..DISCUSSION FROM RNOFWFVEF
ISOLATED SHOWERS AND THUNDERSTORMS POSSIBLE THIS AFTERNOON ACROSS
THE HIGHER TERRAIN OF NORTHWESTERN ARIZONA AND THE SOUTHERN GREAT
BASIN. GIVEN THE ISOLATED NATURE OF THESE STORMS AND THE DRY
LOW-LEVELS OF THE ATMOSPHERE, WIDESPREAD WETTING RAINS ARE NOT
EXPECTED. EXPECT AN INCREASE IN AFTERNOON COVERAGE OF MONSOON
STORMS THURSDAY - SATURDAY AS MOISTURE SURGES NORTH. HOTTER THAN
NORMAL TEMPERATURES CONTINUE THROUGH THE END OF THE WEEK. AFTERNOON
RELATIVE HUMIDITIES BOTTOM OUT IN THE 10 TO 20 PERCENT RANGE FOR
MUCH OF THE AREA WITH OVERNIGHT RECOVERIES BETWEEN 20 AND 30 PERCENT
IN THE DESERTS AND BETWEEN 25 AND 40 PERCENT IN THE MOUNTAINS.
EXPECT IMPROVING OVERNIGHT RECOVERY RH THIS WEEKEND AS MOISTURE
INCREASES.
..DISCUSSION FROM LAXFWFSGX
THROUGH FRIDAY...LOW HUMIDITY AND LOCALLY GUSTY WESTERLY WINDS
COULD PRODUCE ELEVATED FIRE WEATHER CONDITIONS DURING THE AFTERNOON
HOURS IN AREAS ABOVE 2,000 FT, ESPECIALLY IN AND BELOW MOUNTAIN
PASSES AND CANYONS. PERSISTENT HIGH PRESSURE WILL CONTINUE HOT DAYS
AND NEAR-RECORD WARM NIGHTS THROUGH FRIDAY NIGHT, WITH A SLIGHT
CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE MOUNTAINS THIS
AFTERNOON AND FRIDAY AFTERNOON. HIGH PRESSURE WILL WEAKEN FOR THE
WEEKEND INTO EARLY NEXT WEEK WITH HIGH TEMPERATURES LOWERING TO
AROUND AVERAGE NEXT MONDAY. DRY CONDITIONS WITH STRONGER ONSHORE
FLOW WILL PRODUCE ELEVATED FIRE WEATHER CONDITIONS, MAINLY IN THE
MOUNTAIN PASSES AND CANYONS.
..DISCUSSION FROM PHXFWFPSR
TEMPERATURES WILL TOP OUT AROUND 110-117 DEGREES ACROSS THE LOWER
DESERTS TODAY AND REMAIN LARGELY ABOVE 110 THROUGH THE REST OF THIS
WEEK. MOSTLY DRY CONDITIONS ARE ANTICIPATED THROUGH TOMORROW WITH
ONLY ISOLATED STORM ACTIVITY ANTICIPATED. ANY STORMS THAT DO FORM
WILL BE CAPABLE OF PRODUCING GUSTY OUTFLOW WINDS. POOR TO FAIR
OVERNIGHT RECOVERIES BETWEEN 30-50% WILL BE COMMON TONIGHT AND
THURSDAY NIGHT. AFTERNOON MINIMUM HUMIDITIES WILL DROP TO 10-15%
AREAWIDE TODAY AND IMPROVE SLIGHTLY TO AROUND 15-20% ON THURSDAY.
WINDS WILL OVERALL BE LIGHT AND FOLLOW DIURNAL TENDENCIES, WITH
MODEST AFTERNOON UPSLOPE/UPVALLEY BREEZINESS EACH DAY.
