Winds pick up which could help clear marine clouds

At the coast some of the west-facing beaches have seen little clearing and as a result cool conditions most of this week.  Models are showing clouds moving back in overnight but show a little earlier pickup of the NW winds 15-25mph Thursday which should help clear the clouds a little better.  However the flow direction is onshore so temps will be on the cool to mild side.  Inland locations could get in on some clouds later tonight and early Thursday due to a trough deepening the marine layer.  Skies should clear quickly Thursday morning for temps to ultimately recover into the 80s. Beaches in the 60s and coastal valleys around 70.

Could see some weak sundowner winds tonight in the western portion of SB county but a better chance later Thursday.  This will help blow out southern SB county clouds.

Friday looks similar to Thursday.

Saturday high pressure should build for warming temps, especially inland back into the 90s.  Coastal valleys will be in the middle to upper 70s with beaches in the 60s and 70s with some night and morning clouds and partial clearing at some beaches.

Next week looks interesting.  Wednesday (the 4th) an upper air low drops into the Pacific NW which will put the Central Coast in a SW flow aloft.  This is typically a mild direction but the depth of the marine clouds could increase but could also be some sub-tropical clouds from projected hurricane activity in the East Pacific Basin.  This complicates a July 4th fireworks forecast for beach areas.  Right now I’d say I’d have to have clouds in the forecast due to light surface air flow, this could change.

After that a ridge of high pressure builds from the 4-corners region and expands west for what could be a run of hot weather inland and potentially for coastal locations as well late next week.
