A freeze watch will be in effect for the San Joaquin Valley late Thursday night into Friday morning, with temperatures dipping below freezing in most Valley areas, the National Weather Service in Hanford said.
A cold-air mass will settle over Central California, and Mono winds over 60 mph are possible in the southern Sierra Nevada and foothills on Thursday night and Friday morning.
Mono winds are a localized wind that blows across the western slopes of the central Sierra Nevada and into the foothills below from the northeast, according to the National Weather Service. The name derives from Mono Lake, because the winds blow into the central Sierra from the direction of lake.
The strongest gusts this week are expected through passes and canyons from Yosemite National Park to Kings Canyon National Park, the weather service said.
Western Merced County, including Los Banos, is among the areas expected to see below-freezing temperatures of 28 to 32 degrees late Thursday night into Friday morning and again Friday night into Saturday, the weather service said. The below-freezing temperatures were forecast to last from two to five hours Friday morning and four to eight hours early Saturday. Temperatures in Merced those nights were forecast to be near freezing or slightly above.
Residents are advised to provide shelter for pets, protect plants and wrap exposed pipes in preparation.
