AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
245 AM PST SAT DEC 16 2006

.SYNOPSIS...A WINTER STORM APPROACHING FROM THE PACIFIC WILL BRING
VERY COOL AND WINDY WEATHER THIS WEEKEND. RAIN WILL OCCUR AT TIMES
AT LOWER ELEVATIONS WITH SNOW IN THE MOUNTAINS AND EVEN INTO THE
HIGH DESERTS. THE HEAVIEST PRECIPITATION WILL OCCUR THIS
EVENING...THOUGH SOME SHOWERS COULD OCCUR ANYTIME TODAY THROUGH
SUNDAY NIGHT. BEHIND THE SYSTEM...STRONG GUSTY WINDS WILL DEVELOP
THROUGH AND BELOW PASSES AND CANYONS MONDAY THROUGH TUESDAY...BUT IT
WILL REMAIN QUITE CHILLY UNTIL MID WEEK...AND THE WARMING TREND WILL
RETURN TEMPERATURES TO NEAR OR A LITTLE ABOVE NORMAL BY LATE WEEK.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES.

SKIES WERE MOSTLY CLOUDY AS HIGH CLOUDS ASSOCIATED WITH THE JET WERE
FLYING OVER...AND LOW CLOUDS WERE WIDESPREAD W OF THE MTNS DUE TO A
RAPIDLY DEEPENING MARINE LAYER. MOSTLY OROGRAPHIC PRECIP IS EXPECTED
TODAY DUE TO THE DEEP MARINE LAYER AND ASSOCIATED MOIST LAYER AROUND
850 MB AND INCREASING W-SW WINDS...BETWEEN 15 AND 35 KNOTS AT 850 MB
AND UP TO 50 KNOTS AT 700 MB. WITH WINDS LIKE THAT...SOME PRETTY
STRONG WIND GUSTS...LOCALLY EXCEEDING 50 MPH...WILL OCCUR ALONG THE
MTN CRESTS AND ON THE E/NE SLOPES OF THE MTNS. THUS...A WIND
ADVISORY WILL BE IN EFFECT FOR THE MTNS/DESERTS FROM 9 AM TO 9 PM.

SATELLITE INDICATES A GOOD FRONT ABOUT 250 MILES W OF PT CONCEPTION
ALONG WITH GOOD UPPER-LEVEL DIFFLUENCE. THE FRONT SHOULD HOLD
TOGETHER AND MOVE THROUGH OUR AREA PROBABLY EARLY THIS EVENING AND
BRING A QUICK SHOT OF SOME MODERATE TO HEAVY RAIN. THIS WILL ALSO BE
WHEN THE SNOW LEVELS COME CRASHING DOWN FROM ABOUT 6000 FEET TODAY
TO 3000 FEET OVERNIGHT. A SNOW ADVISORY MAY BE NEEDED
TONIGHT...THOUGH POST-FRONTAL SNOWFALL AMOUNTS MAY NOT BE THAT
GREAT. REGARDLESS...I-15 THROUGH THE CAJON PASS WILL PROBABLY BE
AFFECTED. TOTAL SNOW AMOUNTS WILL MOSTLY BE A FEW INCHES...BUT LOCAL
AMOUNTS GREATER THAN 6 WILL BE POSSIBLE...MAINLY ON THE COASTAL MTN
SLOPES ABOVE ABOUT 5500 FEET. THERE WILL BE A LOT OF COLD AIR
ALOFT...SO THUNDERSTORMS WILL BE POSSIBLE...AND THESE COULD PRODUCE
WATERSPOUTS AT THE COAST AND HAIL INLAND. THE UPPER LOW WILL CLOSE
OFF SUNDAY...BUT MODELS HAVE HAD LITTLE CONSISTENCY...EITHER BETWEEN
DIFFERENT MODELS OR OF THE SAME MODEL BETWEEN DIFFERENT RUNS. THE
MOST LIKELY SCENARIO IS FOR SHOWERS TO GRADUALLY TAPER OFF SUNDAY AS
DRY AIR STARTS TO MOVE IN FROM THE NORTH/NORTHWEST. HOWEVER...SOME
MOISTURE COULD WRAP AROUND THE EAST AND EVENTUALLY NORTH SIDE OF THE
LOW SUNDAY NIGHT/MONDAY IF IT LINGERS.

REGARDING RAINFALL...MOST OF IT WILL COME WITH THE FRONT EARLY
TONIGHT. SO AMOUNTS WILL GENERALLY RANGE FROM ONE-THIRD TO ONE-HALF
INCH AT THE COAST WITH LOCAL AMOUNTS OVER ONE INCH ON OROGRAPHIC
WEST OR SW FACING MTN SLOPES. SOUTHERN AREAS...LIKE SAN DIEGO
COUNTY...COULD POTENTIALLY RECEIVE MORE PRECIP THAN NORTHERN AREAS
GIVEN THE SPLITTING STORM W OF PT CONCEPTION AND A TURN TOWARDS MORE
W VERSUS SW FLOW ALOFT WITH THE FRONT. THE DESERTS WILL MOSTLY HAVE
LESS THAN ONE-QUARTER INCH AS THE MOISTURE DOES NOT LOOK AS DEEP AS
IT DID WITH PREVIOUS RUNS.

THE TIMING OF THE DEPARTURE OF THE SYSTEM IS UNCERTAIN...AND THUS
THE TIMING OF THE STRONG OFFSHORE FLOW TOO IS UNCERTAIN. AT THIS
TIME...BOTH MONDAY AND TUESDAY LOOK QUITE WINDY THROUGH/BELOW PASSES
AND CANYONS...AND FUTURE SHIFTS MAY WANT TO CONSIDER A HIGH WIND
WATCH FOR SOME AREAS LIKE THE INLAND EMPIRE...SAN BERNARDINO COUNTY
MTNS AND SANTA ANA MTNS. SUNDAY/MONDAY HAVE THE COLDEST PROFILE
ALOFT...SO MOST LOWER ELEVATIONS WILL PROBABLY BE STUCK IN THE 50S.
SLIGHT WARMING IS EXPECTED TUE/WED BEFORE A RIDGE FORMING OVER THE E
PAC BRINGS BETTER WARMING...TO LEVELS AT OR A BIT ABOVE
NORMAL...LATE IN THE WEEK. OFFSHORE FLOW COULD GET STRONG AGAIN LATE
IN THE WEEK TOO.

&&

.AVIATION...
MARINE LAYER RISING RAPIDLY AND SEEMS TO BE ABOUT 3000 TO 3500 FT
EARLY THIS MORNING. EXPECT IT TO BLOW BY 4000 FT LATE THIS MORNING
AND BE UP NEAR 5K FT THIS AFTERNOON. BASES THIS MORNING AROUND 2000
TO 2500 FEET MSL. EXPECT STRATUS TO BE MOSTLY INTACT WITH SOME
BREAKS THROUGH TODAY. SOME DRIZZLE OR LIGHT RAIN IS EXPECTED FROM
THE MARINE LAYER THIS MORNING AND AFTERNOON AS STRONG FRONT
APPROACHES. FRONT EXPECTED TO MAKE LANDFALL ABOUT 00Z-02Z IN ORANGE
COUNTY AND A COUPLE OF HOURS LATER IN SAN DIEGO COUNTY...SPREADING
INLAND OVER NIGHT. HEAVIEST RAIN EXPECTED TONIGHT. THUNDERSTORMS
POSSIBLE TONIGHT THROUGH SUNDAY. BASES AND VIS EXPECTED TO LOWER TO
IFR CONDITIONS IN HEAVY RAIN AND FOG TONIGHT. WINDS AT 5K FT...
SOUTHWEST 15-20 KT...BECOMING WEST 20-25 KT AFTERNOON...THEN
SOUTHWEST TO WEST 25-30 KT TONIGHT...DROPPING TO 10-15 KT SUN
MORNING. WINDS AT 10K FT...SOUTHWEST TO WEST 35-45 KT THROUGH
AFTERNOON...BECOMING 40-50 KT TONIGHT...DROPPING TO 15-25 KT SUN
MORNING.

.MARINE...
A LARGE NW SWELL WITH 14 SEC PERIOD WILL INCREASE TODAY WITH A
SLIGHT INCREASE SUNDAY. A STRONG COLD FRONT WILL MOVE INTO THE
COASTAL WATERS LATE THIS AFTERNOON OR EVENING. THUNDERSTORMS
POSSIBLE TONIGHT THROUGH SUNDAY ALONG WITH WATERSPOUTS. WINDS WILL
INCREASE TODAY THROUGH TONIGHT AS THE TROUGH DEEPENS OVER THE AREA
AND THE COLD FRONT MOVES THROUGH. THIS WILL GENERATE HAZARDOUS SEAS
AND VERY ROUGH CONDITIONS THROUGH THE WEEKEND.
