High pressure has been driving the recent hot weather. Wednesday marked another 100+ day for some of the interior valleys and even coastal temperatures were above average despite ample high cloud cover. Well, that high pressure will start to weaken Wednesday as the upper level ridge driving it movies to the east.
Onshore flow will return and Wednesday and we should have some marine clouds at beach communities. Modeling shows a much more substantial marine deck moving in Wednesday afternoon. What does this mean? Beaches get immediate cooling Wednesday but coastal valleys and interior valleys will still be above average. Thursday the coastal valleys will get more of that cooling with temps returning to average or even below average. Inland temperatures will still race into the mid-90s on Wednesday and Thursday with Friday thru Sunday temperatures in the upper 80s and lower 90s. Still slightly above the average but at least not 100.
Not much change over the weekend into early next week. Strong onshore flow will continue with breezy conditions at the coast.
