#####################################################################
..DISCUSSION FROM RNOFWFVEF
WARM AND DRY CONDITIONS CONTINUE THROUGH FRIDAY WITH BREEZY
AFTERNOONS. SOUTHWEST WINDS INCREASE OVER THE WEEKEND AS OUR NEXT
SYSTEM MOVES IN, BRINGING WIDESPREAD GUSTS OF 25-45 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
HIGH PRESSURE ALOFT WILL BRING WARMING THROUGH THURSDAY WITH HIGH
TEMPERATURES FOR INLAND AREAS 5 TO 10 DEGREES ABOVE AVERAGE ON
THURSDAY. THE MARINE LAYER WILL DECREASE IN DEPTH TO AROUND
2000 FEET FOR THURSDAY AND FRIDAY. THROUGH THURSDAY, THE LOWEST
DAYTIME HUMIDITY FOR THE DESERTS WILL FALL TO 10 TO 15 PERCENT, BUT
WITH GENERALLY WEAK WINDS. A STRONGER ONSHORE PRESSURE GRADIENT WILL
LIKELY BRING ELEVATED WIND GUSTS (30-40 MPH) FOR THE MOUNTAIN AND
DESERT REGIONS ON FRIDAY AND SATURDAY AFTERNOONS. A LOW PRESSURE
SYSTEM MOVING INTO THE WESTERN STATES WILL BRING COOLING FOR THE
WEEKEND WITH THE MARINE LAYER DEEPENING TO AROUND 3500 FEET ON
EARLY SUNDAY. THIS WILL BE FOLLOWED BY A VERY GRADUAL WARMING TREND
FOR EARLY NEXT WEEK WITH THE MARINE LAYER DECREASING IN DEPTH.
..DISCUSSION FROM PHXFWFPSR
THE THREAT FOR A ISOLATED DRY THUNDERSTORMS OVER SOUTHERN GILA
COUNTY TODAY AND THURSDAY IS THE MAIN FIRE WEATHER HAZARD OVER THE
NEXT FEW DAYS. WINDS WILL FOLLOW TYPICAL DIURNAL TENDENCIES WITH
TYPICAL AFTERNOON UPSLOPE BREEZINESS THE NEXT COUPLE OF AFTERNOONS.
GUSTS BEGIN TO 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%, 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.
