..DISCUSSION FROM RNOFWFVEF
TEMPERATURES CONTINUE TO COOL AND HUMIDITIES CONTINUE TO IMPROVE AS
MORE MONSOONAL MOISTURE BUILDS INTO THE AREA. THIS INCREASE IN
MOISTURE WILL ALSO CALL FOR BETTER CHANCES FOR DAILY STORM CHANCES.
AFTER SOME EARLY LIGHT SHOWERS, SOUTHERN PORTIONS OF THE DISTRICT
WILL SEE STORMS CHANCES BUILD AROUND NOON, WITH STORM CHANCES
BECOMING WIDESPREAD IN THE MID- AFTERNOON. ISOLATED THUNDERSTORMS
WILL FAVOR THE HIGHER TERRAIN BEFORE SPREADING INTO ADJACENT
VALLEYS. STORM CHANCES DECREASE INTO THE EARLY NIGHT, BUT DON'T
FULLY DISSIPATE UNTIL THE LATE NIGHT. NO SIGNIFICANT WIND IS
EXPECTED ASIDE FROM STORM-PRODUCED WINDS. THURSDAY WILL SEE
ADDITIONAL CHANCES FOR AFTERNOON STORMS BUT WITH LESS OF A SPREAD
AND CHANCES END INTO THE LATE EVENING. A PATTERN CHANGE ON FRIDAY
LOOKS TO GREATLY REDUCE THE CHANCES AND SPREAD OF STORMS, BUT STILL
OFFERS SOME CHANCES. THE PATTERN IS EXPECTED TO CALM FOR THE
WEEKEND ITSELF WITH SLIGHTLY REDUCED HUMIDITIES AND SOME BREEZY
WINDS.
..DISCUSSION FROM LAXFWFSGX
THE FLOW ALOFT WILL BECOME GRADUALLY SOUTHWESTERLY WITH DRYING OF
MONSOONAL MOISTURE THE NEXT FEW DAYS. THERE REMAINS A SLIGHT CHANCE
OF SHOWERS AND THUNDERSTORMS FOR THE MOUNTAINS AND DESERTS FROM LATE
THIS MORNING THROUGH THIS AFTERNOON. IN ADDITION TO DRYING ALOFT,
THERE WILL ALSO BE GRADUAL DRYING OF LOWER LEVEL MOISTURE THROUGH
EARLY NEXT WEEK. HIGH TEMPERATURES WILL COOL THROUGH THURSDAY, THEN
SLOWLY WARM INTO THE MIDDLE OF NEXT WEEK. LOWEST DAYTIME HUMIDITY
FOR THE DESERTS WILL FALL TO AROUND 15 PERCENT FOR MONDAY AND
TUESDAY OF NEXT WEEK. BREEZY CONDITIONS ARE EXPECTED EACH AFTERNOON
AND EARLY EVENING INTO NEXT WEEK FROM THE DESERT SLOPES OF THE
MOUNTAINS INTO THE DESERTS AND THROUGH THE MOUNTAIN PASSES WITH THE
STRONGER WINDS FOR TODAY AND THURSDAY.
..DISCUSSION FROM PHXFWFPSR
ELEVATED HUMIDITY LEVELS, COOLER TEMPERATURES, AND GOOD CHANCES FOR
WETTING RAINS ARE ANTICIPATED THROUGH THURSDAY MORNING OVER AT LEAST
THE EASTERN DISTRICTS. THE BEST RAIN CHANCES WILL BE DURING THE
EVENING AND OVERNIGHT HOURS TONIGHT WITH LINGERING CHANCES THROUGH
THURSDAY AFTERNOON. AFTERNOON MINRHS WILL RANGE BETWEEN 25-35%
ACROSS THE LOWER DESERTS AND 40-50% FOR THE EASTERN HIGH TERRAIN,
WHILE OVERNIGHT RECOVERIES WILL REMAIN EXCELLENT. WINDS WILL
PREDOMINATELY BE OUT OF THE SOUTH SOUTHWEST MUCH OF THE PERIOD WITH
THE EXCEPTION OF ANY MODEST OUTFLOWS FROM THUNDERSTORM ACTIVITY.
