Winter Weather Advisory 2017 Excel.jpg

Snow levels will drop to between 4000 and 4500 feet Thursday night into Friday morning. Expect 8-12 inches of snow over the Cascades near Crater Lake with 6-8 inches as far south as Lake of the Woods and perhaps upper portions of Mt. Ashland ski road.

With cold air arriving, rain will change to snow east of the Cascades (primarily north of Highway 140). A few inches of snow are possible along highway 97 north of Chiloquin, up around Chemult.

Rain may also change to snow at Siskiyou Summit Friday, but accumulation should be less than an inch. Winter hazard products are in effect. After a break Saturday, another storm system will arrive Saturday night into Sunday. Snow levels will be lower – down to valley floors east of the Cascades and around 3000 feet over the west side and in northern California. This could bring accumulating snow to the higher passes like Siskiyou Summit at the CA/OR border and also near Black Butte Summit near Mount Shasta City. Stay tuned for more details regarding that storm! 

When driving in ice and snow, take it slow! Make sure to carry chains, food, water, blankets, flashlights, medications, and a fully charged phone when traveling. 

Be sure to check road conditions before venturing out.
