AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
930 AM PDT TUE OCT 14 2008

.SYNOPSIS...
STRONG SANTA ANA WINDS WILL CONTINUE TODAY...THEN DECREASE TONIGHT
AND WEDNESDAY. WARM DRY WEATHER WITH CONTINUE TODAY THROUGH
FRIDAY. ONSHORE FLOW WILL BRING COOLING THIS WEEKEND.

&&

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

SURFACE HIGH PRESSURE OVER THE GREAT BASIN WILL MAINTAIN MODERATE TO
STRONG SANTA ANA WINDS THIS MORNING BEFORE WEAKENING THIS AFTERNOON.
NORTHERLY PRESSURE GRADIENTS ARE SLIGHTLY WEAKER THAN 24 HOUR AGO
WITH -7 MB SAN-DAG...BUT SLIGHTLY STRONGER IN THE EAST-WEST
DIRECTION WITH -3 MB SAN-IPL. THE 12Z KNKX SOUNDING SHOWED 30-35 KT
NORTHEAST FLOW BETWEEN 3500-9000 FT AND CONSIDERABLE WARMING BETWEEN
THE SURFACE AND 450 MB. EXPECT WINDS IN THE INLAND EMPIRE AND SANTA
ANA MOUNTAINS TO BE WEAKER THAN YESTERDAY BUT STRONGER IN THE SD AND
RIV COUNTY MOUNTAINS AND FOOTHILLS. AS OF 8 AM...ISOLATED GUSTS IN
EXCESS OF 60 MPH HAD BEEN MEASURED IN THE NORTHERN AREAS WHILE GUSTS
IN EXCESS OF 55 MPH HAD BEEN MEASURED IN THE SD MOUNTAINS NEAR THE
SHOCKEY FIRE. WINDS OF THIS STRENGTH WILL PERSIST THROUGH THE
MORNING...THEN DECREASE DURING THE AFTERNOON/EVENING AS SURFACE HIGH
PRESSURE WEAKENS AND UPPER LEVEL SUPPORT MOVES EAST. THE COMBINATION
OF LOW HUMIDITY AND GUSTY WINDS WILL CONTINUE A HIGH FIRE DANGER.
MAX TEMPS ARE EXPECTED TO BE SEVERAL DEGREES WARMER TODAY WITH
WIDESPREAD 80S WEST OF THE MOUNTAINS.

WEAK OFFSHORE GRADIENTS CONTINUE WED THROUGH FRI...HOWEVER WINDS
WILL GENERALLY NOT BE AN ISSUE. THERE COULD BE A FEW GUSTS TO 25 MPH
EARLY WED MORNING BELOW THE EAST-WEST CANYONS...BUT THAT SHOULD BE
THE LAST OF THE GUSTY WINDS. A TROUGH OF LOW PRESSURE WILL PASS BY
TO OUR NORTH AND HEIGHTS MAY DECREASE SOME...HOWEVER WEAK OFFSHORE
FLOW WILL PERSIST IN THE LOW LEVELS RESULTING IN ADDITIONAL WARMING.
850 MB TEMPS ARE EXPECTED TO PEAK AT 20-21C WED-FRI AND HIGHS SHOULD
EASILY CLIMB INTO THE 90S WEST OF THE MOUNTAINS. IT WILL EVEN BEGIN
TO WARM UP IN THE MOUNTAINS...HOWEVER OVERNIGHT LOWS WILL REMAIN
COLD DUE TO THE DRY AIR IN PLACE. COASTAL AREAS SHOULD BEGIN TO
EXPERIENCE COOLING FROM THE SEA BREEZE BY FRIDAY...AND PATCHY DENSE
FOG COULD FORM AT THE BEACHES AS WE SLOWLY TRANSITION FROM OFFSHORE
TO ONSHORE FLOW.

A WEAK TROUGH MOVING INTO THE WEST WILL BRING COOLER WEATHER AND
ONSHORE FLOW THIS WEEKEND WITH TEMPS RETURNING TO SEASONAL AVERAGES.
THE MARINE LAYER WILL CAUSE NIGHT/MORNING LOW CLOUDS AND FOG WEST OF
THE MOUNTAINS.

BIG DIFFERENCES IN THE MODELS FOR THE BEGINNING OF NEXT WEEK WITH
THE ECMWF SHOWING ANOTHER STRONG INSIDE SLIDER DIVING INTO CA WHILE
THE GFS PLACES US BETWEEN A WEAK TROUGH AND A STRONG RIDGE. THE
ECMWF HAS BEEN THE BETTER LONG RANGE PERFORMER AS OF LATE...SO WILL
LEAN EVER SO SIGHTLY TOWARD THE INSIDE SLIDER SOLUTION. WILL HOLD
OFF ON ANY BIG CHANGES UNTIL MODELS BEGIN TO CONVERGE ON A SOLUTION.

&&

.AVIATION...
141630Z...CLEAR EXCEPT FOR LOCAL BLOWING DUST AND SAND INLAND
VALLEYS AND LOWER DESERTS THIS MORNING. ALSO LOCAL VISIBILITY
OBSCURATIONS FROM SMOKE.

MODERATE TO LOCALLY STRONG SANTA ANA WINDS THIS MORNING...MAINLY
MOUNTAINS AND LOCALLY BELOW CANYONS AND PASSES VALLEY AREAS WITH
STRONG UP AND DOWN DRAFTS. LOW LEVEL WIND SHEAR POSSIBLE ELSEWHERE.

OFFSHORE FLOW WEAKENS THIS AFTERNOON WITH THE SEA BREEZE RETURNING
TO THE COAST IN THE AFTERNOON. SANTA ANA WINDS WILL RETURN
TONIGHT AND WEDNESDAY MORNING. THEY WILL BE WEAKER...AND MAINLY IN
THE MOUNTAINS AND LOCALLY BELOW THE PASSES.

&&

.FIRE WEATHER...
UPPER LEVEL LOW PRESSURE OVER THE SOUTHERN ROCKIES AND SURFACE HIGH
PRESSURE OVER THE GREAT BASIN WILL COMBINE TO CONTINUE PERIODS OF
MODERATE TO LOCALLY STRONG SANTA ANA WINDS AT TIMES THROUGH THIS
AFTERNOON...IN ADDITION TO PROLONGED PERIODS OF LOW RELATIVE
HUMIDITIES WITH VERY LITTLE OVERNIGHT RECOVERY THROUGH WEDNESDAY.

THE MOST WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS WILL BE THIS
AFTERNOON WHEN THE OFFSHORE WINDS WILL BE AT THEIR STRONGEST. THIS
MORNING...WINDS ARE MOSTLY 15 TO 25 MPH GUSTING TO 45 MPH BUT IN THE
MOST FAVORED LOCATIONS GUSTS OF 55 TO 65 MPH HAVE BEEN REPORTED.
WIND SPEEDS ARE EXPECTED TO STEADILY DECREASE THROUGH TONIGHT AND BE
WEAKLY OFFSHORE ON WEDNESDAY.

A RED FLAG WARNING IS CURRENTLY IN EFFECT FOR MOST OF EXTREME
SOUTHWEST CALIFORNIA...EXCLUDING THE DESERTS. THE WARNING HAS BEEN
EXTENDED UNTIL WEDNESDAY NIGHT DUE TO LONG DURATION LOW RELATIVE
HUMIDITIES CONTINUING THROUGH WEDNESDAY ALTHOUGH THE WINDS WILL BE
WEAKER.
