AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
917 PM PST SAT FEB 2 2008

.SYNOPSIS...A POTENT...FAST MOVING WINTER STORM WILL BRING RAIN AND
MOUNTAIN SNOW LATE TONIGHT THROUGH SUNDAY NIGHT. STRONG WINDS
WILL ALSO ACCOMPANY THIS STORM. NEXT WEEK WE GET A BREAK IN THE
WEATHER AS HIGH PRESSURE BUILDS OVER THE WEST...SWINGING US INTO AN
OFFSHORE FLOW PATTERN FOR DRY AND WARMER DAYS.

&&

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

DARKENING IN THE WATER VAPOR IMAGERY JUST OFF THE OREGON COAST
INDICATES THE CORE OF A POWERFUL 180 KT JET. COLD CIRRUS CLOUDS IN
ADVANCE OF THIS FEATURE ARE STREAMING RAPIDLY SE ACROSS CENTRAL CA.
ONSHORE SURFACE PRESSURE GRADIENTS ARE INCREASING TO THE GREAT BASIN
AND WINDS ARE SLOWLY RESPONDING IN SOME MOUNTAIN AREAS WITH GUSTS
LOCALLY INTO THE 25 TO 30 RANGE. THE 00Z MIRAMAR SOUNDING SHOWS OUR
MOIST LAYER EXTENDS TO ABOUT 4500 FT WITH JUST OVER 1/2 INCH OF
PRECIPITABLE WATER.

THE STRONG JET OFF THE PACNW COAST WILL AMPLIFY A DEEP UPPER TROUGH
OVER THE WESTERN STATES AND RAMP UP PRESSURE GRADIENTS TO THE
INTERIOR AS A STRONG SURFACE LOW DEVELOPS AND TRACKS TOWARD THE
OKLAHOMA PANHANDLE SUNDAY NIGHT. THIS WILL CREATE A LOT OF WIND FOR
US...ESPECIALLY IN THE MOUNTAINS AND DESERTS WHERE HIGH WIND
WARNINGS WILL BE NEEDED. GUSTS TO 80 MPH WILL BE POSSIBLE IN THE
WIND PRONE AREAS ON THE DESERT SLOPES OF THE SAN BERNARDINO MTNS...
AND STRONG AND POTENTIALLY DAMAGING GUSTS WILL BE POSSIBLE IN THE
NORTHERN COACHELLA VALLEY AS WELL. IN ADDITION TO THE WIND...THERE
IS A FAIR AMOUNT OF PACIFIC MOISTURE THAT WILL BE DRAWN OVER THE
AREA...SO EVEN THOUGH THIS IS TECHNICALLY AN INSIDE SLIDER...IT
APPEARS THERE WILL BE ENOUGH LIFT AND MOISTURE PRESENT OVER SOCAL
FOR SOME MODERATE TO LOCALLY HEAVY PRECIPITATION AT TIMES FROM SUN
MORNING THOUGH SUN NIGHT.

IT SHOULD BE COLD ENOUGH AT THE HIGHER RESORTS FOR HEAVY SNOW...SO A
WINTER STORM WARNING WILL BE IN EFFECT ON SUN AND SUN NIGHT FOR
THE NORTHERN MOUNTAINS. SINCE THE COLDER AIR WILL ARRIVE IN SAN
DIEGO COUNTY SUNDAY EVENING...THERE IS A GOOD CHANCE THAT SNOWFALL
WILL NOT REACH CRITERIA FOR A WINTER STORM WARNING...HOWEVER A SNOW
AND BLOWING SNOW ADVISORY WILL LIKELY BE NEEDED BY SUN NIGHT WHEN
SEVERAL INCHES OF SNOW WILL COMBINE WITH THE WINDS TO MAKE TRAVEL
HAZARDOUS AT BEST.

THIS SYSTEM SHOULD BE FAR ENOUGH EAST BY MON AFTERNOON TO BRING AN
END TO ALL PRECIPITATION AND WIND DOWN THE WINDS. THE FLOW WILL TURN
NORTHERLY BEHIND THIS SYSTEM USHERING IN A SHOT OF CHILLY AIR. AS
SKIES CLEAR...FROST AND LOCAL FREEZING CONDITIONS WILL BE POSSIBLE
IN SHELTERED AREAS BY TUE MORNING AND AGAIN WED MORNING.

WIND ADVISORIES MAY BE NEEDED AGAIN ON TUE AND WED AS MODERATE TO
LOCALLY STRONG OFFSHORE FLOW DEVELOPS. RIDGING OVER SOCAL WILL HELP
TO KEEP PERIODS OF DRY OFFSHORE FLOW THROUGH THE WEEK. WITH THE
HIGHER HEIGHTS/THICKNESS...IT WILL BE WARMER.

&&

.AVIATION...
030445Z...WEAK INVERSION CONTINUED AROUND 5500 FEET WITH A MOIST
LAYER BETWEEN ABOUT 2500 AND 5500 FEET. SCT-BKN CONDITIONS WITH
BASES AROUND 2500 FEET MSL WILL OCCUR MOST OF THE NIGHT. AS THE
STORM SYSTEM ARRIVES...PRECIP WILL SPREAD FROM THE KSNA/KFUL/KONT
AREAS AROUND 11Z SUN SOUTHEAST TO KSAN/KSDM AROUND 15Z SUN. CIGS
WILL BE VARIABLE...BELOW 1500 FEET MSL AT TIMES...LOCALLY BELOW 1000
FEET MSL. VSBYS AT COASTAL/LOWER VALLEY AIRPORTS WILL DROP 3 MILES
OR LESS AT TIMES SUNDAY. MTN OBSCURATIONS WILL OCCUR. STRONG GUSTY
WINDS WILL OCCUR OVER HIGHER TERRAIN...ESPECIALLY SUNDAY
AFTERNOON/EVENING...WITH LOCAL SURFACE GUSTS OVER 50 KNOTS.
UPDRAFTS/DOWNDRAFTS WILL OCCUR DUE TO MTN WAVE ACTIVITY...AND ROTORS
WILL BE POSSIBLE IN THE COACHELLA VALLEY. WIND GUSTS COULD APPROACH
30 KNOTS AT LINDBERGH FIELD BRIEFLY MID/LATE SUNDAY AFTERNOON.

&&

.MARINE...
WINDS WILL INCREASE FROM THE SOUTHWEST AND WEST SUNDAY INTO MONDAY
MORNING WITH THE PASSAGE OF THE UPPER LEVEL STORM SYSTEM AND
ASSOCIATED COLD FRONT. HOWEVER...SUSTAINED WINDS SHOULD REMAIN
AT/BELOW 30 KNOTS...WHICH IS EASILY BELOW THE MINIMUM GALE FORCE
CRITERIA OF 35 KNOTS FOR A SUSTAINED WIND. SO...A SMALL CRAFT
ADVISORY WILL BE IN EFFECT SUN INTO MON. A SHORT PERIOD WNW SWELL
WILL LOCALLY EXCEED 8 FEET WITH THIS SYSTEM. CONDITIONS WILL IMPROVE
MONDAY.
