Area forecast discussion, Dec 25, 8:45 AM PST, 2 hours 4 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA CA
845 AM PST THU DEC 25 2008
.DISCUSSION...AS OF 8:45 AM PST THURSDAY...MAIN CONCERN TODAY IS
SHOWERS OVER THE BURN AREAS.
BEEN KEEPING A VERY CLOSE EYE ON THE RADAR SO FAR WITH BANDS OF
SHOWERS MOVING ACROSS OUR AREA THIS MORNING. MAIN CONCERN IS
OBVIOUSLY OVER THE SANTA CRUZ AND MONTEREY COUNTY BURN AREAS. OVER
THE SUMMIT PERIMETER IN SANTA CRUZ TOTALS TO THIS POINT HAVE BEEN
WELL UNDER GUIDANCE BASED OFF GROUND TRUTH PLUS FFMP. HOWEVER THERE
ARE AT LEAST TWO ADDITIONAL BANDS OF SHOWERS THAT WILL HIT THAT AREA
OVER THE NEXT COUPLE OF HOURS. PERSONS NEAR THE SUMMIT PERIMETER
SHOULD STAY ALERT ESPECIALLY THROUGH THE MORNING HOURS. OVER
MONTEREY COUNTY GOOD RAINFALL TOTALS WERE REPORTED OVER THE PAST
SIX HOURS. JUST SPOKE WITH CHP AND MONTEREY COUNTY SHERIFF AND NO
DEBRIS FLOWS WERE REPORTED TO THIS POINT. ALSO JUST GOT A SPOTTER
REPORT OF THUNDER AND SMALL HAIL IN SAN FRANCISCO WHICH IS WELL
DEPICTED BY THE VARIOUS LOCAL RADARS. IF THIS LINE HOLDS TOGETHER
TO THE BURN AREAS IT MAY CAUSE SOME PROBLEMS. LOOKS LIKE A VERY BUSY
SHIFT TODAY. WILL ISSUE ANOTHER UPDATE TO THE AFD AS TIME ALLOWS
LATER THIS MORNING.
.PREVIOUS DISCUSSION...2:54 AM PST CHRISTMAS DAY...A COLD FRONT IS
CURRENTLY MOVING ACROSS THE BAY AREA AND IT SHOWS UP NICELY ON
RADAR LOOPS. DOWNTOWN SAN FRANCISCO PICKED UP 0.17 INCH IN ONE HOUR
AS THE FRONT MOVED THROUGH. SURFACE OBS SHOW THE WIND SHIFT FROM
SOUTHEAST TO WEST AFTER THE FRONT MOVES BY...ALTHOUGH WIND SPEEDS
REMAIN MODERATE WITH 15-30 MPH WINDS COMMON. THIS FRONT WILL
CONTINUE TO PUSH SOUTHWARD THROUGH THE DISTRICT THIS MORNING
SPREADING BRIEF HEAVY RAINS IN ITS PATH. BEHIND THE FRONT CONTINUED
SHOWER CHANCES WILL LINGER ALONG WITH A SLIGHT CHANCE OF
THUNDERSTORMS AS THE COLD POOL MOVES OVER NORTHERN CALIFORNIA. BY
TONIGHT EXPECT SHOWER CHANCES TO TAPER OFF AS THE UPPER TROUGH PUSHES
EASTWARD AND DRIER AIR SPREADS ALONG THE COAST FROM THE NORTH.
ADDITIONALLY TONIGHT WITH THIS COLD AIR WILL COME LOWERING SNOW
LEVELS...TO THE 2000-3000 FOOT RANGE. HOWEVER...GIVEN THE DRIER
AIR...NOT MUCH ACCUMULATION IS EXPECTED.
FROM PREVIOUS DISCUSSION...THE MODELS HAVE CONSISTENTLY SHOWN A
PATTERN CHANGE BEGINNING ON FRIDAY AND CONTINUING WELL INTO NEXT
WEEK. A NEARLY ZONAL FLOW WILL SET UP OVER THE NORTHEAST PACIFIC...
DELIVERING PERIODS OF RAIN TO THE PAC NW AND FAR NORTHERN CA.
THE UPPER JET AND MOST OF THE RAINFALL ACTIVITY IS FORECAST TO REMAIN
WELL NORTH OF OUR AREA. HOWEVER...THE NORTH BAY WILL SEE RAIN CHANCES
DURING THE WEEKEND AND INTO EARLY NEXT WEEK AS SYSTEMS ROLLING
IN OFF THE PACIFIC DIP JUST FAR ENOUGH SOUTH TO PERHAPS BRING RAIN TO
AREAS N OF THE GOLDEN GATE. ELSEWHERE...DRY AND MILD CONDITIONS WILL
PREVAIL. TEMPERATURES WILL BE SLOW TO WARM INITIALLY DUE TO THE COLD
AIR THAT WILL ARRIVE TODAY AND TONIGHT. IN FACT...TEMPS ON FRIDAY
NIGHT WILL BE QUITE COLD AGAIN...LIKELY FALLING TO NEAR FREEZING IN
THE INLAND VALLEYS. BUT A MILDER AIRMASS WILL MAKE ITS WAY INTO OUR
AREA OVER THE WEEKEND.
&&
.AVIATION...AS OF 3:45 AM PST CHRISTMAS DAY...FRONTAL SYSTEM HAS
MOVING THROUGH THE SOUTHERN SFO BAY AREA AND WILL MOVE INTO THE
MRY BAY AREA BY MIDMORNING. NUMEROUS SHOWERS IN THE UNSTABLE
AIRMASS BEHIND THE FRONT.
SFO BAY AREA...WEST WINDS 15-20 MPH GUSTING TO 25 MPH IMMEDIATELY
BEHIND THE FRONT. WINDS WILL TEMPORARILY DECREASE LATER THIS MORNING
AS THE FRONT MOVES FURTHER AWAY BUT WILL INCREASE AGAIN IN THE
AFTERNOON AS STRONG NORTHWEST FLOW SETS UP. CEILINGS CURRENTLY AROUND
2500 FEET BUT SHOULD RISE TO 3000-4000 FEET LATER THIS MORNING AND
THIS AFTERNOON. THERE IS A POSSIBILITY OF AN ISOLATED AFTERNOON
THUNDERSTORM WITH TEMPORARY LOWER CEILINGS.
MRY BAY AREA...RAIN WITH SOUTHEAST WINDS 15-20 MPH GUSTING TO 30 MPH
IMMEDIATELY AHEAD OF FRONT WILL BECOME SHOWERY WITH WINDS
SWITCHING TO NORTHWEST AFTER AROUND 6 AM. AS IN THE SFO BAY
AREA...WINDS WILL DECREASE LATER THIS MORNING BUT WILL INCREASE AGAIN
IN THE AFTERNOON. CEILINGS WILL LOWER TO AROUND 3000 FEET. THERE IS
A POSSIBILITY OF AN ISOLATED AFTERNOON THUNDERSTORM ESPECIALLY IN
THE SNS VLY.
&&
.MARINE...AS OF 10 PM PST WEDNESDAY...A HIGH SURF ADVISORY WAS ISSUED
FOR THE COAST FROM 12 NOON THURSDAY TO 9 PM FRIDAY. ENP WAVE MODEL
FORECASTS HAVE BEEN CONSISTENT WITH THIS FORECAST. BUOY 59 REPORTED
SEAS UP NEAR 25 FEET EARLIER TODAY WITH THE SHORTWAVE OFF THE
COAST. IF SUBSEQUENT ENP MODEL RUNS SHOW SWELL REACHING OVER 20 FEET
THE ADVISORY MAY THEN NEED TO BE UPGRADED TO A WARNING SOMETIME ON
THURSDAY. REGARDING COASTAL FLOODING POTENTIAL WHAT MAY HELP LIMIT
COASTAL FLOODING IS THE STRONG NORTHERLY COMPONENT TO THE SWELL
DIRECTION. LARGE BREAKING SWELL WILL PROBABLY LEAD TO LOCALIZED MINOR
BEACH EROSION. A HIGH TIDE AT 6.1 FEET OCCURS AT 10 AM FRIDAY MORNING
WHICH COINCIDES WITH PEAK SWELL.
