Friday evening forecast – Dec. 13th

An approaching low pressure system will bring cooler, breezy weather to the region. There will also be a chance of light rain tonight. This chance moves to the mountain areas Saturday morning, with snow developing later. Dry and warmer weather is expected Monday and Tuesday.

Friday we enjoyed beautiful weather some areas saw patchy fog other areas had pure sunshine creating a wide array of high temperatures.  The strong onshore 

trends were a big reason for this and temperatures definitely trended cooler for coastal areas and some of the valleys too.

A weak cold front is approaching from the north and this will further increase onshore flow and cause the marine layer to rapidly deepen later tonight into Saturday.  This could bring us drizzle or even light showers, especially along the foothills.  Increasing winds will help clear skies out along the central coast south through Ventura

County by afternoon. Several degrees of cooling all areas Saturday as a result with highs just in the low to mid 60s for coast/valleys.  Slightly warmer across southern Santa Barbara County due to downslope flow there.

It will be a breezy afternoon in many areas with marginal advisory level winds. Even stronger winds expected Saturday night into Sunday morning, especially southern Santa Barbara County with sundowners.

Sunday is expected to be mostly sunny in most areas with temperatures still a few degrees below normal.

The ridge building in from the west should bring us at least a few degrees of warming Monday with the warmest temps along the Ventura coast.

Santa Ana winds are expected Monday and Tuesday

Still a chance of rain Wednesday into Thursday with best odds across San Luis Obispo and Santa Barbara  Counties. Rainfall amounts probably under a half inch either way, and possibly much less.
