Three questions for Minnesotans, same answer: How cold was it yesterday? How cold is it today? How cold will it be tomorrow?
There's been no corner of the state immune from the subzero barrage that is not expected to let up until next week.
Add in some stiff winds, and that's enough for the National Weather Service to post a windchill advisory that warns that temperatures into the weekend will feel more like 40 below zero in some spots.
The Weather Service's windchill advisory was inspired by a mass of arctic air building over the Upper Midwest and moving in to west-central and east-central Minnesota. The worst of the windchill readings were forecast for Friday night and into Saturday morning.
By 7 a.m. Friday, Fosston in northwestern Minnesota bottomed out at 24 below. It seems that only the southeastern part of Minnesota evaded double-digit readings below zero. Austin was leading the way there, with minus 4, the Weather Service reported.
Otherwise, Park Rapids was reporting minus 21, Hinckley minus 13 and Staples minus 18.
In the metro area, Eden Prairie's mercury dipped to 9 below. Then it was minus 8 in Lakeville, minus 7 in Crystal and minus 6 in Lake Elmo.
Meteorologist Paul Douglas says the current cold snap may wind up being the coldest stretch since 2007.
