LAKE COUNTY, Calif. – Northern California is expected to see several days of hot temperatures in the lead up to the official arrival of summer.

The National Weather Service issued a heat advisory for parts of Northern California – including Lake County – from noon on Saturday through 8 p.m. on Tuesday due to an anticipated extended period of hot weather with near-record temperatures.

The specific Lake County forecast calls for temperatures in the low 90s on Friday, the mid 90s on Saturday and topping the century mark on Sunday, when the daytime is expected to be near 105 degrees.

Monday and Tuesday also are expected to see daytime temperatures at or just over 100 degrees, rolling back slightly into the high 90s through the rest of next week.

Throughout that period, nighttime temperatures are forecast to range between the low and high 60s.

Lake County Fire Protection District Chief Willie Sapeta asked people to exercise caution and be fire safe as temperatures rise.

Sapeta and his crews were on the scene of a wildland fire in Clearlake on Thursday afternoon, and he said vegetation is extremely dry and prone to burning at this point.

He reminded people not to mow grass after 10 a.m. and to report any smoke as soon as they see it.

Sapeta also urged community members to be careful about their own health in the heat. He said to stay hydrated and to make sure pets are adequately protected from the heat.
