AZZ020>028-CAZ030>033-122245- SOUTHWEST ARIZONA/SOUTHEAST CALIFORNIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PHOENIX AZ 1010 AM MST SUN AUG 12 2001 .SYNOPSIS... A LOW PRESSURE SYSTEM OVER ARIZONA MEANS A CHANCE OF SHOWERS AND THUNDERSTORMS FOR SOUTHEAST CALIFORNIA AND ARIZONA TODAY THROUGH MONDAY. HIGH PRESSURE ALOFT WILL BE OFF THE SOUTHERN CALIFORNIA COAST BY MID WEEK. THIS WILL PUSH SOMEWHAT DRIER AIR FROM THE PACIFIC OVER SOUTHEAST CALIFORNIA AND FAR SOUTHWEST ARIZONA...AND ELIMINATE THE CHANCE OF THUNDERSTORMS THERE BY MID WEEK. .DISCUSSION... THE LOW LEVELS OF THE AIRMASS WERE A FEW DEGREES COOLER THIS MORNING COMPARED WITH YESTERDAY MORNING...AND LATE MORNING SURFACE REPORTS WERE ALSO AT LEAST A FEW DEGREES COOLER. THIS SUPPORTS LOWER TEMPERATURES THAT ARE ALREADY IN THE FORECAST FOR TODAY COMPARED WITH YESTERDAY. CYCLONIC FLOW OR A LOW PRESSURE SYSTEM OF SOME SORT IS EXPECTED TO CONTINUE OVER ARIZONA THROUGH TUESDAY. A FLOW ALOFT FROM THE NORTHEAST HAS PUSHED ENOUGH MOISTURE INTO FAR SOUTHEAST ARIZONA TO RESULT IN THUNDERSTORMS THERE...AS WELL AS THE LOWER COLORADO RIVER VALLEY THIS MORNING. PLAN ON KEEPING AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS IN SOUTHEAST CALIFORNIA THROUGH MONDAY NIGHT...AND THE LOWER COLORADO RIVER VALLEY THROUGH TUESDAY. ALSO PLAN ON KEEPING A CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE REMAINDER OF SOUTHWEST AS WELL AS SOUTH-CENTRAL ARIZONA THROUGH TUESDAY NIGHT. AFTER THAT...IT LOOKS AS IF HIGH PRESSURE ALOFT WILL BE NEAR THE SOUTHERN CALIFORNIA COAST WITH DRIER AIR FROM THE PACIFIC MOVING OVER SOUTHEAST CALIFORNIA TO AT LEAST SOUTHWEST ARIZONA WEDNESDAY AND THURSDAY. THERE IS EVEN A POSSIBILITY THAT ENOUGH DRIER AIR COULD PUSH ALL THE WAY TO SOUTH-CENTRAL ARIZONA AND TEMPORARILY ELIMINATE THE CHANCE OF SHOWERS AND THUNDERSTORMS FOR SOUTH-CENTRAL ARIZONA WEDNESDAY AND THURSDAY. WILL DISCUSS THIS ISSUE AT THE MID DAY COORDINATION CALL WITH LAS VEGAS...FLAGSTAFF... AND TUCSON NATIONAL WEATHER SERVICE OFFICES. ELLIS
