SATURDAY AFTERNOON. THE STRONGEST WINDS WILL BE OVER THE MOUNTAINS
AND DESERTS WHERE GUSTS COULD EXCEED 45 MPH.

THE LOW MOVES EAST ON SUNDAY AND SKIES BEGIN TO CLEAR AND
TEMPERATURES RECOVER TO NEAR SEASONAL AVERAGES.

STRONG HIGH PRESSURE ALOFT WILL BUILD OVER THE STATE MONDAY THROUGH
WEDNESDAY BRINGING FAIR AND WARM WEATHER. OFFSHORE PRESSURE
GRADIENTS COULD BE STRONG ENOUGH TO CAUSE STRONG GUSTY NORTHEAST
WINDS MAINLY TUESDAY AND WEDNESDAY MORNINGS IN AND BELOW CANYONS AND
PASSES.

A LOW PRESSURE TROUGH APPROACHING FROM THE NW WILL WEAKEN THE HIGH
PRESSURE RIDGE ON THURSDAY AND FRIDAY. THIS WILL BRING LOWER TEMPS
AND INCREASED CLOUDS.

&&

.AVIATION...
291430Z...MOSTLY CLEAR AND VFR CONDITIONS ARE EXPECTED THROUGH THIS
EVENING EXCEPT FOR SCT CIRRUS AROUND FL200. CLOUD LAYERS AROUND 1500

THROUGH SATURDAY...ESPECIALLY IN SOUTHERN SAN DIEGO COUNTY. BREAKERS
WILL RANGE FROM 4 TO 6 FEET WITH A FEW HIGHER SETS.

&&

FIRE WEATHER...
CRITICAL FIRE WEATHER PATTERN TODAY WITH DRY AIR MASS STILL IN PLACE

LOCATIONS THROUGH SUNSET TODAY. RIDGE LEVEL WINDS INCREASING TO 25
TO 35 MPH BY MID AFTERNOON AND +40 MPH BY THIS EVENING. LINGERING

+50 MPH POSSIBLE THROUGH AND BELOW ALIGNED DRAINAGES IN SAN
GABRIEL/SAN BERNARDINO MTNS AND OVER FIRE WEATHER ZONE CAZ260...
VICTOR VALLEY...APPLE VALLEY...LUCERNE VALLEY...JOHNSON VALLEY.
MODEL GUIDANCE INDICATES COLD FRONT ALONG WITH ANY SIGNIFICANT
INCREASE IN RELATIVE HUMIDITY AND WETTING RAINS MAY NOT REACH SW SAN
BERNARDINO/ORANGE COUNTY UNTIL AFTER MIDNIGHT/EARLY MORNING HOURS
SATURDAY.

NEXT CRITICAL FIRE WEATHER PATTERN FORECAST FOR SUNDAY NIGHT  INTO
WEDNESDAY MORNING AS STRONG HIGH PRESSURE BUILDS SURFACE AND ALOFT
OVER GREAT BASIN. AS WITH PREVIOUS SANTA ANA WIND EVENTS THIS
FALL...A SUPPORTIVE UPPER AIR PATTERN DOES NOT APPEAR TO BE PRESENT
SO ONLY A MODERATE EVENT IS EXPECTED...WITH SURFACE PRESSURE
GRADIENTS STRONG ENOUGH TO GENERATE GUSTS +50 MPH WIND PRONE
