SUMMARY OF FWF DISCUSSIONS

Discussion from LAXFWFSGX


UPPER LEVEL TROUGH ALONG THE WEST COAST WILL BRING DRIER AND MORE
STABLE AIR TO THE REGION TODAY.  HIGH PRESSURE WILL THEN BUILD BACK
ACROSS THE REGION ON FOR FRIDAY AND THE WEEKEND...WITH DRIER AND
WARMER CONDITIONS DEVELOPING FOR FRIDAY AND SATURDAY.
HOWEVER...SOME MOISTURE AND INSTABILITY WILL START TO SPREAD BACK
ACROSS THE REGION ON SUNDAY...WITH A SLIGHT CHANCE OF AFTERNOON
SHOWERS AND THUNDERSTORMS POSSIBLE OVER THE MOUNTAINS AND DESERTS
AND A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS WITH WETTING RAINS
FOR MONDAY THROUGH WEDNESDAY.

***THUNDERSTORMS IMPLY GUSTY AND ERRATIC WINDS***


Discussion from LAXFWFLOX


INCREASING ONSHORE FLOW AND A DEEPER MARINE LAYER WILL CONTINUE TO
BRING A SLIGHT COOLING TREND TO MOST AREAS TODAY...WITH LITTLE CHANGE
INTO FRIDAY. THE MOUNTAINS...DESERTS...AND FAR INTERIOR VALLEYS WILL
CONTINUE TO BE DRY...WITH MANY LOCATIONS REPORTING HUMIDITIES IN THE TEENS.
THESE SAME AREAS WILL ALSO CONTINUE TO SEE ONSHORE WINDS GUSTING TO
BETWEEN 25 AND 35 MPH EACH AFTERNOON THROUGH FRIDAY...WITH
ISOLATED GUSTS AS HIGH AS 45 MPH IN THE FOOTHILLS OF THE ANTELOPE
VALLEY. THE COMBINATION OF GUSTY ONSHORE WINDS AND LOW HUMIDITIES
WILL BRING ELEVATED FIRE DANGER EACH AFTERNOON OVER INTERIOR AREAS
THROUGH FRIDAY. AS HIGH PRESSURE OVER THE DESERT SOUTHWEST BEGINS TO
BUILD WESTWARD TOWARDS SOUTHERN CALIFORNIA...A WARMING TREND IS
EXPECTED ACROSS THE FORECAST AREA OVER THE WEEKEND. FROM SUNDAY THROUGH
WEDNESDAY...A SURGE OF MONSOONAL MOISTURE IS EXPECTED TO MOVE INTO THE
MOUNTAINS AND DESERTS OF SOUTHERN CALIFORNIA. THE TIMING AND AREAL
EXTENT OF THIS MOISTURE SURGE IS STILL IN QUESTION...BUT THE GREATEST
THREAT OF THUNDERSTORMS AT THIS TIME APPEARS TO BE MONDAY INTO TUESDAY.



Discussion from SFOFWFHNX

THE DISTRICT WILL REMAIN ON THE WESTERN PERIPHERY OF
AN AREA OF MONSOONAL MOISTURE THROUGH FRIDAY WITH ISOLATED AFTERNOON
AND EARLY EVENING THUNDERSTORMS ALONG THE SIERRA CREST NORTH OF KINGS
CANYON. A DRIER AND MORE STABLE AIR MASS WILL MOVE INTO THE REGION
BY FRIDAY NIGHT AND REMAIN OVER THE DISTRICT THROUGH THE WEEKEND.
ANOTHER INFLUX OF MONSOONAL MOISTURE IS LIKELY EARLY NEXT WEEK WITH
A RENEWED THREAT OF THUNDERSTORMS OVER THE MOUNTAINS AND DESERT. AN
ONSHORE FLOW WILL SUPPORT GUSTY WINDS IN THE KERN COUNTY MOUNTAINS
AND DESERT AND THE WEST SIDE OF THE SAN JOAQUIN VALLEY DURING THE
NEXT COUPLE OF EVENINGS. TEMPERATURES WILL TREND A BIT LOWER THROUGH
FRIDAY THEN WARM TO WELL ABOVE NORMAL BY SUNDAY.



Discussion from RNOFWFVEF

ABUNDANT MOISTURE WILL COMBINE WITH AN UPPER LEVEL
DISTURBANCE TO GENERATE ISOLATED TO SCATTERED THUNDERSTORMS TODAY
ACROSS MUCH OF THE AREA. DRIER AIR WILL PUSH IN BEHIND THE
DISTURBANCE...LIMITING ANY THUNDERSTORM CHANCES TO PORTIONS OF
MOHAVE COUNTY ARIZONA FOR THE FRIDAY THROUGH SUNDAY TIME FRAME.
TEMPERATURES WILL WARM TO ABOVE NORMAL LEVELS OVER THE WEEKEND DUE
TO THE DRIER AIR.



Discussion from PHXFWFPSR




A SLIGHT DRYING TREND WILL CONTINUE THIS AFTERNOON ACROSS SOUTHEAST
CALIFORNIA WITH HIGH HUMIDITIES REMAINING IN PLACE ACROSS ARIZONA.
THE DRYING WILL PUSH EASTWARD THROUGH MOST OF ARIZONA ON FRIDAY WITH
MINIMUM HUMIDITIES DROPPING INTO THE TEENS ACROSS THE ENTIRE REGION
FOR FRIDAY AFTERNOON. THERE REMAINS A SLIGHT CHANCE OF THUNDERSTORMS
ACROSS THE SOUTH-CENTRAL ARIZONA DESERTS TODAY...WITH BETTER CHANCES
ACROSS THE HIGHER TERRAIN AREAS. THUNDERSTORMS CHANCES FOR FRIDAY
WILL BE CONFINED TO HIGHER TERRAIN AREAS ONLY.

...THUNDERSTORMS IMPLY GUSTY WINDS...

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