This storm is what meteorologists call a “Meteorological Bomb” or “Bomb Cyclone.” This is because the atmospheric pressure drops at least 24 mb in 24 hours. This rapid drop in atmospheric pressure causes “explosive,” rapid strengthening. In this case, about 30 mb in 15 hours. The lower the pressure, the stronger the storm.
The worst snow will be across the Cascade passes, where there is a winter storm warning. The Willamette Pass could see 12 to 24 inches of snow with gusts near 50 mph, which could lead to new blizzard conditions at times. The Coast range and foothills will be closer to 2 to 6 inches, with gusts 25 to 35 mph. Travel will not be advised this afternoon through early Wednesday morning in the Cascades.
Eugene/Springfield as well as Roseburg will likely see the least amount of snow and most of the rain during the day. Overnight, snow is expected to fall to the valley floor with 1 to 3 inches is possible on grassy surfaces around the Eugene/Springfield area with less on the roadways. North of Eugene, only a trace to 1 inch will fall.
Wind will also be big factor along the southern Oregon coast, where a high wind warning is in effect. The strongest winds for the headlands and beaches south of Bandon will be in excess of 75 mph, and in some areas up to 100 mph. Strong winds will push inland later, bringing gusts of up to 45 mph to Roseburg.
Snow showers will decrease late tonight into early Wednesday morning. Snow showers will likely linger later in Douglas County with light accumulations in the Cascades.
Behind the storm, high pressure will bring sunshine but cold temperatures. High temperatures on Thanksgiving will be in the 30s. These cold temperatures will likely linger into Saturday. That means the Civil War game will be very cold. The next system will arrive on Sunday, which could bring more rain and snow to the region.
