A warm front will pass through this morning warming temperatures to some of the warmest of the week and snow levels climbing to 4,500 feet. This will be short-lived though as a cold front will quickly follow bringing the heavy rain, snow and strongest winds. The heaviest precipitation will fall with the passing of this front between 5PM and midnight, most areas starting as rain with such high snow levels quickly turning to snow tonight down to 2,000 feet by tomorrow morning and locally down to 1,500 feet. Blowing and drifting snow may cause blizzard-like conditions at times. The National Weather Service says this storm will be in the top third of storms in terms of precipitation. We’ll see moderate to heavy snow at times, especially in the Cascades with the potential for one to two inches of snow per hour at times! If you must travel be prepared to run into hazardous winter travel, especially over the passes, including Highways 285, 62, 66, 140, US 395, US 97 and Interstate 5. The heaviest snow will likely fall along and north of Lake of the Woods, but we could see up to four inches on the Siskiyou Summit by tomorrow morning. Some other snow totals are below:
Tr-2″ on the valley floor. Snow will be falling in the overnight when roads are cold, so even at low elevations we could see snow accumulation on the roads.
3″-5″ between 2,000′-3,500′
6″-14″ in the Siskiyou’s, potentially 4″ on Sisikiyou Summit by tomorrow morning.
12″-18″ in the Cascades, and for some favored areas up to two feet!
For the coast expecting to see strong winds with gusts up to 50 mph, high surf with waves up to 25 feet, beach erosion and sneaker waves possible. A High Surf Advisory is in effect there until 10 PM Saturday. High profile vehicles may be impacted by the winds and should use extra caution.
If you must travel tonight be sure to check road conditions, carry chains and extra supplies and be prepared to run into hazardous driving conditions at times. Find more on what to carry as well as road conditions under the ‘Weather Links.’
