LAKE COUNTY, Calif. – The National Weather Service in Sacramento has issued a special weather statement for Lake County and much of Northern California for Tuesday, with high temperatures expected to reach above the 100-degree mark for the first time in August.

After an unseasonably cool and pleasant weekend, temperatures climbed back in to the high-90s on Monday, with areas in Middletown and Kelseyville reaching the century mark, according to the Western Weather Group.

Tuesday and Wednesday should be even hotter, according to the National Weather Service, as temperatures around Lake County are forecast to reach into the 100s.

Overnight Tuesday, the thermometer will only dip to the mid- and upper-60s, the National Weather Service predicted.

On Wednesday, daytime highs will cool by a few degrees, but still will hover near 100 degrees due to the continuing high-pressure system, forecasters said.

The National Weather Service said that daytime high temperatures will begin to decrease on Thursday. At that point, daytime temperatures will return to the average highs in the lower 90s, according to the Old Farmers' Almanac, and the cooling trend continues through the end of the week.

Overnight lows also will trend downward, forecasters said, with lows in the mid-50s expected on Friday morning.
