SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


THE HOT...HUMID AND UNSTABLE ATMOSPHERE WILL BRING A CHANCE OF
THUNDERSTORMS TO THE MOUNTAINS...DESERTS AND PORTIONS OF THE
VALLEYS THROUGH THIS AFTERNOON. A LOW PRESSURE SYSTEM WILL MOVE
INTO THE REGION THURSDAY THROUGH THE WEEKEND WHICH WILL BRING A
DRYING AND COOLING TREND AND A RETURN OF THE MARINE LAYER.
STRONGER ONSHORE FLOW WILL BRING GUSTY WEST WINDS IN THE
MOUNTAINS AND DESERTS THURSDAY EVENING THROUGH FRIDAY MORNING.
HIGHER PRESSURE ALOFT EARLY NEXT WEEK WILL BRING WARMER WEATHER.


Discussion from LAXFWFLOX

A HOT AIR MASS IN PLACE WILL CAUSE TEMPERATURES TO SPIKE UPWARD
SHARPLY THIS MORNING...BUT SOME ONSHORE FLOW THIS AFTERNOON IS EXPECTED
TO BRING 3 TO 5 DEGREES OF COOLING FROM YESTERDAY`S VERY HOT READINGS.
SOME RESIDUAL MOISTURE AND INSTABILITY WILL BRING A CHANCE OF THUNDERSTORMS
TO THE SAN GABRIEL MOUNTAINS AND ANTELOPE VALLEY...MAINLY EASTERN PORTIONS.
IF STORMS DEVELOP...THEY WILL LIKELY BE WETTER THAN YESTERDAY...THEREBY
REDUCING THE THREAT OF DRY LIGHTNING STRIKES. ALSO...IF STORMS DEVELOP...THEY
WILL LIKELY BE SLOW MOVING...RESULTING IN THE POTENTIAL FOR SOME LOCALIZED
FLASH FLOODING.

GUSTY SUNDOWNER WINDS ARE EXPECTED TO RETURN TO THE SANTA BARBARA SOUTH
COAST AND SANTA YNEZ RANGE LATER THIS AFTERNOON AND EVENING. THE STRONGEST
WINDS WILL ONCE AGAIN BE FOCUSED ACROSS WESTERN PORTIONS...WHERE GUSTS
UP TO 40 MPH CAN BE EXPECTED. TEMPERATURES ARE NOT EXPECTED TO
BE QUITE AS HOT AND DRY AS YESTERDAY...BUT WE COULD STILL SEE TEMPERATURES
CLIMB INTO THE LOWER TO MID 90S WITH HUMIDITIES FALLING TO BETWEEN 15
AND 25 PERCENT.

MORE SIGNIFICANT COOLING IS EXPECTED THURSDAY INTO FRIDAY AS STRONGER ONSHORE
FLOW AND MARINE LAYER CLOUDS RETURN TO THE REGION. MILD TEMPERATURES EXPECTED
THIS WEEKEND...THEN A GRADUAL WARMING TREND EARLY NEXT WEEK. THERE IS THE
POTENTIAL FOR MORE SIGNIFICANT HEAT WITH OFFSHORE FLOW BY THE MIDDLE OF
NEXT WEEK.




Discussion from SFOFWFHNX

AN UPPER TROUGH WILL MOVE INTO CALIFORNIA TONIGHT
AND THURSDAY AND WILL REMAIN OVER CENTRAL CALIFORNIA THROUGH THE
WEEKEND. TEMPERATURES WILL COOL BACK TO NEAR OR SLIGHTLY BELOW
NORMAL LEVELS THURSDAY AND FRIDAY WITH A SLIGHT CHANCE OF SHOWERS
AND THUNDERSTORMS OVER THE SIERRA NEVADA THURSDAY THROUGH SUNDAY.
HIGH PRESSURE WILL REBUILD EARLY NEXT WEEK FOR A WARMING AND
DRYING TREND.



Discussion from RNOFWFVEF

THE REMNANTS OF HURRICANE ODILE WILL TRACK EAST OF OUR
AREA THROUGH THURSDAY. A SURGE OF MOISTURE FROM THIS STORM WILL
INCREASE THE THREAT OF SCATTERED AFTERNOON THUNDERSTORMS AND FLASH
FLOODING FOR PORTIONS OF THE AREA. AN UPPER LEVEL DISTURBANCE WILL
MOVE INTO THE AREA ON THURSDAY EVENING TO BEGIN A DRYING TREND.
THUNDERSTORM CHANCES LOOK TO BE LIMITED TO EASTERN PORTIONS OF
LINCOLN AND MOHAVE COUNTY FRIDAY.



Discussion from PHXFWFPSR


TROPICAL MOISTURE FROM FORMER HURRICANE ODIEL WILL CONTINUE TO COVER
THE REGION THROUGH FRIDAY. A CHANCE OF SHOWERS AND THUNDERSTORMS WILL
CONTINUE MAINLY IN SOUTH CENTRAL ARIZONA...BUT PARTICULARLY IN THE
MOUNTAINS OF SOUTHERN GILA COUNTY. MINIMUM RELATIVE HUMIDITIES WILL
REMAIN HIGHER THAN NORMAL...IN THE 30 TO 40 PERCENT RANGE. THE
EXCEPTION IS SOUTHEAST CA WHERE MINIMUM HUMIDITIES WILL HOVER NEAR 20
PERCENT. AFTERNOON SOUTHWEST WINDS WILL BE LIGHTER THAN NORMAL...
UNDER 15 MPH. OVERNIGHT RECOVERY WILL BE FAIR.


...THUNDERSTORMS IMPLY GUSTY WINDS...

NOTE...ADDITIONAL FIRE WEATHER FORECAST INFORMATION CAN BE FOUND
IN THE AREA FORECAST DISCUSSION. SEE PRODUCT PHXAFDPSR.
