 at once. That doesn't happen very often, at least not lately.

Picked up 1.5” from the lake. Still getting occasional snow showers but it’s compacting faster than it can accumulate. 4” snow depth. Savoring it before the torch.

Dropped down to -2 this morning, the lowest temp of this season so far. 

Hasn't been our month for a lot of sun so far, but today happens to be the sunniest day of the month.

Nice mood flake day with a layered 10” on the ground to appreciate.

Right under the center of the high, it looks like. Assuming it stays above -14 before midnight, Champaign had a 1/-14 high/low today, which is a -36.5F departure from the 1991-2020 normal of 37/23.

The -14 low is the coldest temp on record for so early in the season, and records go back more than 130 years. Until today, there were only 2 days in history with a -10 or colder temp on or before December 14th:

12/10/1917: -10

12/11/1917: -12
