Hot temperatures are expected to build Sunday into mid-week as high pressure continues to build across California.
Temperatures will warm to triple-digit levels inland, possibly breaking daily heat records on Wednesday and Thursday. Paso Robles could see daytime highs close to 110 degrees.
In coastal valleys, daytime highs will reach the high 80’s to low 90’s. Onshore winds will bring a cool air mass to the coastal valleys during the afternoon hours. Beaches will see temperatures hit the mid-70s.
High pressure is also expected to bring in strong northwesterly winds along the beaches, reaching up to 40 mph. Advisory-level sundowner winds are possible as early as Sunday evening and likely by Monday and Tuesday, mostly in Santa Barbara County locations.
A fire weather watch will be effect late Tuesday afternoon through Thursday morning for the Santa Barbara County mountains and south coast due to the combination low humidity and hot temperatures.
An excessive heat watch will be in effect Tuesday through Thursday for San Luis Obispo and the Santa Barbara County coast. Montecito, Santa Barbara, and Carpinteria will see an excessive heat warning from Monday to Tuesday.
