What is the coldest temperature ever recorded in Wisconsin?

Answer 1

The lowest minimum temperature ever recorded in Wisconsin was on February 2nd and 4th of 1996, when a temperature of -55 F was recorded at Couderay, Wisconsin. Incidentally, that is the record for the coldest temperature ever recorded in the US, east of the Mississippi River. Now, strictly speaking, that would have been the coldest night in Wisconsin on record. I couldn't find the lowest maximum temperature record for Wisconsin, but I did find that the high temp in Eau Claire on February 2, 1996 was -19 F. That's a pretty cold day, even by Wisconsin standards.

Answer 2

The coldest temperature that was ever recorded in Wisconsin was minus 55 degrees Fahrenheit. This was in 1996 on February 2 and February 4.
