A cut-off low off the southern California coast will be moving north tonight and tomorrow bringing a chance for isolated thunderstorms this evening and tomorrow afternoon for northern California and areas east of the Cascades. The favored spots are Modoc and Lake counties, but can’t rule out a pop-up storm in Klamath and Siskiyou counties. This disturbance will also act to bring more clouds to those areas as well as much cooler temperatures across the region tomorrow, although still unseasonably warm.
We’ll continue the cooling trend through Thursday as a trough from the Gulf of Alaska pushes into the Pacific Northwest. We’ll see a mix of sun and clouds for inland areas for the remainder of the week and more seasonable and even below normal temperatures! The coast and perhaps Douglas county and the northern Cascades could see some light showers late Wednesday and Thursday. Next weekend a cut-off low will develop over the region and we’ll see the chance for thunderstorms for all inland areas in the afternoon and evenings. For now it is a slight chance but we will continue to monitor the thunderstorm threat.
