Remarkable historic cold occurred last night. Temperatures dropped -3 to 10, but this occurred even as temperatures were on the rise part of the night.
If it would have remained clear & calm, widespread below 0 temperatures would likely have occurred.
Cold of this magnitude this early has never been seen in the record data set at West Lafayette (since 1879) & much of the area.
We have never been at or below 7 prior to November 15 before. The earliest was 7 November 8, 1991.

Some spotty snow showers will pass later this evening to early tonight, mainly in north half. Some patches of light freezing drizzle may also occur.
Dusting to thin coating of snow is possible north. A trace of freezing drizzle is possible in pockets over the viewing area.
Looks dry & gradually warmer right up to mid next week with frequently breezy to windy conditions.
Arctic air will erode............
Bursts of nice warmth will be interspersed with brief cool-downs late November.
Central & East look mild in early December, but there will be bitterly-cold air re-charging from Alaska & the Yukon to British Columbia.
I also think there should be more blue painted in the western U.S. on this map for early December.
So, colder West, warm East & bitter cold developing in western Canada to Alaska.
Late November through early December looks wetter than normal here.
This above normal precipitation will line u pfrom the Far West & Intermountain West & then Texas to Indiana & western Ohio.
Drier than normal southeast Georgia & Florida to the Northeast as warm upper ridge exerts its influence.
It should turn much coler after mid December, it appears with increasing winter storm risk.
