Mostly clear weather will continue through the week. Light drizzle is possible along the coast Tuesday followed by warm days and cold night through Thursday.

High pressure has rapidly started to build over the area today, brining clear skies and gradually warming temperatures. Most areas today have warmed into the mid 50s. Light onshore flow may even allow for a weak marine layer to form along the coast, though instability aloft will make any such layer inconsistent at most.

A quick moving upper level shortwave is expected to cross the area Tuesday. Little impacts are expected with some limited southeast gusts to 20 mph in exposed areas. Light drizzle is possible along the coast, but little more than a tenth of an inch is expected anywhere.

Strong high pressure to the east will bring consistent offshore flow late in the week, keeping skies clear and conditions dry. Onshore afternoon breezes could still form some kind of marine layer, but little stratus formation is expected. Clear skies along with increasingly long days could allow for some temperatures as high as 70 Thursday for Mendocino County. At the same time, dry offshore flow will allow for near freezing temperatures each night.

All cluster ensemble members show a deeper low pressure system approaching the coast late in the week into the weekend. Deterministic models are skewing towards the dry side with only 0.2 to 0.4 inches of rain and southerly gusts to 30 mph. About 35% of the members have no precipitation at all. /JHW

High pressure will gradually weaken over the E Pacific. Gusty northerly winds will gradually diminish tonight...while a NW swell will slowly subside through early Tuesday. A weak cold front will approach the area from the NW on Tuesday. Another NW swell train will move into the area Tuesday afternoon.
