AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
945 PM PST FRI DEC 12 2008

.SYNOPSIS...A LARGE...COLD LOW PRESSURE SYSTEM OVER THE PACIFIC
NORTHWEST WILL MOVE SOUTH ACROSS CALIFORNIA THIS WEEKEND. THE
WEATHER WILL TURN COOLER...AND THERE WILL BE A CHANCE OF MOSTLY
LIGHT RAIN. STRONG WINDS ARE LIKELY IN THE MOUNTAINS AND DESERTS
SATURDAY. A WAVE ASSOCIATED WITH THE LOW PRESSURE SYSTEM WILL MOVE
THROUGH THE AREA MONDAY AND BRING MORE WIDESPREAD RAIN...WITH SNOW
IN THE MOUNTAINS. UNSETTLED WEATHER WILL CONTINUE MOST OF NEXT WEEK
WITH BELOW NORMAL DAYTIME TEMPERATURES.

&&

.DISCUSSION...FOR SOUTHWEST CALIFORNIA INCLUDING SAN DIEGO...
ORANGE...SOUTHWEST SAN BERNARDINO AND WEST RIVERSIDE COUNTIES.

MARINE LAYER CONTINUED ITS RAPID ASCENT...WITH THE INVERSION NOW
AT/ABOVE 3000 FEET MSL. THIS IS ENOUGH THAT SOME LIGHT RAIN COULD
OCCUR BY MORNING...THOUGH AMOUNTS WILL BE VERY LIGHT. THE FIRST WAVE
THAT MOVED THROUGH TODAY AND BROUGHT A FEW LIGHT SHOWERS IS NOW OVER
ARIZONA...BUT THE NEXT WAVE IS ALREADY MOVING INTO FAR N CA. THE
COLD AIR ADVECTION AND STRENGTHENING HEIGHT GRADIENTS/WINDS ALOFT
WILL RESULT IN SOME GUSTY WINDS OVER THE MTN CRESTS/EAST SLOPES/
DESERTS...LOCALLY OVER 50 MPH...WITH THE BEST SUPPORT OVER SAN
BERNARDINO COUNTY. I WILL LET THE HIGH WIND WATCH CONTINUE FOR THE
UPPER DESERTS FOR SAT...IT LOOKS LIKE A BORDERLINE CASE BETWEEN A
HIGH WIND WARNING AND WIND ADVISORY. A WIND ADVISORY WILL LIKELY BE
NEEDED OVER THE REST OF THE MTNS/DESERTS SATURDAY. THERE IS NOT MUCH
OF A VORT-MAX MOVING THROUGH SO-CAL...BUT THE VORT AXIS WILL PASS BY
TO THE NORTH/NORTHEAST SAT EVENING...THAT WILL BE THE BEST CHANCE OF
RAIN THIS WEEKEND. MOISTURE WILL MOSTLY REMAIN BELOW 800 MB...WHICH
IS AROUND THE SNOW LEVEL...SO IF ANY SNOW FALLS IN THE
MTNS...ACCUMULATIONS WILL PROBABLY STAY ONE INCH OR LESS.

RAIN CHANCES WILL INCREASE MONDAY AS A SWATH OF FAIRLY DEEP PACIFIC
MOISTURE AND STRONG ONSHORE/W-SW FLOW IN THE FAVORED 850-700 MB
LAYER OCCUR. THIS COULD BRING SOME SUBSTANTIAL OROGRAPHIC PRECIP DUE
TO THE 850 MB WINDS OF AROUND 35 KNOTS...A SATURATED AIRMASS AND
EVEN A LITTLE BIT OF WARM AIR ADVECTION TO AID WITH THE LIFTING.
THIS WILL LIKELY BE A STEADY RAIN EVENT LASTING QUITE A FEW
HOURS...SO WHILE HOURLY RAINFALL RATES DO NOT APPEAR TO BE
HEAVY...THE LONGEVITY COULD RESULT IN LOCALLY HIGH AMOUNTS...2-3
INCHES ON THE COASTAL MTN SLOPES DURING A 12-HOUR PERIOD. SNOW
LEVELS WILL BE BETWEEN 4000 AND 5000 FEET...AND GIVEN THE DEEP MOIST
LAYER...HEAVY SNOW OF MORE THAN A FOOT COULD FALL ABOVE 6000 FEET.

THE CENTER OF THE UPPER LOW SHOULD BE NEARBY AROUND TUE NIGHT/WED.
THERE WILL LIKELY BE A LOT OF CONVECTION AS THE 500 MB TEMPS SHOULD
FALL BELOW -25 DEG C...SO HEAVIEST HOURLY-RATE OF PRECIP WILL BE
POSSIBLE DURING THIS TIME-FRAME...THOUGH 12-24 HOUR TOTALS WILL BE A
LITTLE LESS THAN AROUND MONDAY. STRONG CYCLONIC FLOW AND SHEAR WILL
BRING A THREAT OF WATERSPOUTS TUE NIGHT/WED...AND AN ISOLATED
TORNADO OVER LAND IS POSSIBLE. THERE WILL BE A THREAT OF HAIL AS
WELL.

UPPER TROUGHING WILL CONTINUE THE REST OF THE WEST OVER THE WESTERN
US LATE IN THE WEEK...AND MORE WAVES COULD MOVE THROUGH THE AREA AND
BRING MORE SHOWERS. THE WEATHER NEXT WEEK IS ASSOCIATED WITH A
LARGE-SCALE PATTERN SHIFT WHICH WILL MAKE STORM SYSTEMS MORE LIKELY
THAN NORMAL IN THE NEXT FEW WEEKS AND THE FAIR AND OFTEN
UNSEASONABLY WARM WEATHER OF RECENT WEEKS MUCH LESS LIKELY.

.AVIATION...
130400Z...LATEST MDCRS SOUNDINGS SHOW MARINE LAYER DEPTH HAS
INCREASED TO 3000 FT. STRATUS WILL CONTINUE TO FILL IN ALONG THE
COAST AND PUSH INLAND. MARINE LAYER WILL GRADUALLY DEEPEN THROUGH
SATURDAY. DRIZZLE AND LIGHT RAIN ARE POSSIBLE BEGINNING EARLY
SATURDAY MORNING. BASES WILL RANGE FROM 2000 TO 3000 FT
MSL...LOCALLY DOWN TO 1000 FT MSL IN DRIZZLE. VISIBILITIES SHOULD
REMAIN AT OR ABOVE 5 SM.

ABOVE THE MARINE LAYER...VARIABLE MID AND HIGH CLOUDS AND
UNRESTRICTED VISIBILITIES.

&&

.MARINE...VERY HIGH TIDES OF 7 FEET OR GREATER ARE EXPECTED EACH
MORNING THROUGH SUNDAY MORNING. AT THE SAN DIEGO BROADWAY PIER THE
HIGHEST TIDE OF 7.7 FEET OCCURS SATURDAY MORNING. SWELL AND SURF
WILL INCREASE SATURDAY AFTERNOON AS A STORM APPROACHES FROM THE
NORTH. WINDS WILL INCREASE OVER THE COASTAL WATERS SATURDAY
AFTERNOON THROUGH SUNDAY.

...COLD AND RAINY WEATHER PATTERN FOR SOUTHWEST CALIFORNIA...

A DEEP LOW PRESSURE TROUGH DEVELOPING OVER THE WEST WILL SEND A
SERIES OF WEATHER SYSTEMS INTO SOUTHERN CALIFORNIA NEXT
WEEK...BRINGING PERIODS OF RAIN AND MOUNTAIN SNOW AT TIMES.

THE FIRST CHANCE OF PRECIPITATION WILL BE THIS WEEKEND AS THE MARINE
LAYER RAPIDLY DEEPENS...THOUGH MOST RAINFALL AMOUNTS SHOULD BE LESS
THAN ONE-QUARTER INCH. MORE SIGNIFICANT PRECIPITATION IS EXPECTED
MONDAY WHEN A STRONG WAVE ASSOCIATED WITH THE LOW PRESSURE SYSTEM
MOVES THROUGH THE AREA. ANOTHER WAVE COULD BRING MORE PRECIPITATION
TUESDAY NIGHT OR WEDNESDAY. GIVEN THE MOIST PATTERN...SHOWERS COULD
OCCUR AT ALMOST ANYTIME NEXT WEEK. THE WEATHER WILL ALSO BE MUCH
COOLER THAN DURING RECENT WEEKS.

PRELIMINARY RAINFALL ESTIMATES THROUGH THE MIDDLE OF NEXT WEEK RANGE
FROM ABOUT ONE TO TWO INCHES WEST OF THE MOUNTAINS...TWO TO FOUR
INCHES ON THE WEST FACING MOUNTAIN SLOPES AND A HALF-INCH TO ONE
INCH IN THE DESERTS. HOWEVER...IN ANY OF THESE AREAS...LOCALLY
HEAVIER RAINFALL COULD OCCUR.

SNOW LEVELS WILL START OUT ABOVE 7000 FEET SATURDAY AND THEN
GRADUALLY LOWER TO 4000 TO 5000 FEET BY MONDAY. SNOW LEVELS BETWEEN
4000 AND 5000 FEET WILL CONTINUE THROUGH THURSDAY...THOUGH IT COULD
GET LOCALLY LOWER...ESPECIALLY TUESDAY NIGHT OR WEDNESDAY. THERE
COULD BE ONE TO TWO FEET OF SNOW AT THE HIGHER ELEVATIONS OF THE SAN
BERNARDINO AND RIVERSIDE COUNTY MOUNTAINS WITH UP TO ONE FOOT IN
HIGHER PARTS OF THE SAN DIEGO COUNTY MOUNTAINS. SEVERAL INCHES OF
SNOW COULD FALL ON THE PEAKS OF THE SANTA ANA MOUNTAINS.
SNOW...BLOWING SNOW AND DENSE FOG WILL MAKE TRAVEL HAZARDOUS THROUGH
THE MOUNTAINS DURING THIS PERIOD.

PERIODS OF HEAVY RAIN WILL INCREASE THE FLASH FLOOD POTENTIAL.
RESIDENTS LIVING IN AND BELOW RECENTLY BURNED AREAS SHOULD BE
PREPARED FOR POSSIBLE FLASH FLOODING AND DEBRIS FLOW. PEOPLE
PLANNING OUTDOOR ACTIVITIES SHOULD MONITOR THE LATEST WEATHER
FORECASTS.
