Big Snow Mountains, Ho-Hum Valleys

video preview image

A powerful winter storm is hitting Northern California…and spilling over into Southern Oregon’s Mountains…as well as the Klamath Basin.  Snow levels remain above 3,000 feet, but with heavy precipitation flowing up into the Mt. Shasta area and the mountains of Northern California, serious accumulations are expected overnight and tomorrow morning above 3,500 feet.  Travel will become difficult from Black Butte Summit to Mt. Shasta and possibly Dunsmuir…definitely over on US 89 to Snowman’s Summit.

Other travel problems will develop on Highway 97, especially north of Klamath Falls…as well as over Lake of the Woods, Highway 66 and of course the Diamond Lake area.  Light accumulations of 1 to 3 inches will fall through much of the lower elevations of Klamath and Lake Counties, but the mountains and near Chemult will see 3 to 6 inches.

Over the Cascades, expect 4 to 9 inches overnight and by noon on Wednesday…while the Crater Lake and Diamond Lake areas are likely to record 8 to 12 inches.

Mostly light showers are expected in the Rogue Valley near Medford, under a “rain shadow”, due to the southerly flow that leaves much of its moisture on the Siskiyou mountains.  Heavier showers are falling in the Grants Pass and Western sections of the Rogue Valley, the Illinois Valley and northward into Douglas County.  The Coast has recorded several inches of rain, with heavy snow above 3,500 feet.

Some snow may fall briefly Thursday morning to as low as 1,400 feet in the Rogue Valley, but it will be light and a non-issue.  After morning showers Thursday, improving weather will move in by afternoon.  This will be followed by high pressure, warmer temperatures Friday, Saturday, Sunday & Monday.  There may be a small storm lurking for the middle of next week, but it is way too early to make a determination.  In the mean time, 60 to 65 for daytime highs in the Rogue Valley over the weekend, under lots of sunshine!
