Temps will still turn the corner as the week closes

Posted at 4:44 PM, May 10, 2023

As expected, the Central Coast had some sluggish warming on Wednesday the reason for this is the night and morning marine cloud cover and the significant afternoon onshore winds. A ridge of high pressure is building over the Central Coast inland temperatures will start to move first but ultimately by the weekend, everyone should see warmer conditions as the marine layer presence will be limited.

 

Thursday will still be a transition day for beaches and coastal valleys with daytime highs in the 60s and lower 70s but interior valleys will see daytime highs already pushing into the mid-70s to nearly 80 degrees.

The winds of this afternoon mixed out a lot of the low clouds but as they slow to night the marine clouds will form again. Overnight lows at beach communities will be in the mid-40s and low 50s with daytime highs Thursday in the low 60s.

 

Friday coastal valleys will see a significant jump in temperatures with mid-70s to upper 70s possible while interior valleys warmed to nearly 90 degrees. Beaches will also warm but by less. The warming trend continues Saturday with 70s and low 80s at coastal valleys and low 90s in the interior. Saturday we'll see peak conditions and some cooling is expected especially at the coast on Sunday and Monday with more marine influence back in the forecast. Inland temperatures also sagged but not by much only into the mid-80s. A little bit of warming resumes on Tuesday and Wednesday.

 

The warming will take place because of the amplification of an upper-level Ridge over the western United States. Once this ridge sets up the amplitude is so high that some return flow from the southeast could bring in some unstable air and scattered thunderstorms are possible at higher elevations in California over to the extended forecast. Local rain is not particularly likely I like to call it a non-zero chance, it's low but not zero.
