HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE TUCSON AZ 1112 PM MST MON AUG 15 2005 AZZ019-029>035-161400- NORTHERN GREENLEE COUNTY-UPPER GILA RIVER VALLEY-COCHISE COUNTY- SOUTHEAST PINAL COUNTY-TUCSON METRO/MARANA/GREEN VALLEY-SANTA CRUZ COUNTY-TOHONO OODHAM NATION-WESTERN PIMA COUNTY- 1112 PM MST MON AUG 15 2005 THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ARIZONA .DAY ONE...TODAY AND TONIGHT SYNOPSIS...ALTHOUGH DRIER AIR HAS STARTED TO MOVE ACROSS THE AREA FROM THE SOUTHWEST...THERE WILL BE ENOUGH LINGERING MOISTURE AROUND TODAY AND THIS EVENING TO SUPPORT ANOTHER ROUND OF THUNDERSTORMS... ESPECIALLY FOR AREAS NORTH AND EAST OF TUCSON AND IN THE MOUNTAINS. THE DRIER AIR WILL CONTINUE TO SPREAD ACROSS THE AREA THROUGH MIDWEEK AS A LOW PRESSURE MOVES FROM SOUTHERN CALIFORNIA INTO THE GREAT BASIN REGION. DISCUSSION...A LOW PRESSURE SYSTEM OVER SOUTHERN CALIFORNIA WILL MOVE NORTHEAST INTO NEVADA BY TUESDAY. THIS FEATURE WILL PROVIDE SOME UPPER LEVEL SUPPORT FOR THUNDERSTORMS TODAY. THE AIRMASS WAS A LITTLE BIT DRIER AND WARMER ALOFT IN THE WAKE OF THE DISTURBANCE THAT MOVED THROUGH SOUTHEAST ARIZONA SUNDAY MORNING. THIS DRIER AIR AND POCKET OF WARM AIR AT FIFTEEN THOUSAND FEET WILL MAKE IT DIFFICULT FOR THUNDERSTORMS TO DEVELOP IN THE DESERT VALLEYS TODAY. HOWEVER...THE STEERING FLOW WAS MUCH STRONGER COMPARED TO THE PAST FEW DAYS DUE TO THE VICINITY OF THE UPPER LOW OVER CALIFORNIA. THIS STRONGER FLOW WILL BE FAVORABLE ENOUGH TO STEER THUNDERSTORMS OFF THE MOUNTAINS AND INTO THE LOWER VALLEYS LATER THIS AFTERNOON AND EVENING. THE MAIN THREAT FROM THUNDERSTORMS TODAY WILL BE HEAVY DOWNPOURS AND STRONG OUTFLOW WINDS. DUE TO THE POCKETS OF 1 TO 3 INCHES OF RAIN FROM STORMS YESTERDAY...ADDITIONAL RAINFALL MAY CAUSE RUNOFF PROBLEMS AGAIN TODAY. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY THERE WILL BE A GRADUAL DECREASE IN THUNDERSTORMS THIS COMING WEEK AS A DRIER WESTERLY ALOFT PERSISTS OVER THE REGION. THIS DRIER AIRMASS WILL ALSO LEAD TO WARMER AFTERNOON HIGH TEMPERATURES BY THE MIDDLE OF THE WORK WEEK. .SPOTTER INFORMATION STATEMENT...
