Technically still a WET day from Friday night's system. However today will remain Sunny and mild with light N/NW flow. Dispersion will remain good.
*** WET Permissive Burn Day ***
Active weather expected for the beginning half of this week, as a deep closed low spins over the Pacific and works it's way inland during Mon, Tue and Wed. Periods of light rain and scattered thunderstorms to begin Monday afternoon with the more persistent valley rains expected Tuesday. The second half of the week dries out as a high pressure ridge follows. Dispersion remains favorable throughout the period. Stay Tuned!
