Good morning with your US #RoadWeather. Ice on the roads this morning on I-80 in Wyoming at Sherman Hill, I-84 in Oregon at Deadmans Pass, and then snow and ice cover for a lot of I-90 and I-94 in the Dakotas and Montana.
Most of that was pretty light stuff (heavier in Wyoming) but all is moving out today and the sun will be out.
But the real story is developing further east with Lake Effect Snows taking hold. Conneaut OH saw snowfall rates of up to 3" (7.5cm) per HOUR last night in the heaviest band for a couple hours. I-90 is defacto closed there due to accidents. Similar snow in west central Michigan, though about half the snow totals
That initial blast cools off, but sets up with a different windward direction tonight. Buffalo New York will be expecting an area of greater than 4 FEET (1.2m) of snow through this weekend in one area, and a widespread area of up to 2 ft. (0.6m). Similar snowfall for Watertown NY area.
Full truck restrictions are in place for I-90 starting at 4pm tonight and continuing indefinitely. Last time they got this much snow, I-90 was closed about 4 days. NYDOT appears much more prepared this time, but we'll see what actually happens. You just can't physically move that much snow - especially once a few cars get stuck.
