Forecasters said temperatures will remain well above normal across inland areas through Saturday with little likelihood of rain.
However, chances of rain will increase late in the weekend and early next week as a trough of low pressure digs along the Pacific coast, the National Weather Service said.
In Lake County, rain is expected to come into the picture beginning on Sunday, with rain anticipated to begin in the morning.
Chances of rain are forecast to continue through Wednesday.
The Lake County forecast also predicts daytime temperatures into the high 70s through Saturday before dropping into the 60s. Nighttime temperatures will range from the low to high 40s.
