AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
1010 PM PST SUN JAN 17 2010

.DISCUSSION...AS OF 9:05 PM PST SUNDAY...THE WEATHER SYSTEM THAT
MOVED THROUGH THE REGION TODAY PRODUCED MODERATE AMOUNTS OF BOTH RAIN
AND WIND. STORMS THAT WILL FOLLOW THIS WEEK WILL BE SIGNIFICANTLY
STRONGER...PARTICULARLY THE STORM FORECAST TO BUFFET THE AREA
TOMORROW. STORMS WILL THEN SLAM OUR AREA ON A DAILY BASIS FOR MOST OF
THE REMAINDER OF THE WEEK. THE STORM DUE IN ON WEDNESDAY APPEARS
QUITE STRONG AS WELL.

LATEST SATELLITE IMAGERY SHOWS OUR REGION IS IN BETWEEN SYSTEMS AT
THE MOMENT. TODAY'S FRONTAL RAIN BAND HAS PUSHED WELL OFF TO OUR
EAST...AND TOMORROW'S FIERCE STORM IS GATHERING STRENGTH JUST INSIDE
OF 140W. MORE DEVELOPING WEATHER SYSTEMS CAN BE SEEN LINED UP ACROSS
THE PACIFIC ALONG 40N...BEING PUSHED RAPIDLY ALONG BY A 200 KNOT
UPPER JET. ALTHOUGH THE STORM SYSTEM DUE TO ARRIVE TOMORROW MORNING
IS STILL WELL OFFSHORE...THE STRONG UPPER JET WILL USHER IT RAPIDLY
TO THE COAST AND ALSO CONTRIBUTE TO THE STORM'S STRENGTHENING. THAT
STRENGTHENING CAN CURRENTLY BE SEEN ON IR SATELLITE IMAGERY AS CLOUD
TOPS COOL AND A CLASSIC COMA SHAPE DEVELOPS IN THE CLOUD SHIELD.
ALSO...A GOOD DEAL OF COLD AIR CAN BE SEEN DROPPING IN BEHIND THE
SYSTEM. THUS...ALL NECESSARY INGREDIENTS ARE IN PLACE TO PRODUCE A
POWERFUL STORM AND IT APPEARS HIGHLY LIKELY THAT THE MODELS ARE
CORRECT IN PRODUCING STRONG WINDS AND HEAVY RAIN OVER OUR AREA ON
MONDAY.

PRIOR TO THE ARRIVAL OF TOMORROW'S STORM...MOIST ONSHORE FLOW AND A
SLIGHTLY UNSTABLE AIRMASS WILL CONTINUE TO GENERATE PERIODS OF RAIN
OVERNIGHT. MORE WIDESPREAD RAINFALL WILL BEGIN TO OVERSPREAD THE
AREA LATE TONIGHT AS WARM ADVECTION BEGINS TO INCREASE AHEAD OF THE
RAPIDLY APPROACHING SYSTEM. RAIN RATES WILL THEN INCREASE BY MID
MORNING AND PERIODS OF HEAVY RAIN CAN BE EXPECTED FROM MID
MORNING THROUGH EARLY AFTERNOON. FRONTAL PASSAGE IS EXPECTED TO
OCCUR SOMETIME BETWEEN NOON AND MID AFTERNOON AND RAIN RATES SHOULD
DECREASE THEN. RAINFALL TOTALS WITH MONDAY'S SYSTEM ARE FORECAST TO
GENERALLY RANGE FROM ONE TO TWO INCHES...EXCEPT UP TO THREE INCHES IN
THE COASTAL MOUNTAINS. LOW LEVEL FLOW WILL BE FROM ALMOST THE DUE
SOUTH AND SO THE AREA OF BEST OROGRAPHICS...AND THUS HIGHEST PRECIP
TOTALS...WILL LIKELY BE IN THE SANTA CRUZ MOUNTAINS. LOCAL URBAN AND
SMALL STREAM FLOODING IS POSSIBLE ON MONDAY...ESPECIALLY AROUND
MIDDAY. THE AIRMASS IS FORECAST TO BECOME QUITE UNSTABLE BY MIDDAY
AND ISOLATED THUNDERSTORMS ARE POSSIBLE AS WELL.

THE BIGGEST IMPACT WITH MONDAY'S STORM WILL LIKELY BE WINDS.
PRESSURE GRADIENTS ARE FORECAST TO RAPIDLY TIGHTEN ON MONDAY MORNING
AND BY MID MORNING WIND GUSTS OF 50 MPH ARE LIKELY ALONG THE COAST...
IN THE MOUNTAINS...AND IN THE SALINAS VALLEY. WAVES DEVELOPING
ALONG THE INCOMING FRONT WILL PRODUCE EVEN STRONGER PRESSURE
GRADIENTS ON SMALLER SCALES. RECENT MODEL RUNS OF THE NAM INDICATED
THAT A WAVE ALONG THE FRONT WOULD PRODUCE A SURFACE LOW OFF THE SAN
MATEO COUNTY COAST AROUND MIDDAY ON MONDAY. THE 00Z NAM BACKED OFF ON
THIS A BIT...BUT EVIDENCE IS STILL THERE THAT LOCALLY STRONGER WINDS
WILL DEVELOP ALONG THE COAST FROM SAN MATEO COUNTY SOUTHWARD. IN
FACT...THE 00Z NAM FORECASTS 925 MB WINDS OF 70 KNOTS ALONG THE COAST
FROM ABOUT PIGEON POINT SOUTH TO ABOUT POINT SUR. ALSO...THE 12Z WRF
MODEL FORECASTS A BULLS-EYE OF 40 KNOT-PLUS SURFACE WINDS NEAR THE
NORTHERN MONTEREY COUNTY COAST AROUND MIDDAY MONDAY. BASED ON THESE
PIECES OF INFORMATION...HAVE DECIDED TO UPGRADE MONDAY'S WIND
ADVISORY TO A HIGH WIND WARNING FOR COASTAL ZONES SOUTH OF SAN
FRANCISCO. THE WIND ADVISORY REMAINS IN EFFECT FOR THE REMAINDER OF
OF THE CWA (EXCEPT INLAND NORTH AND EAST BAY VALLEYS).

WINDS SHOULD EASE OFF BY MID AFTERNOON AFTER FRONTAL PASSAGE. THUS...
THE HIGH WIND WARNING/WIND ADVISORY HAS BEEN SET TO EXPIRE A BIT
EARLIER...AT 4 PM INSTEAD OF AT 6 PM.

THE SYSTEM FORECAST TO MOVE THROUGH ON TUESDAY DOES NOT LOOK AS
POWERFUL AS MONDAY'S...AND LIKELY WILL PRODUCE LESS RAIN AND ALMOST
CERTAINLY LESS WIND. EVEN SO...A PERIOD OF HEAVY RAIN IS POSSIBLE
LATE TUESDAY MORNING AND WINDS MAY REACH ADVISORY LEVELS IN SOME OF
THE WINDIER SPOTS . MORE MINOR FLOODING MAY OCCUR.

WEDNESDAY'S STORM...WHICH HAD PREVIOUSLY LOOKED LIKE THE STRONGEST
OF THE WEEK...CONTINUES TO LOOK IMPRESSIVE AND ANOTHER ROUND OF WIND
HIGHLIGHTS WILL LIKELY BE NEEDED. IN ADDITION...BY MIDWEEK THE SOIL
WILL BE NEARING SATURATION...OR ALREADY BE THERE...AND SO ANY
ADDITIONAL HEAVY RAIN COULD LEAD TO MORE SERIOUS HYDRO ISSUES.

BY THURSDAY THE STRONG UPPER JET IS FORECAST TO DIP FARTHER SOUTH
ACROSS SOUTHERN CA AND BAJA AS THE LONGWAVE TROUGH DIGS MORE DEEPLY
OFFSHORE. THUS...THE FOCUS OF HEAVIEST RAIN AND STRONGEST WINDS
WILL SHIFT MORE INTO SOUTHERN CA ON THURSDAY. EVEN SO...OUR REGION
WILL LIKELY SEE SOME PRETTY SIGNIFICANT WINDS AND RAIN THAT DAY...
ESPECIALLY THE SOUTHERN PART OF OUR AREA.

UNSETTLED WEATHER WILL CONTINUE INTO FRIDAY. THE MEDIUM RANGE
MODELS TEND TO AGREE THAT THERE WILL FINALLY BE A BREAK FROM THE
STORMY WEATHER DURING THE UPCOMING WEEKEND AND THAT THE NEXT STORM
MAY NOT ARRIVE UNTIL LATE SUNDAY OR SUNDAY NIGHT.

&&

.AVIATION...AS OF 10:10 PM SUNDAY...THE SECOND IN THE SERIES OF
COLD FRONTS THAT ARE EXPECTED TO MOVED ACROSS THE REGION THIS COMING
WEEK IS POISED TO MOVE INTO THE REGION EARLY MONDAY MORNING. RAIN
SHOWERS AS WELL AS SOUTHERLY WINDS ARE EXPECTED TO CONTINUE TONIGHT

TO CONTINUE INCREASING OVERNIGHT WITH GALE FORCE CONDITIONS LIKELY
MONDAY. MODELS CONTINUE TO INDICATE LARGE SWELLS LATER IN THE WEEK

DANGEROUS CONDITIONS. A HIGH SURF ADVISORY HAS BEEN ISSUED FOR THE
