..DISCUSSION FROM LOS ANGELES/OXNARD
...WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ACROSS
THE INTERIOR VALLEYS, MOUNTAINS, AND DESERTS THROUGH MIDDLE OF NEXT
WEEK DUE TO GUSTY ONSHORE WINDS, VERY WARM TEMPERATURES, AND LOW
HUMIDITIES...
...SMALL RISK OF AFTERNOON AND EVENING THUNDERSTORMS ACROSS
MOUNTAINS AND DESERT NEXT TUESDAY TO THURSDAY DUE TO MARGINAL
MONSOONAL MOISTURE...
STRONG HIGH PRESSURE ALOFT OVER THE SOUTHWESTERN UNITED STATES HAS
BROUGHT HOT TRIPLE DIGIT TEMPERATURES UP TO 105 DEGREES TODAY ACROSS
PORTIONS OF THE VALLEYS, LOWER MOUNTAINS, AND DESERTS, ALONG WITH
HUMIDITIES IN THE 5 TO 15 PERCENT RANGE. CLOSER TO THE COAST, THE
TEMPERATURES REMAIN MODERATED DUE TO A PERSISTENT ONSHORE FLOW IN
PLACE. TEMPERATURES ABOVE NORMAL FOR THIS TIME OF YEAR WILL LIKELY
EXTEND INTO EARLY NEXT WEEK ACROSS THE INTERIOR AREAS, ESPECIALLY IN
THE ANTELOPE VALLEY. DURING THIS TIME, DAYTIME HIGH TEMPERATURES
ACROSS THE INTERIOR WILL GENERALLY RANGE BETWEEN 95 AND 105 DEGREES,
RESULTING IN ENHANCED MIXING HEIGHTS BETWEEN 8,000 AND 13,000 FEET,
WHICH COULD RESULT IN VERTICAL PLUME ENHANCEMENT OF NEW FIRES,
ESPECIALLY IN THE MOUNTAINS.
WHILE SOME CLOUDS WILL LIKELY DEVELOP ACROSS THE MOUNTAINS AND
ANTELOPE VALLEY DUE TO INCREASED SUB-TROPICAL MOISTURE, A MOSTLY DRY
AIR MASS WILL LIKELY REMAIN IN PLACE CLOSER TO THE SURFACE. MINIMUM
HUMIDITIES BETWEEN 5 AND 20 PERCENT WILL LIKELY CONTINUE ACROSS THE
INTERIOR THROUGH THE MIDDLE OF NEXT WEEK, WITH THE DRIEST CONDITIONS
LIKELY REMAINING IN THE INTERIOR MOUNTAINS AND ANTELOPE VALLEY TODAY
AND FRIDAY THERE IS ALSO A 5-10 PERCENT CHANCE OF MONSOONAL SHOWERS
AND THUNDERSTORMS OVER THE MOUNTAINS AND DESERTS NEXT TUESDAY
THROUGH THURSDAY. SOUTHWEST TO NORTHWEST WINDS OF 15 TO 25 MPH WITH
GUSTS TO 35 MPH (EXCEPT ISOLATED GUSTS TO 40 MPH WESTERN ANTELOPE
VALLEY FOOTHILLS) WILL CONTINUE THIS AFTERNOON AND EVENING OVER THE
TYPICAL WIND PRONE INTERIOR AREAS, THEN INCREASING ONSHORE FLOW
WILL BRING STRONGER WIND GUSTS OF 30 TO 45 MPH FROM FRIDAY THROUGH
MONDAY. THE STRONGEST ONSHORE WINDS WILL LIKELY BE FOCUSED ACROSS
THE INTERIOR, ESPECIALLY ANTELOPE VALLEY AND ADJACENT FOOTHILLS,
ALONG WITH THE HIGHWAY 14 CORRIDOR, AND SAN LUIS OBISPO INTERIOR
VALLEYS (ESPECIALLY FRIDAY THROUGH MONDAY).
IN ADDITION, THERE WILL LIKELY BE GUSTY, WARM, AND DRY SUNDOWNER
WINDS CAUSING ELEVATED FIRE WEATHER CONDITIONS IN SOUTHWEST SANTA
BARBARA COUNTY THIS AFTERNOON AND EVENING, MAINLY FROM GAVIOTA TO
SAN MARCOS PASS. THESE AREAS COULD SEE WIND GUSTS OF 30 TO 45 MPH
WITH ISOLATED GUSTS TO AROUND 50 MPH NEAR GAVIOTA. HUMIDITIES ARE
EXPECTED TO LOWER TO BETWEEN 20 AND 40 PERCENT WITH THE GUSTY
SUNDOWNER WINDS, RESULTING IN ONE MORE DAY OF ELEVATED FIRE WEATHER
CONDITIONS ACROSS SOUTHWEST SANTA BARBARA COUNTY.
WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ARE
EXPECTED THROUGH THE MIDDLE OF NEXT WEEK ACROSS THE INTERIOR DUE TO
THE COMBINATION OF GUSTY ONSHORE WINDS WITH VERY WARM AND DRY
CONDITIONS. WHILE THE CHANCE OF REACHING CRITICAL FIRE WEATHER
CONDITION DURATIONS REMAINS LOW THROUGH EARLY NEXT WEEK, BRIEF
