..DISCUSSION FROM RNOFWFVEF
.ONE MORE ROUND OF ISOLATED AFTERNOON SHOWERS AND THUNDERSTORMS IS
EXPECTED TODAY. THIS ACTIVITY WILL BE CONFINED TO NORTHERN AND
EASTERN MOHAVE COUNTY, WITH ERRATIC, GUSTY WINDS AND LIGHTNING
STRIKES THE MAIN CONCERNS. WIDESPREAD WETTING RAINS ARE NOT
EXPECTED. ELSEWHERE, A DRYING TREND WILL CONTINUE THIS AFTERNOON AS
MINIMUM RH VALUES DROP BELOW 20 PERCENT IN MOST AREAS, AND ONLY
POOR TO FAIR OVERNIGHT RECOVERY IS EXPECTED. FAIRLY WIDESPREAD
CRITICAL TO EXTREME FIRE WEATHER CONDITIONS WILL DEVELOP ON FRIDAY
AND PERSIST THROUGH SATURDAY EVENING AS SOUTHERLY TO SOUTHWESTERLY
WINDS INCREASE SUBSTANTIALLY. 20FT WINDS WILL GUST TO 35 TO 50 MPH
AT TIMES, WITH SUSTAINED SPEEDS AROUND 20 TO 30 MPH. STRONGER 20FT
WINDS AND GUSTS CAN BE EXPECTED IN TYPICAL TERRAIN-FAVORED AREAS.
THESE WINDS, COMBINED WITH MINIMUM RH VALUES AROUND 5 TO 15 PERCENT
AND POOR NOCTURNAL RECOVERY, WILL LEAD TO HIGH FIRE DANGER, WITH
CONCERN FOR THE DEVELOPMENT OF NEW WIND-DRIVEN WILDFIRES IGNITED BY
THUNDERSTORMS THAT MOVED THROUGH THE AREA OVER THE LAST COUPLE OF
DAYS.
..DISCUSSION FROM LAXFWFSGX
BELOW AVERAGE TEMPERATURES, INCREASED ONSHORE WINDS, AND A DEEPER
MARINE LAYER CAN BE EXPECTED THIS WEEKEND. THE INITIAL ONSET OF
WINDS WITH GUSTS 35 TO 50 MPH ON THE DESERT MOUNTAIN SLOPES INTO
THE DESERTS WILL BE ACCOMPANIED WITH MINIMUM AFTERNOON RELATIVE
HUMIDITY OF 7 TO 15 PERCENT IN THE DESERTS. INCREASED WINDS AND DRY
CONDITIONS WILL LEAD TO NEAR CRITICAL TO LOCALLY CRITICAL FIRE
WEATHER CONDITIONS FRIDAY. HUMIDITY WILL IMPROVE TO NEAR 20 PERCENT
BY THE TIME THE WINDS PEAK IN STRENGTH ON SATURDAY AFTERNOON. PEAK
WIND GUSTS OF 50 TO 65 MPH, LOCALLY HIGHER POSSIBLE BELOW THE SAN
GORGONIO PASS, CAN BE EXPECTED. WINDS WILL WEAKEN SUNDAY.
CONDITIONS WILL GRADUALLY WARM NEXT WEEK WITH HIGH TEMPERATURES
RETURNING TO NEAR AVERAGE BY THE END OF NEXT WEEK.
..DISCUSSION FROM PHXFWFPSR
AN UNUSUAL WEATHER PATTERN FOR LATE JUNE WILL SET UP OVER THE
REGION THROUGH SATURDAY RESULTING IN A POTENTIALLY DANGEROUS FIRE
WEATHER SITUATION CAPABLE OF SUPPORTING EXTREME FIRE BEHAVIOR. AS
AFTERNOON HUMIDITY LEVELS FALL BELOW 10%, WIND GUSTS 20-40 MPH WILL
BECOME COMMON WHILE TEMPERATURES HOVER IN A SEASONALLY HOT RANGE.
OVERNIGHT RECOVERY WILL ONLY BE POOR TO FAIR. RED FLAG WARNINGS
CONTINUE WITH CONDITIONS SATURDAY WORSE THAN FRIDAY, AND ABOUT AS
DANGEROUS AS IT GETS FOR THIS TIME OF YEAR.
