As of this morning a ridge of high pressure was still arcing over the Western U.S. This produced the surface high pressure and offshore winds and minimal marine layer fueling hot temps.
This feature is sliding east and by early next week an entirely different upper air pattern will dominate Western U.S. weather.
Onshore weekend flow will bring temperatures down gradually. Some marine layer at the coast should also return and it could be somewhat stubborn here it forms.
The trough over California Tuesday could even produce showers as a frontal system shoots thru Tuesday morning. It doesn't look well supplied with available moisture and after a very warm and dry preceding week I think it'll be tough to get more than a hundredth out here and there. The best chance will be in the Bay Area with diminishing intensity as the front extends south.
I think most of next week temps will be near seasonal norms as a general trough shape to the upper air pattern lingers. We will see varying amount of cloud cover thru next week with the onshore flow.
