/Issued 5:29 PM CDT, Wednesday, October 10, 2018/
Precipitation continues to lift north across the Northland early this evening while the rain-snow line shifts slowly to the east.
Here’s my updated snowfall potential map for tonight. Use caution if you have travel plans tonight/Thursday morning especially across northern Minnesota as roads could become snow/slush covered and slippery tonight. Reduced visibilities are also likely due to the snow.

Forecast for northeast Minnesota and northwest Wisconsin
What A Storm! Certainly a memorable one especially in terms of the amount of lakeshore flooding and powerful NE winds that it produced today. One for the ages!
[Tonight] Low pressure was over central Wisconsin late this afternoon, the low heads northeast and continues to deepen tonight, the center of the low is forecast to be near the northeast tip of Lake Superior by dawn. Cold air will spread S/E across our area tonight as the low departs, will also get a wind shift from NE to NW, and wind speeds will come down just a bit from 30-50 mph early this evening, to 15 to 30 mph overnight. Occasional rain and drizzle will continue this evening in eastern Minnesota and northwest Wisconsin with areas of fog also likely while snow and mixed precipitation occurs in north-central Minnesota. The rain-snow line shifts farther south/east through the night as the low pulls away and colder air moves in.
Note: Looks like between Midnight-2 AM we could see the rain change over to snow here in Duluth, might be a little later if it changes at all below the hill though.
[Thursday] Very cold for mid October with highs only in the 30s to around 40 degrees; Normal highs are in the mid 50s! Still looks fairly cloudy once again, although we could see a few peeks of sun, but I wouldn’t count on a whole lot of sun on Thursday. Lingering flurries and snow showers should continue as well especially during the morning.
[Friday] Might get a little more sun on Friday but it still looks chilly with daytime highs only in the 30s to lower 40s.
