Monday evening forecast – Nov. 11th
Coastal clouds will continue to clear into the afternoon, and temperatures will be a few degrees above normal. Expect low clouds and fog to push inland from the coast tonight. Temperatures Tuesday will be warmer as some offshore flow develops, but additional clouds will bring cooler near normal temperatures for the end of the week.
Monday night conditions will be mild with increasing clouds and temperatures along the coast primarily in the 50s. In the valleys it will be a tad cooler than that with temperatures in the 40s.
Tuesday we will start off with cloud cover and by the afternoon we expect a good amount of sunshine and mild offshore winds. Temperatures on Tuesday will be above average in the mid to upper 70s along the coast and 80s inland.
Northeast winds will push warmer air into all areas below the mountains for Tuesday afternoon. Still expect a marine layer up to 1500 feet deep to bring a return of low clouds and fog to coastal and nearby valley areas later tonight and early Tuesday. The offshore flow will push the clouds off the coast earlier than today, but we don't anticipate northeast winds all the way down to the ocean. There will continue to be brief critical fire weather conditions where northeast winds occur in combination with humidities only 8-15 percent across the mountains and interior valleys.
High pressure ridge overhead on Tuesday will begin to shift eastward and weaken on Wednesday. Temperatures will begin to trend downward due to weakening offshore flow and reversal to onshore flow across most areas by the afternoon.
Thursday will be one of the coolest days of the week as a weak upper level trough passes through southwest California. High temperatures will run a solid 5-15 degrees cooler than Tuesday. There should be plenty of clouds, especially nearer to the coasts along with breezy southwest winds.
Temperatures will remain on the cool side with onshore flow for Friday, then a warming trend kicks in by next weekend with offshore pressure gradients getting stronger.
