AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
200 PM PST TUE NOV 29 2011

.SYNOPSIS...
FAIR WEATHER WITH VARIABLE HIGH CLOUDS AND MILD TEMPERATURES WILL
CONTINUE THROUGH TODAY. A BRIEF RETURN OF THE MARINE LAYER TO THE
IMMEDIATE COAST IS EXPECTED FOR WEDNESDAY MORNING...PROVIDING SOME
LOW CLOUDS AND FOG AND KICKING OFF A COOLING TREND FOR THE TEMPS. A
STRONG LOW PRESSURE SYSTEM WILL DIG SOUTH AND EAST OVER SOUTHERN
CALIFORNIA ON THURSDAY BRINGING STRONG NORTHEASTERLY
WINDS...ESPECIALLY TO ORANGE COUNTY...THE INLAND EMPIRE AND THE SAN
BERNARDINO COUNTY MOUNTAINS. MUCH COLDER WEATHER WILL ACCOMPANY THIS
SYSTEM AS WELL...ALONG WITH A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS THURSDAY AND FRIDAY. SNOW SHOWERS WILL ALSO BE
POSSIBLE IN THE MOUNTAINS. FAIR WEATHER AND LOCALLY GUSTY WINDS FOR
EARLY NEXT WEEK AS BRIEF HIGH PRESSURE RETURNS.

&&

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

WATER VAPOR IMAGERY SHOW AN IMPRESSIVE UPPER LEVEL LOW MOVING INTO
BRITISH COLUMBIA THIS AFTERNOON...HELPING TO FLATTEN THE RIDGE OF
HIGH PRESSURE OVER THE WEST.  A WEAK DISTURBANCE IS ALSO MOVING
THROUGH THE FOUR CORNERS AREA...WHICH WILL OPEN THE DOOR FOR THE
UPPER LEVEL LOW TO DIG SOUTHWARD THROUGH THE INTERMOUNTAIN WEST AND
GREAT BASIN TO THE COLORADO RIVER BASIN OVER THE NEXT 24 TO 36
HOURS.  THIS WILL BRING SIGNIFICANTLY COLDER WEATHER TO THE
REGION...WITH TEMPERATURES FALLING 10 TO 20 DEGREES BELOW NORMAL FOR
THURSDAY AND FRIDAY.

THE MAIN STORY OVER THE NEXT FEW DAYS THOUGH WILL BE WITH THE
WINDS.  SURFACE GRADIENTS BETWEEN SAN DIEGO AND TONOPAH WILL
INCREASE SIGNIFICANTLY WEDNESDAY EVENING TO BETWEEN 15 AND 17
MBS...AND HOLD STEADY THROUGH THE WEEKEND.  UPPER LEVEL WIND SUPPORT
ALSO SHOWS 925 AND 850 WINDS INCREASING TO 60 TO 75 KNOTS WEDNESDAY
NIGHT...WHICH FAVORS WIND GUSTS UP TO 70 MPH...WITH LOCAL GUSTS UP
TO 85 MPH THROUGH AND BELOW THE FAVORED CANYONS AND PASSES.  AS A
RESULT...WILL ISSUE A HIGH WIND WARNING FOR THE SAN BERNARDINO AND
RIVERSIDE MOUNTAINS AS WELL AS THE INLAND EMPIRE...THE SANTA ANA
FOOTHILLS...AND ORANGE COUNTY.  ALSO ISSUED HIGH WIND FOR THE SAN
DIEGO MOUNTAINS...TIMING THINGS A LITTLE LATE WEDNESDAY NIGHT.
ELSEWHERE THOUGH...WINDS WILL DEFINITELY BE IN WIND ADVISORY
CRITERIA...AND MAY FLIRT WITH WARNING CRITERIA.  THEREFORE...A WATCH
HAS BEEN ISSUED FOR THE OTHER AREAS.

THERE WILL ALSO BE PLENTY OF COLD AIR ACCOMPANYING THIS SYSTEM...AS
850 MB TEMPERATURES FALL TO AROUND OR BELOW 0 DEGREES AND 700 MB
TEMPERATURES FALL AROUND -10 DEGREES.  THIS MEANS THAT DAYTIME
TEMPERATURES WILL FALL 10 TO 20 DEGREES BELOW NORMAL FOR THURSDAY
AND FRIDAY.  THERE IS STILL QUITE A BIT OF UNCERTAINTY WITH THIS
SYSTEM...AS TO WHETHER OR NOT THERE WILL BE ENOUGH MOISTURE TO BRING
SHOWERS AND THUNDERSTORMS TO THE REGION.  BOTH THE 12Z GFS AND ECMWF
ARE SUGGESTING A BAND OF PRECIPITATION DEVELOPING OVER THE
REGION...SO HAVE INCLUDED A CHANCE OF SHOWERS AND MOUNTAIN SNOW
SHOWERS AS WELL AS A SLIGHT CHANCE OF THUNDERSTORMS.  IF THESE
SOLUTIONS PAN OUT...SNOW LEVELS COULD FALL SIGNIFICANTLY...DOWN TO
AROUND 3000 FEET...AND MAY BE LOCALLY LOWER WITH THE HEAVIER
SHOWER.  THAT MEANS A FEW INCHES OF SNOW COULD BE POSSIBLE IN THE
MOUNTAINS.  FOR NOW THOUGH...THE MODELS ARE STILL STRUGGLING WITH
THIS...SO CONFIDENCE IS QUITE LOW.

MOST MODELS SOLUTIONS HAVE THE CLOSED LOW MOVING EAST OUT OF THE
AREA OVER THE WEEKEND...WITH OFFSHORE FLOW CONTINUING TO BRING SOME
GUSTY WINDS BELOW PASSES AND CANYONS.  TEMPS WILL ALSO BE A LITTLE
LESS COLD...BUT STILL BELOW NORMAL.  HOWEVER...THE 12Z RUN OF THE
ECMWF AND THE GEM INDICATE A SECOND SHORTWAVE MOVING INTO THE BASE
OF THE MEAN TROUGH...KEEPING A CLOSED LOW OVER SOUTHERN CALIFORNIA
THROUGH NEXT TUESDAY.  IF THIS VERIFIES...EXPECT TEMPERATURES TO
REMAIN WELL BELOW SEASONAL AVERAGES THROUGH EARLY NEXT WEEK...WITH
OFFSHORE FLOW CONTINUING.

&&

.AVIATION...
292150Z...VARIABLE HIGH CLOUDS BASED AT OR ABOVE 25000 FEET
MSL...WITH MAINLY UNRESTRICTED VISIBILITIES THROUGH THIS EVENING.
AFTER 10Z A SHALLOW MARINE LAYER WITH BASES 100-400 FEET MSL...TOPS
AROUND 700 FEET MSL...AND VISIBILITIES BELOW 3 MILES WILL FORM OVER
THE COASTAL WATERS. THE PATCHY LOW CLOUDS AND FOG MAY SPREAD FAR
ENOUGH INLAND TO IMPACT KSAN BETWEEN 10Z AND 18Z WEDNESDAY MORNING.
STRONG GUSTY NORTHEAST WINDS WITH STRONG UP AND DOWNDRAFTS AND WIND
SHEAR IS POSSIBLE WEDNESDAY EVENING THROUGH EARLY AFTERNOON FRIDAY.

&&

.FIRE WEATHER...
A VERY COLD AND STRONG UPPER LEVEL LOW WILL DIG SOUTH THROUGH THE
GREAT BASIN AND THE COLORADO RIVER BASIN ON WEDNESDAY THROUGH
FRIDAY...BRINGING VERY STRONG AND GUSTY NORTH TO NORTHEAST WINDS TO
SOUTHERN CALIFORNIA LATE WEDNESDAY EVENING THROUGH FRIDAY.  NORTH TO
NORTHEAST WIND GUSTS UP TO 70 MPH WILL BE POSSIBLE...WITH LOCAL
GUSTS UP TO 85 MPH THROUGH AND BELOW THE FAVORED CANYONS AND
PASSES.  THEREFORE...HAVE ISSUED A FIRE WEATHER WATCH.
HOWEVER...HUMIDITIES MAY BE MARGINAL AT BEST...AND GIVEN THAT THE
TRACK OF THIS SYSTEM COULD BRING SOME SHOWERS...SNOW SHOWERS...AND
THUNDERSTORMS TO THE REGION AS WELL ON THURSDAY AND FRIDAY.  WINDS
WILL DECREASE ON FRIDAY...BUT REMAIN LIGHTLY OFFSHORE THROUGH THE
WEEKEND.

...VERY STRONG AND GUSTY WINDS...COLDER TEMPERATURES...AND THE
POTENTIAL FOR UNSETTLED WEATHER RETURNING WEDNESDAY NIGHT THROUGH
FRIDAY...

A VERY STRONG AND UNSEASONABLY COLD TROUGH OF LOW PRESSURE WILL
DIG OVER THE GREAT BASIN AND LOWER COLORADO RIVER BASIN WEDNESDAY
INTO THURSDAY...BRINGING SIGNIFICANTLY COLDER WEATHER TO THE
REGION AS WELL AS VERY STRONG AND GUSTY WINDS. THERE IS EVEN THE
POTENTIAL FOR SOME SHOWERS AND THUNDERSTORMS TO DEVELOP ON
THURSDAY AND FRIDAY...WITH SNOW LEVELS POSSIBLY FALLING INTO THE
FOOTHILLS WITH SOME OF THE STRONGER SHOWERS.

WINDS...
STRONG AND GUSTY NORTH TO NORTHEAST WINDS WILL DEVELOP WEDNESDAY
EVENING AND CONTINUE THROUGH FRIDAY...AS STRONG OFFSHORE FLOW
DEVELOPS AROUND THE NORTHWEST SIDE OF THE SYSTEM. STRONGEST WINDS
WILL MOST LIKELY BE IN ORANGE COUNTY...THE INLAND EMPIRE AND
THE SAN BERNARDINO COUNTY MOUNTAINS...WHERE WIND GUSTS COULD
EXCEED 70 MPH AT TIMES...ESPECIALLY THROUGH AND BELOW PASSES AND
CANYONS. STRONG WINDS ARE ALSO LIKELY IN THE APPLE AND LUCERNE
VALLEYS. DUE TO THE UNCERTAINTY OF THE POSITION OF THE UPPER
LOW...STRONG WINDS ARE LESS CERTAIN IN SAN DIEGO COUNTY...BUT ARE
STILL POSSIBLE. STRONGEST WINDS ARE EXPECTED LATE WEDNESDAY NIGHT
AND THURSDAY...WHEN DAMAGE TO TREES AND POWER LINES MAY OCCUR.
TRAVEL WILL BE DIFFICULT...ESPECIALLY FOR HIGH PROFILE VEHICLES.

TEMPERATURES...
MUCH COLDER AIR WILL FILTER INTO SOUTHERN CALIFORNIA ON
THURSDAY...ESPECIALLY IN THE MOUNTAINS AND HIGH DESERTS. HIGHS
WILL MOSTLY BE IN THE 30S AND 40S IN THE MOUNTAINS...WHICH WILL BE
15 TO 20 DEGREES BELOW NORMAL. IN THE APPLE AND LUCERNE
VALLEYS...HIGHS WILL STRUGGLE TO REACH 50. WIND CHILL READINGS
MAY ALSO BE IN THE TEENS IN COLDEST PARTS OF THE SAN BERNARDINO
MOUNTAINS THURSDAY. MOST VALLEY AND COASTAL AREAS WILL STRUGGLE TO
WARM INTO THE LOWER TO MID 60S. LITTLE OR NO WARMING IS EXPECTED
FRIDAY...THOUGH WIND SPEEDS WILL DECREASE SOMEWHAT.

SHOWERS AND THUNDERSTORMS...
THERE IS A SMALL CHANCE OF SHOWERS AND THUNDERSTORMS THURSDAY
THROUGH FRIDAY...ESPECIALLY OVER HIGHER TERRAIN. PRECIPITATION
AMOUNTS ARE STILL HIGHLY UNCERTAIN...AND WILL DEPEND ON THE TRACK
OF THE UPPER LOW...WITH MOST AREAS SEEING LIGHT AMOUNTS. SNOW
LEVELS WILL LIKELY BE LOW...FALLING TO 3500 TO 4000 FEET.
HOWEVER...LOCALLY LOWER SNOW LEVELS WILL BE POSSIBLE ON THE NORTH
SLOPES OF THE SAN BERNARDINO MOUNTAINS...AND WITH THE HEAVIER
SHOWERS. A FEW INCHES OF SNOW COULD FALL IN THE MOUNTAINS.

OUTLOOK...
THE PRECIPITATION WILL END BY FRIDAY NIGHT. HOWEVER...OFFSHORE
FLOW WILL CONTINUE TO BRING LOCALLY GUSTY WINDS THROUGH THE
WEEKEND...BUT AT LOWER SPEEDS THAN ON THURSDAY AND FRIDAY.

PEOPLE WITH OUTDOOR INTERESTS SHOULD MAINLY BE PREPARED FOR THE
STRONG GUSTY WINDS AND COLDER WEATHER WEDNESDAY NIGHT THROUGH FRIDAY.
