SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


HOT WEATHER WILL CONTINUE THROUGH TUESDAY UNDER HIGH PRESSURE ALOFT
AND WEAK FLOW. SOME MOISTURE AND INSTABILITY WILL RESULT IN ISOLATED
AFTERNOON AND EARLY EVENING THUNDERSTORMS THROUGH TUESDAY...MAINLY
ALONG AND WEST OF THE MOUNTAINS. DEEPER SUBTROPICAL MOISTURE WILL
ARRIVE ON WEDNESDAY WITH MUCH HIGHER HUMIDITY AND MORE WIDESPREAD
SHOWERS AND THUNDERSTORMS. GRADUAL DRYING IS EXPECTED THURSDAY AND
FRIDAY...BUT SCATTERED SHOWERS AND THUNDERSTORMS WILL STILL BE
POSSIBLE.


Discussion from LAXFWFLOX

WEAK OFFSHORE FLOW EACH MORNING WILL GIVE WAY TO WEAK
ONSHORE FLOW EACH AFTERNOON THROUGH TUESDAY. THIS COMBINED WITH AN
UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BRING A PROLONGED HEAT WAVE
TO INTERIOR SECTIONS THROUGH TUESDAY. MANY VALLEY...LOWER MOUNTAIN
AND DESERT LOCATIONS WILL SEE TEMPERATURES RANGING BETWEEN 100 AND
110 DEGREES DURING THIS PERIOD. MINIMUM HUMIDITIES WILL GENERALLY
RANGE FROM 12 TO 20 PERCENT MONDAY, THEN SLIGHTLY HIGHER TUESDAY. AN
INFLUX OF MID LEVEL MOISTURE AND INSTABILITY WILL LIKELY GENERATE
INCREASED AFTERNOON CLOUD BUILDUPS OVER THE LOCAL MOUNTAINS THROUGH
TUESDAY BUT NO THUNDERSTORMS ARE EXPECTED. THE LONG DURATION OF HOT
AND DRY CONDITIONS WILL BRING AN EXTENDED PERIOD OF ELEVATED FIRE
DANGER ACROSS SOUTHERN CALIFORNIA THROUGH TUESDAY...ESPECIALLY
CONSIDERING THE VERY DRY FUELS. MOUNTAIN AREAS WILL BE ESPECIALLY
VULNERABLE TO LARGE PLUME DOMINATED FIRES OVER THE NEXT FEW DAYS DUE
TO THE HEAT...RELATIVELY LIGHT WINDS...AND INCREASING
INSTABILITY...PROMPTING THE RED FLAG WARNINGS. IN ADDITION...THERE
WILL BE SOME WEAK SUNDOWNER WINDS THE NEXT FEW NIGHTS...WITH
ISOLATED GUSTS IN THE 20 TO 30 MPH RANGE THAT WILL ADD TO THE FIRE
DANGER IN THE SANTA BARBARA COUNTY MOUNTAINS AND ADJACENT FOOTHILLS.

HURRICANE ODILE IS EXPECTED TO CONTINUE TRACKING NORTHWESTWARD OFF
THE COAST BAJA THE NEXT FEW DAYS. REMNANT MOISTURE WILL LIKELY MOVE
INTO SOUTHERN CALIFORNIA WEDNESDAY THROUGH FRIDAY...LEADING TO A
COOLING TREND AND HIGHER HUMIDITIES. THERE IS A SLIGHT CHANCE OF
THUNDERSTORMS FOR THE MOUNTAINS OF LOS ANGELES AND VENTURA
COUNTIES...AS WELL AS THE ANTELOPE VALLEY...WITH A BETTER THREAT OF
STORMS TO THE SOUTH AND EAST OF OUR AREA.



Discussion from SFOFWFHNX

HIGH PRESSURE WILL BRING MAINLY CLEAR SKIES...TERRAIN
DRIVEN WINDS AND WELL ABOVE NORMAL TEMPERATURES TO THE DISTRICT
THROUGH TUESDAY. ONLY SMALL DAY TO DAY CHANGES IN HUMIDITIES CAN
BE EXPECTED THROUGH THE PERIOD. A TROUGH OF LOW PRESSURE
WILL APPROACH THE PACIFIC NORTHWEST AND NORTHERN CALIFORNIA TUESDAY
AND WEDNESDAY. THIS WILL BRING A SLIGHT CHANCE OF THUNDERSTORMS TO THE
MOUNTAINS AND DESERT AREAS BY THURSDAY AS WELL AS INCREASED WINDS
OVER THE SIERRA...ESPECIALLY NEAR YOSEMITE.


Discussion from RNOFWFVEF

HOT AND DRY THROUGH MONDAY WITH A SLIGHT CHANCE FOR
THUNDERSTORMS MAINLY ALONG HIGH TERRAIN IN MOHAVE COUNTY AND
SOUTHERN SAN BERNARDINO COUNTIES. THUNDERSTORM CHANCES INCREASE BY
MID WEEK AS A MOISTURE SURGE APPROACHES THE AREA UNDER THE INFLUENCE
OF HURRICANE ODILE.



Discussion from PHXFWFPSR


INCREASING SOUTHERLY FLOW ALOFT IS EXPECTED TO GRADUALLY INCREASE
AVAILABLE MOISTURE OVER THE REGION OVER THE NEXT SEVERAL
DAYS...LEADING TO INCREASING CHANCES FOR SHOWERS AND
THUNDERSTORMS...WITH THE BEST CHANCES FOR WETTING RAINS TO BE
OVER SOUTH-CENTRAL AZ. ALONG WITH THE INCREASING CHANCES FOR
RAINFALL...AFTERNOON HUMIDITY LEVELS WILL ALSO BE
RISING...WITH GOOD TO EXCELLENT OVERNIGHT RECOVERIES.

...THUNDERSTORMS IMPLY GUSTY WINDS...

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