MENDOCINO Co., 8/21/24 – Parts of Mendocino County experienced light precipitation this past weekend. The rain must have enjoyed its rare and brief visit in August, because precipitation is expected across the county starting Thursday night.

The cause? A rare cold front moving down from the Alaska Panhandle.

For this reason, the National Weather Service Eureka (NWS Eureka) predicts that precipitation is likely in some areas starting Thursday evening. Rain chances are highest on Friday. Thunderstorms are possible in some areas. It will be dry through Saturday evening. Temperatures will be unseasonably cool.
