AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
1015 PM PST THU FEB 25 2010

.DISCUSSION...AS OF 8:55 PM THURSDAY...CLOUDS HAVE OVERSPREAD OUR
AREA THIS EVENING IN ADVANCE OF AN INCOMING PACIFIC WEATHER SYSTEM.
PRECIPITATION...HOWEVER...REMAINS WELL OFFSHORE AT THIS TIME. 00Z
MODEL OUTPUT INDICATE THAT WARM ADVECTION RAIN WON'T GET STARTED IN
THE NORTH BAY UNTIL AFTER MIDNIGHT...AND THAT RAIN WILL REMAIN
CONFINED TO THE NORTH BAY COUNTIES UNTIL ABOUT SUNRISE. THE MORNING
COMMUTE FOR AREAS SOUTH OF SAN FRANCISCO COULD VERY WELL BY DRY.
THE MAIN BAND OF PRECIPITATION AHEAD OF THE ADVANCING COLD FRONT WILL
SWING THROUGH THE SF BAY AREA DURING THE AFTERNOON HOURS...AND
THROUGH THE MONTEREY BAY AREA DURING THE EARLY EVENING. RAIN COULD
VERY WELL BE HEAVY FOR A TIME JUST AHEAD OF THE COLD FRONT. MINOR
URBAN NUISANCE FLOODING COULD OCCUR IN THE AFTERNOON AND EARLY
EVENING AND SOME OF THE SMALL CREEKS AND STREAMS COULD REACH
BANKFULL. BUT BECAUSE THE FRONT IS FORECAST TO MOVE THROUGH RATHER
QUICKLY...NO MAJOR HYDRO ISSUES ARE ANTICIPATED. RAINFALL TOTALS
THROUGH FRIDAY EVENING ARE FORECAST TO RANGE FROM 0.5 TO 1.5 INCHES
AT LOWER ELEVATIONS AND FROM 1.5 TO 3 INCHES IN THE MOUNTAINS.

SOUTHERLY WINDS WILL INCREASE LATE TONIGHT AND FRIDAY MORNING AHEAD
OF THE FRONT. FROM LATE FRIDAY MORNING THROUGH EARLY FRIDAY EVENING
WIND GUSTS AS HIGH AS 40 MPH ARE LIKELY NEAR THE COAST AND IN THE
HILLS. THIS COULD BE A MARGINAL WIND ADVISORY EVENT WITH SOME
ISOLATED GUSTS TO 50 MPH IN THE WINDIEST SPOTS. HOWEVER...THE 00Z
WRF BACKED OFF SLIGHTLY ON ITS SURFACE WIND SPEED FORECAST AND SO
WILL HOLD OFF ON ANY WIND ADVISORIES FOR THE TIME BEING.  IN ANY
CASE...SATURATED SOILS COMBINED WITH GUSTY WINDS COULD RESULT
IN SOME DOWNED TREES AND POSSIBLE POWER OUTAGES.

IR SATELLITE CURRENTLY SHOWS A LARGE AREA OF COLD AND UNSTABLE AIR
CENTERED NEAR 40N/140W. THIS UNSTABLE AIRMASS IS FORECAST TO REACH
OUR COASTAL WATERS FRIDAY AFTERNOON AFTER FRONTAL PASSAGE...AND
THEN BEGIN TO MOVE INLAND BY EARLY EVENING. THE LONG-RANGE LIGHTNING
DETECTION NETWORK DOES NOT CURRENTLY SHOW ANY STRIKES IN THE
UNSTABLE AIRMASS. HOWEVER...THE 00Z NAM INDICATES THAT THERE WILL BE
SUFFICIENT INSTABILITY ARRIVING ALONG OUR COAST LATE TOMORROW TO
WARRANT INCLUSION OF AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS IN THE
FORECAST...BEGINNING OVER THE COASTAL WATERS TOMORROW AFTERNOON AND
THEN INLAND TOMORROW NIGHT. SMALL HAIL AND BRIEF HEAVY DOWNPOURS WILL
LIKELY ACCOMPANY SHOWERS AND ISOLATED THUNDERSTORMS ON FRIDAY NIGHT.

A CLOSED UPPER LOW IS FORECAST TO DEVELOP OFFSHORE ON FRIDAY NIGHT
AND THEN SLIDE INLAND ALONG THE SOUTH-CENTRAL CA COAST ON SATURDAY.
BEST CHANCES OF SHOWERS ON SATURDAY WILL BE IN AREAS CLOSER TO THE
LOW CENTER (I.E., THE SOUTHERN PART OF OUR FORECAST AREA). IN FACT...
THE 00Z MODELS INDICATE THE NORTH BAY WILL BE MOSTLY DRY ON
SATURDAY. CLEARING WILL THEN OCCUR ON SATURDAY NIGHT AS THE UPPER LOW
MOVES INTO SOUTHERN ARIZONA. VALLEY FOG IS LIKELY TO FORM LATE
SATURDAY NIGHT. AFTER THE MORNING FOG CLEARS...SUNDAY WILL BE A
MOSTLY SUNNY AND MILD DAY WITH HIGHS MOSTLY IN THE LOWER TO MID
60S. DRY WEATHER WILL CONTINUE INTO MONDAY AS WELL AS A SHORTWAVE
RIDGE REMAINS OVER CA. THE MEDIUM RANGE MODELS AGREE THAT LIGHT TO
MODERATE AMOUNTS OF RAINFALL WILL OCCUR FROM MONDAY NIGHT THROUGH
TUESDAY NIGHT AS THE NEXT SYSTEM MOVES INTO CA. ALTHOUGH THAT SYSTEM
WILL ALMOST CERTAINLY NOT PRODUCE AS MUCH RAIN AS FRIDAY'S...IT WILL
BE COLDER AND COULD VERY WILL DROP A LITTLE SNOW ON BAY AREA PEAKS.
ANOTHER COOL WEATHER SYSTEM IS FORECAST TO FOLLOW LATE IN THE
WEEK.

&&

.AVIATION...AS OF 10:15 PM PST THURSDAY...HIGH CLOUDS ARE GRADUALLY
LOWERING AHEAD OF THE APPROACHING COLD FRONT. RAIN IS EXPECTED TO
SPREAD FROM NORTH TO SOUTH ACROSS THE REGION AFTER MIDNIGHT TONIGHT.
RAIN WILL BEGIN IN THE NORTH BAY REACHING THE BAY AREA AROUND 15-17Z
FRIDAY MORNING THEN CONTINUING THROUGH THE DAY.

VICINITY OF KSFO...VFR CONDITIONS EXPECTED THROUGH TONIGHT WITH
ONLY A SCT-090 AND BKN-OVC 180200. CIGS WILL GRADUALLY LOWER TO
AROUND 035-045 AFTER MIDNIGHT WITH -RA BEGINNING AROUND 15-17Z FRIDAY
MORNING. SOUTH TO SOUTHEASTERLY WINDS ARE EXPECTED LATER TONIGHT
WITH SUSTAINED SOUTHEASTERLY WIND OF 15-20 KT WITH GUST TO 25 KT
EXPECTED AFTER 16Z.

KSFO BRIDGE APPROACH...SAME AS KSFO.

MRY BAY AREA TERMINALS...VFR CONDITIONS EXPECTED THROUGH TONIGHT WITH
MAINLY HIGH CLOUDS OVER THE TERMINALS. WINDS WILL VEER TO THE
SOUTHEAST LATER TONIGHT AHEAD OF THE APPROACHING FRONT. RAIN
CHANCES WILL BEGIN AFTER 19Z FRIDAY MORNING WITH -RA EXPECTED
AROUND 21Z. CIGS WILL LOWER TO 020-030 AFTER 21Z WITH THE ARRIVAL OF
THE RAIN.

STORM SYSTEM. LIGHT RAIN MAY FORM NORTH OF THE GOLDEN GATE LATER
THIS EVENING OR AFTER MIDNIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

A STRONG WEATHER SYSTEM WILL MOVE INTO THE FORECAST AREA FRIDAY.

ISOLATED THUNDERSTORMS CAPABLE OF PRODUCING LIGHTNING AND SMALL HAIL.
STRONG AND GUSTY SOUTHERLY WINDS WILL DEVELOP IN THE HILLS AND NORTH
