35 KT BLOWING THROUGH THE GAP
INTO SFO. THIS SHOULD DECREASE AFTER 03Z.

VICINITY OF KSFO...VFR THROUGH AT LEAST 02Z. CIGS FORECAST TO
RETURN EARLY THIS EVENING WITH IFR LIKELY AFTER 03-04Z. WEST WINDS
25-30 KT GUSTS TO 35 KT DECREASING BELOW 25 KT BY 03Z.

KSFO BRIDGE APPROACH...CIGS FORECAST TO RETURN EARLY THIS EVENING
WITH IFR LIKELY BY 04Z. WEST WINDS 15-20 KT DECREASING AFTER 03Z.

MONTEREY BAY AREA TERMINALS...LATEST SATELLITE IMAGE SHOWS STRATUS
HAS JUST ABOUT CLEARED THE SRN MRY BAY AREA. THIS SHOULD ALLOW FOR
AT LEAST A COUPLE HOURS OF VFR. ONSHORE FLOW WILL ALLOW STRATUS
TO RETURN QUICKLY SO IFR CIGS EXPECTED BY 03-04Z.
