|SYNOPSIS FROM THE PHOENIX OFFICE
A large Pacific low pressure system will move across the desert Southwest over the next few days. This system will bring a chance for showers plus potential for thunderstorms along with much cooler conditions. Best chances for rain will be today into early Saturday.

SYNOPSIS FROM THE SAN DIEGO OFFICE
A slow moving low pressure system will bring periods of showers and isolated thunderstorms through early evening decreasing during the weekend. Warmer and dry for next week. The marine layer and weak onshore flow will keep coastal areas cooler with areas of night and morning low clouds and fog. The onshore flow will also bring GUSTY WEST WINDS to the mountains and deserts each late afternoon through late evening.
A slow moving closed low pressure system centered over Southern California will move into the Central Rockies through Sunday. Early this morning a shortwave off the Northern Baja Coast was enhancing showers over the Coastal waters and adjacent Coastal areas of Northern Baja and far Southern California mainly Central and Southern portions of Coastal San Diego County.
For this afternoon and early evening the higher resolution models shift the greater shower and isolated thunderstorm coverage to the mountains, deserts and inland valleys with greatest coverage and rainfall amounts over the mountains. A flash flood watch has been issued for the mountains and deserts for this afternoon and early evening.
The chance of showers and slight chance of thunderstorms will continue for Saturday afternoon and early evening mainly in the mountains, deserts and Inland Valleys with a slight chance of showers for the mountains Sunday afternoon and early evening.
