Temperatures are starting off much cooler in the Klamath Basin this morning, almost 25 degrees cooler than yesterday morning. The dense fog that blanketed the valleys yesterday has also let up with both Brookings and Medford reporting good visbilities to start the day off. Regardless, patchy fog and low lying clouds will sit in the valleys before eventually burning off.
Increasing clouds are anticipated today as a weaker disturbance moves in from the North. This will bring isolated showers to the region by late afternoon and early evening. The showers will taper off through the overnight hours and the first half of Friday will start dry.
By Friday evening, a cold & wet air mass will move in from the North, bringing widespread rain in the lower elevations and snow to the higher terrain. Snow levels will quickly drop through Friday evening and into Saturday. By Saturday evening they will be at 3,000’.
Mountain pass conditions will deteriorate through Friday evening, with accumulating snow expected above 3,500’ through Saturday. Showers will taper off into Saturday evening. Between 4”-8” of snow is anticipated in the Cascades, 2”-4” in the Siskiyous and 1”-2” in the Klamath Basin.
If you are traveling Friday or Saturday, throw the chains on your vehicle and be prepared for winter weather. It’s likely Siskiyou Summit, as well as the other passes (especially the higher passes) will have snow on them through this time period.
This will not be a significant rain event for the Valley, rain showers will be widespread Friday evening and become more scattered into Saturday morning, becoming isolated into the afternoon.
