A ridge of high pressure looks to expand across The West. Temperatures were already nearly 100 on Monday in the deeper interior valleys and the growing ridge is only getting stronger and larger. This will compress the marine layer and only produce light onshore flow at the beaches and near coastal valleys. In other words, everyone should warm some but the changes will be less remarkable at the beaches and near coastal valleys.
Tuesday Paso Robles should hit 100 with Wednesday and Thursday having 100-105 degree potential.
Expecting a more shallow marine layer this evening, and through Thursday, as the higher heights build and result in decreased low cloud coverage.
I think beaches will be in the upper 60s and lower 70s the next few days. Coastal valleys will range from the 70s to mid 80s.
This ridge holds until Friday and then completely collapses for the weekend for temperatures to drop to below average temperatures, perhaps as much as 10 degree below average. Some minor warming begins again early next week.
