A storm passing by to the north will help to deepen the marine layer tonight into tomorrow morning with a brief cool down all around the county.

Onshore winds will turn offshore on Thursday, with warmer conditions for St. Patrick's Day. Temperatures will be near 70 at the coast and mid to upper 70s inland under sunny skies. Santa Ana winds out of the northeast at 15 to 40mph Thursday morning for the valleys and mountains. We will enjoy mild weather again on Friday, before we cool back down this weekend.

A storm dives south bringing a chance for showers Saturday night into Sunday. Temperatures will cool to the low to mid-60s for the coast and valleys on Sunday, with 40s in the mountains and 70s in the deserts.

Preliminary forecast totals look to average between a few hundredths to .50" from the coast to the mountains, with lesser totals in the deserts. Snow levels will hover between 5,000 to 5,500' which may bring a dusting of snow to the highest mountains, but only rain is expected in Julian.

Gusty winds will target the mountains and deserts Wednesday with westerly gusts of 15 to 35mph and then again over the weekend with westerly gusts of 30 to 55mph.

Sunshine returns on Monday with a warming trend next week.
