..DISCUSSION FROM RNOFWFVEF
MINIMUM RELATIVE HUMIDITY VALUES WILL CONTINUE TO BOTTOM OUT IN THE
MID-TEENSTO UPPER 30S ACROSS THE REGION AS MONSOONAL MOISTURE
LINGERS ACROSS THE SOUTHWESTERN US. OUTSIDE OF ANY CONVECTIVE
INFLUENCE, WINDS WILL GENERALLY REMAIN LIGHT AND WILL TEND TO FAVOR
TYPICAL DIURNAL DIRECTIONAL TRENDS. HOWEVER, ISOLATED-TO-SCATTERED
SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE EACH AFTERNOON AND
EVENING ACROSS THE SOUTHERN AND EASTERN PORTIONS OF OUR FORECAST
AREA. GUSTY OUTFLOW WINDS, LIGHTNING, AND HEAVY RAINS CAPABLE OF
RESULTING IN FLASH FLOODING WILL BE POSSIBLE WITH ANY STORMS THAT
DEVELOP.
..DISCUSSION FROM LAXFWFSGX
MONSOONAL MOISTURE INCREASES SLIGHTLY TODAY, THEN SLOWLY DECREASE
THIS WEEKEND INTO EARLY NEXT WEEK. THERE IS A 20-40% CHANCE OF
SHOWERS AND THUNDERSTORMS THIS AFTERNOON FOR THE MOUNTAINS AND HIGH
DESERT. CHANCES LOWER TO AROUND 15-20% ACROSS THE SAN BERNARDINO
MOUNTAINS AND LESS THAN 15% ELSEWHERE SATURDAY THROUGH EARLY NEXT
WEEK. GUSTY OUTFLOW WINDS AND ISOLATED DRY LIGHTNING STRIKES ARE
POSSIBLE WITH ANY STORMS THAT DEVELOP. MOISTURE AND PRECIPITATION
CHANCES INCREASE AGAIN TOWARDS THE MIDDLE OF NEXT WEEK. HIGH
TEMPERATURES WILL BE NEAR NORMAL THROUGH NEXT WEEK WITH MODERATE
DAYTIME HUMIDITY AND TYPICAL SEA BREEZES EACH AFTERNOON.
..DISCUSSION FROM PHXFWFPSR
SHOWERS AND THUNDERSTORMS WILL REMAIN POSSIBLE OVER THE ARIZONA
DISTRICTS INTO THIS AFTERNOON WITH MUCH LOWER CHANCES INTO WESTERN
DISTRICTS. ACTIVITY OVER SOUTH-CENTRAL ARIZONA WILL STILL BE CAPABLE
OF PRODUCING LOCALIZED FLOODING THROUGH EARLY AFTERNOON BEFORE
DRYING BEGINS TO MOVE IN FROM THE SOUTH. ELEVATED SOUTHERLY WINDS
ARE ANTICIPATED MUCH OF THE PERIOD FOR THE WESTERN DISTRICTS WITH
LIGHT WINDS ELSEWHERE. ELEVATED HUMIDITIES TODAY WILL KEEP MINIMUM
AFTERNOON HUMIDITY LEVELS FROM 30% IN WESTERN DISTRICTS TO 40-50%
OVER THE EASTERN DISTRICTS. A GRADUAL DRYING TREND OVER THE WEEKEND
WILL DROP MINRHS TO 20-35%.
