..DISCUSSION FROM RNOFWFVEF
ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS WILL CONTINUE THROUGH
FRIDAY WITH BREEZY AFTERNOON WINDS. SOUTHWEST WINDS INCREASE OVER
THE WEEKEND AS OUR NEXT SYSTEM MOVES IN, BRINGING WIDESPREAD GUSTS
OF 30-45 MPH. RH VALUES ARE FORECAST TO BE 5-15% EACH AFTERNOON,
WITH OVERNIGHT RECOVERY ONLY 15-35% IN MOST LOCATIONS. ELEVATED TO
NEAR-CRITICAL FIRE WEATHER CONDITIONS LIKELY WHERE FUELS ARE
RECEPTIVE.
..DISCUSSION FROM LAXFWFSGX
WARMING WILL CONTINUE FOR TODAY WITH HIGH TEMPERATURES 5 TO
10 DEGREES ABOVE AVERAGE. THIS WILL BE FOLLOWED BY COOLING THROUGH
THE WEEKEND WITH SUNDAY HIGH TEMPERATURES A FEW TO AROUND 5 DEGREES
BELOW AVERAGE. A MARINE LAYER AROUND 2000 FEET DEEP WILL DEEPEN TO
AROUND 3000 TO 3500 FEET FOR THE WEEKEND, THEN SLOWLY DECREASE IN
DEPTH EARLY NEXT WEEK TO AROUND 2000 FEET FOR NEXT WEDNESDAY. LOWEST
DAYTIME HUMIDITY FOR THE DESERTS WILL FALL TO AROUND 10 PERCENT FOR
TODAY AND FRIDAY, THEN RECOVER TO AROUND 15 TO 25 PERCENT FOR THE
WEEKEND. SOUTHWEST TO WEST WINDS DURING THE AFTERNOON AND EVENING
ON FRIDAY AND SATURDAY FOR THE MOUNTAINS AND DESERTS WILL GUST TO
30 TO 40 MPH. THERE WILL BE SLOW WARMING FOR EARLY NEXT WEEK WITH
HIGH TEMPERATURES ON WEDNESDAY WITHIN A FEW DEGREES OF AVERAGE.
..DISCUSSION FROM PHXFWFPSR
THE THREAT FOR A ISOLATED DRY THUNDERSTORMS OVER SOUTHERN GILA
COUNTY THIS AFTERNOON IS THE MAIN FIRE WEATHER HAZARD DURING THE
FORECAST PERIOD. WINDS WILL FOLLOW FAMILIAR LIGHT AND DIURNAL
TENDENCIES WITH TYPICAL AFTERNOON UPSLOPE BREEZINESS THROUGH THIS
AFTERNOON. GUSTS PICK UP FRIDAY AND INTO THE WEEKEND, MAINLY ACROSS
THE LOWER COLORADO RIVER VALLEY AND HIGH TERRAIN AREAS OF THE
EASTERN DISTRICTS. WITH DAILY MINRHS HOVERING CLOSE TO 5-10% FOR THE
MAJORITY OF THE REGION, EVEN MARGINAL BREEZES WILL RESULT IN PERIODS
OF ELEVATED FIRE WEATHER CONDITIONS. ISOLATED INSTANCES OF NEAR
CRITICAL TO CRITICAL CONDITIONS CANNOT BE RULED OUT. OVERNIGHT
RECOVERY WILL OFFER VERY LITTLE IN TERMS OF RELIEF AS MAXRHS RUN
BETWEEN ONLY 15-45% FOR MOST AREAS.
