Additional snowfall for tonight

Total snowfall accumulations of around 2 to 4 inches are expected tonight in higher elevation in Duluth, with a trace to 2 inches in lower elevation, although I’m leaning more toward trace amounts more than 2 inch amounts in lower elevation tonight.

It took forever for the dry air to saturate today in the Twin Ports which is why the snow or rain started later than what was expected by a good 6 hours or so, but eventually the dry layer was kicked out thanks in part to Lake Superior which helped moisten the atmosphere, plus additional moisture/lift from the low/trough approaching from the Rockies.

Just your ordinary day in 2020 as a plume of wildfire smoke lifts northeast out of northern Colorado and into Minnesota and Wisconsin where it mixed in with snow and sleet across parts of the area today. Reports of a brownish tint to the snow cover in some areas due to this wildfire smoke today.
