LAKE COUNTY, Calif. — As Labor Day weekend arrives, forecasters are predicting a late-summer hot spell.

Over the past week, cooler temperatures have prevailed in Lake County. There were even small showers during that time.

While temperatures are forecast to be warmer this week, they will not reach the levels seen in July.

In an update on the holiday weekend weather, AccuWeather expert meteorologists said to expect temperatures that run up to 10 degrees above the historical average.

AccuWeather Meteorologist Grady Gilman says some areas are experiencing a 35-degree temperature swing in the span of one week.

The warm pattern follows cool conditions that affected much of the region this past weekend, which included some snow for the high country of the Sierra Nevada and Cascades, Accuweather reported.

“An unusually strong storm brought unseasonably cool weather to much of the West coast late last week,” explained Gilman. “Temperatures were 20-25 degrees below historical averages and even set daily record low maximums.”

The high temperature in Sacramento failed to reach 80 degrees on Friday, marking one of the coolest August days on record, Accuweather reported.

“A noticeable warmup will begin early in the new week and peak midweek as an area of high pressure builds in,” said Gilman. “Some locales can see an increase in afternoon high temperatures of up to 35 degrees in just a handful of days.”

The National Weather Service reported that conditions this week will peak in the low 90s during the day and the low 60s at night.

By Labor Day, daytime temperatures will drop into the low to mid 80s and the high 50s at night.
