A warm ridge of high pressure that is currently over the state will really bring the heat Tuesday, especially for the inland valleys.
Daytime highs for the interior valleys and mountains will range from the mid-90s to low 100s and as a result, a heat advisory has been issued for those areas in San Luis Obispo County. The advisory will take effect at 11 a.m. and last through 9 p.m., although, with excessive heat in the forecast through next week, more heat advisories are expected to be issued over the coming days.
The coastal valleys are also warming up Tuesday with daytime highs expected to range from the mid-70s to low 80s. The beaches will be the place to beat the heat with temperatures staying close to the low to mid-70s Tuesday. Marine layer will fill in over the coast and coastal valleys in the morning, but conditions will clear up by early afternoon.
Winds will be breezy at times Tuesday ranging from 10-25 miles per hour by the afternoon. However, onshore flow is expected to decrease Wednesday and bring even more sunshine to the area.
