I'm glad I wasn't swimming in Lake Michigan last night

I mighta gotten chilled:

While perhaps not record-setting, the temperature change in southeast Wisconsin was remarkably chilling, given the accompanying wind.

"If you consider the average wind chill around Southeast Wisconsin this morning of around -25 to -30, you could argue that this temperature drop was far more significant than the 50 degrees," said Michael Westendorf, a meteorology professor and director of Innovative Weather at UWM . "Go from 46 with no wind in the afternoon to -4 with a -25 wind chill, makes it more of a 70-degree temperature drop..."

It's the wind,not the cold. Yep. Just like the humidity.
