DISCUSSION
THE THREAT FOR AN ISOLATED DRY THUNDERSTORM OVER SOUTHERN GILA
COUNTY THIS AFTERNOON IS THE MAIN FIRE WEATHER HAZARD IN THE SHORT
TERM. WINDS THROUGH THIS AFTERNOON WILL FOLLOW TYPICAL DIURNAL
TENDENCIES WITH TYPICAL AFTERNOON UPSLOPE BREEZINESS. GUSTS PICK
UP FRIDAY AND INTO THE WEEKEND, MAINLY ACROSS THE LOWER COLORADO
RIVER VALLEY AND HIGH TERRAIN AREAS OF THE EASTERN DISTRICTS WITH
READINGS REACH UPWARDS OF 25-30 MPH, AND LOCALLY UP TO 35 MPH ON
SATURDAY. 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 CAN BE EXPECTED WITH
LOCALIZED HIGHER GUSTS. OVERNIGHT RECOVERY WILL OFFER VERY LITTLE
IN TERMS OF RELIEF AS MAXRHS RUN ONLY BETWEEN 15-45% FOR MOST
LOCATIONS.
