THERE IS A RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EARLY EVENING OVER THE EASTERN MOGOLLON RIM AND WHITE MOUNTAINS. AN ABOVE- AVERAGE RISK OF SEVERE THUNDERSTORMS WILL EXIST OVER THE SOUTH- CENTRAL DESERT...INCLUDING THE GREATER PHOENIX METROPOLITAN AREA...EARLY THIS EVENING UNTIL AROUND MIDNIGHT. STRONG GUSTY WINDS LOCALLY HEAVY RAINFALL...AND FREQUENT INTENSE LIGHTNING WILL BE ASSOCIATED WITH THE STRONGER STORMS. SMALL HAIL IS LIKELY WITH THE STRONGER STORMS...ESPECIALLY THOSE OVER HIGHER TERRAIN. UPPER LEVEL WIND DATA SUGGEST THAT STORMS WHICH FORM OVER THE EASTERN MOGOLLON RIM AND WHITE MOUNTAINS THIS AFTERNOON WILL REDEVELOP TOWARD THE SOUTHWEST...AND GENERATE OUTFLOW WINDS THAT WILL REACH ADJACENT LOWER DESERT LOCATIONS BY EARLY THIS EVENING. THIS OUTFLOW IS EXPECTED TO TRIGGER NEW THUNDERSTORMS OVER PORTIONS OF THE LOWER DESERTS...INCLUDING THE GREATER PHOENIX METROPOLITAN AREA...BY LATE THIS EVENING OR EARLY TONIGHT. AT 120 PM...STRONG THUNDERSTORMS ALREADY EXISTED OVER THE WHITE MOUNTAINS...AND THUNDERSTORMS WERE JUST BEGINNING TO DEVELOP OVER THE MOGOLLON RIM. THE AIRMASS OVER THE SOUTH-CENTRAL DESERT HAS MOISTENED CONSIDERABLY SINCE SATURDAY AFTERNOON. EARLY THIS MORNING...MOISTURE FROM THE GULF OF CALIFORNIA SURGED NORTHWARD OVER SOUTHWEST ARIZONA...AND LOW LEVEL WESTERLY WINDS WILL TRANSPORT THIS MOISTURE OVER THE SOUTH- CENTRAL DESERTS THIS AFTERNOON AND EVENING. DEW POINT TEMPERATURE ...A MEASURE OF ATMOSPHERIC MOISTURE CONTENT...IS IN THE MID 60S...WHICH IS ABOVE THE CLIMATOLOGICAL NORM FOR MID JULY. MUCH OF CENTRAL AND SOUTHERN ARIZONA CONTINUES TO DESTABILIZE AS PARTLY CLOUDY SKIES ALLOW FOR ADDITIONAL SURFACE HEATING...BUT TEMPERATURES THIS AFTERNOON ARE A FEW DEGREES LOWER DUE TO THE INCREASE IN LOW-LEVEL MOISTURE. AT 1 PM...PHOENIX REPORTED PARTLY SKIES AND 97 DEGREES WITH A DEW POINT TEMPERATURE OF 65 DEGREES. ON THE OTHER HAND...TEMPERATURES OVER MUCH OF PIMA COUNTY HAVE BEEN HELD DOWN DUE TO CLOUD COVER AND SCATTERED LIGHT SHOWERS...SO THE ATMOSPHERE IN THAT AREA IS MORE STABLE AND LESS LIKELY TO SUPPORT STRONG THUNDERSTORMS THIS AFTERNOON AND EVENING. AT 1 PM...TUCSON REPORTED CLOUDY SKIES...LIGHT RAIN...AND 79 DEGREES. GREEN
