We saw a lot of morning marine cloud cover today and while it cleared inland and at the coastal valleys there were a lot of beaches that didn't clear or clear fully.
This will continue this weekend with lighter beach winds. Winds help to mix the coastal clouds out, higher winds generally mean faster clearing.
One place that looks breezy in the afternoons will be the interior with 15-20mph winds this weekend.
In terms of temperatures, beaches will be in the 60s this weekend with the coastal valleys in the 70s to about 80 and the interior valleys in the lower 90s.
There will be a weather transition next week. This weekend there is an upper level trough to our east which will produce these mild conditions. Next week a ridge builds over The West.
At first it is just a slow temperature transition upward but by late-week and into next weekend it appears we will be on the backside of the upper level ridge. This can signal some southerly flow of muggy air. Models are showing not only warmer daytime highs but also warmer lows and higher dew points later next week. I wouldn't call it a heatwave but I think you'll notice the difference.
