This evening a cut-off low that has been sitting off the southern California coast will be moving north into our region and with it an increased chance for thunderstorms for northern California and east of the Cascades. We’ve already seen one thunderstorm make it into Lake county but it collapsed before it really impacted Lakeview. The threat for isolated thunderstorms will persist into this evening with the favored spots being Modoc and Lake county but can’t rule out a thunderstorm making it as for east as Klamath and east Siskiyou counties. No thunderstorms will climb over the Cascades and head into the Rogue Valley tonight, but that changes as we head into the weekend.
An upper low from the Gulf of Alaska will settle over the Pacific Northwest starting tomorrow which will act to bring much cooler temperatures to the region, breezy winds at the coast and along and east of the Cascades. Temperatures will actually drop to below normal for most of the week before we warm back up this weekend. This weekend will also see a more widespread threat for thunderstorms in the late afternoon and evening Saturday, Sunday and potentially Monday. The timing of this next low that will dive into the Pacific Northwest this weekend will determine how quickly and how late we see thunderstorms. Some weather models hold the system off until Sunday and have it linger Monday, while others have it move in more quickly on Saturday and out of here by Sunday night. Stay tuned to Newswatch12 for the latest updates on this Father’s Day thunderstorm threat.
