Wednesday morning forecast September 30
The ridge of high pressure will continue to strengthen, as the marine layer weakens. This will keep temperatures hot, skies relative clear along with gusty winds. Wednesday and Thursday the area will receive peak heat for the week, reaching the triple digits in the valleys and the 80s to 90s for coastal areas. This will then bring the potential for record breaking heat through Friday.
Hot temperatures, dry conditions, and warm overnight lows create an elevated risk of fire. There is also a Heat Advisory in effect in Santa Barbara, San Luis Obispo and Ventura Counties through Friday at 8:00 pm.
Expect to see a major cool down Friday and into the weekend. Some areas may see a temperature change by over 10 degrees.
Clouds move back into the picture Sunday with the return of onshore flow. The marine layer will cool temperatures to around normal in coastal areas, but remain above normal by around 10 degrees inland.
