|Imperial County Weather Synopsis|
|SYNOPSIS FROM THE SAN DIEGO OFFICE
Fair and hot weather will continue today. An increase in monsoonal moisture this weekend will increase the chance of showers and thunderstorms in the mountains and deserts each afternoon and evening. It will also be slightly cooler this weekend into early next week
Friday will be a transition day as heights begin to fall across all areas. Return monsoonal moisture will begin to encroach on our area as well, bringing a slight chance for afternoon and evening convection. Monsoonal moisture will make a more noteworthy push Sunday and Monday, with a plume of nearly 2" PW airmass riding north along the Baja coast and also across the Sonoran Desert. This airmass should be capable of generating heavy rainfall and possible flooding in the deserts and mountains on Sunday and/or Monday
SYNOPSIS FROM THE PHOENIX OFFICE
Strong high pressure will once again keep thunderstorm activity somewhat isolated today as well as maintaining very hot temperatures. However, this high pressure system will begin to weaken starting Friday, with better moisture profiles streaming north throughout the region. In addition to somewhat cooler temperatures, a marked increase in thunderstorm activity will impact the area through the weekend and into the beginning of next week
