LAKE COUNTY, Calif. — Parts of the North Coast, including northern Lake County, are under a hazardous weather outlook due to chances of frost this week, with the potential for thunderstorms also in the forecast along with high winds in other parts of the county.

The National Weather Service issued a frost advisory for Wednesday morning and also for frost conditions expected Thursday and Friday morning.

The area in Lake County expected to be affected is north of Upper Lake, including the Mendocino National Forest and Lake Pillsbury.

During the day on Wednesday and on Wednesday night, that area also is forecast to have double-digit winds — topping out at more than 20 miles per hour.

On Thursday, there is a 20-percent chance of showers and thunderstorms after 11 a.m.

Conditions in that area are forecast to have daytime highs in the low 60s and nighttime temperatures that drop into the high 30s.

Temperatures are expected to warm up as the weekend arrives, with temperatures during the day rising into the mid-70s and nighttime temperatures reaching the mid-40s.

Elsewhere around the county this week, in Kelseyville, patchy frost is expected on Wednesday night and into Thursday morning.

On Wednesday, the south county could see winds of more than 20 miles per hour during the day and up to 44 miles per hour at night, when wind gusts could hit 55 miles per hour.

On Thursday night, south county winds are forecast to be around 16 miles per hour, with gusts of up to 21 miles per hour.

South county temperatures are predicted to rise into the mid 80s by early next week, with nighttime temperatures reaching about 46 degrees, the forecast said.

During the same time frame, the rest of the county is expected to see daytime temperatures in the high 70s with temperatures ranging form the mid-40s to the mid-50s at night.
