AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
900 AM PDT TUE OCT 17 2006

.SYNOPSIS...AN UPPER LEVEL TROUGH IS MOVING EAST ACROSS THE REGION
TODAY. A DRY COLD FRONT WILL BRING CLEARING THIS AFTERNOON. A RAPID
SHIFT TO OFFSHORE FLOW IS EXPECTED TONIGHT AS HIGH PRESSURE BUILD
OVER THE GREAT BASIN. WEAK TO MODERATE SANTA ANA WINDS ARE POSSIBLE
BY WEDNESDAY MORNING. OFFSHORE FLOW AND VERY DRY CONDITIONS ARE
EXPECTED TO CONTINUE THROUGH FRIDAY...AND A FIRE WEATHER WATCH IS IN
EFFECT.

&&

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

FAIRLY DEEP MARINE LAYER THIS MORNING AHEAD OF A WEAK COLD FRONT
MOVING SOUTHEAST THROUGH THE AREA. MORNING TOP REPORTS RANGED FROM
AROUND 4000 FEET NEAR THE COAST TO AROUND 5000 FEET INLAND WITH
STRATOCUMULUS REACHING WELL INLAND TO THE COASTAL SLOPES OF THE
MOUNTAINS. SATELLITE WATER VAPOR LOOP INDICATES THE TROUGH AXIS WAS
PASSING THROUGH THIS MORNING AND CLEARING IS BEGINNING TO TAKE PLACE
FROM THE NORTHWEST.

12Z NAM MODEL INDICATES SOME CYCLONIC FLOW REMAINS OVER THE AREA
THROUGH WEDNESDAY MORNING AND KEEPS THE MARINE LAYER FAIRLY DEEP
THROUGH THIS EVENING BEFORE DRYING MOVES IN FROM THE NORTH LATE
TONIGHT AND WEDNESDAY MORNING. PATTERN APPEARS FAVORABLE FOR A
NORTHWEST WIND PATTERN THROUGH THE THIS EVENING THEN SHIFTS AROUND
TO THE NORTH LATE TONIGHT INTO WEDNESDAY. EXPECT WIND ADVISORY LEVEL
WINDS IN THE USUAL WINDY AREAS AND POSSIBLY HIGH WIND WARNING LEVEL
WINDS IN THE INLAND EMPIRE BELOW THE CAJON PASS AND POSSIBLY THROUGH
THE SANTA ANA CANYON AREA. WILL SEE WHAT THE 12Z GFS INDICATES
BEFORE DECIDING. PLAN TO ISSUE WITH AFTERNOON PACKAGE. WIND PEAKS
WEDNESDAY MORNING BUT REMAINS WINDY THROUGH THURSDAY.

RIDGING OVER THE EASTERN PACIFIC REMAINS IN PLACE THROUGH THE
WEEKEND WITH A DRY NORTHERLY FLOW ALOFT ALONG THE WEST COAST. THE
06Z GFS PICKS UP ON A WEAK CUT OFF LOW SOUTHWEST OF THE SOUTHERN
CALIFORNIA COAST ON THE WEEKEND AND SWINGS THAT LOW NORTHEAST ACROSS
SOUTHERN CALIFORNIA NEXT MONDAY. IF THIS IS CORRECT...THIS LOW COULD
BRING SOME SHOWERS TO THE AREA ON MONDAY. GIVEN THIS IS A CUT OFF
LOW AND TIMING WILL BE DIFFICULT...WILL NOT JUMP ON THIS AT THIS
TIME BUT WAIT AND SEE WHAT LATER MODEL RUNS DO.

NO UPDATES ARE PLANNED AT THIS TIME.

&&

.AVIATION...
MOST AIRFIELDS SHOULD SCATTER OUT RATHER QUICKLY THIS MORNING AS 30
TO 40 KT NW FLOW AND COLD AIR ADVECTION ABOVE THE MARINE LAYER
WEAKENS THE MARINE INVERSION. ACARS SOUNDINGS INDICATES THE FLOW IS
ALREADY VEERING NORTHERLY ABOVE 5K FT AND ERODING THE INVERSION AT
KSNA...KLAX...AND KONT. THIS TREND SHOULD CONTINUE THE REST OF TODAY
RESULTING IN THE CONTINUED ERODING OF THE STRATUS. EVEN WITH MORE
CLEARING TODAY...EXPECT CEILINGS FROM 4K TO 5K FT AND ISOLATED 1K TO
2K FT CEILINGS THIS MORNING. TOPS ARE AROUND 5K FT AND LOWERING.
SURFACE HEATING WILL RESULT IN SOME SHALLOW SCU THROUGH THIS
AFTERNOON BEFORE DRIER AIR AND OFFSHORE FLOW REPLACES THE MARINE
LAYER TONIGHT. AREAS OF WEST OR NORTHWEST WINDS AT 25KT WITH GUSTS
ABOVE 35KT IN THE MOUNTAINS ARE ALSO EXPECTED TODAY...VEERING NORTH
TO NORTHEAST BY TOMORROW MORNING.
