Embrace the Burn
A Minnesota winter is a steep learning curve. I remember being baffled, horrified, then deeply impressed the first time I saw someone RUNNING in subzero cold. I had moved to a state populated by a race of attractive aliens with cold-weather superpowers.
Early on someone pulled me aside with good advice: "Don't hide in the basement or hibernate in front of the tube. Embrace winter! Put on some cross-country skis, take the kids skating, build a snowman. The best antidote is to throw yourself, headfirst into winter.
As long as you're properly dressed. I've been following the no-exposed-skin rule since reaching middle age and it will apply to everyone thru the first half of next week. Windchill advisories are posted; we may see 5 nights/row below zero - highs Saturday may hold below zero.
This may wind up being the coldest stretch since 2007. According to Pete Boulay, at the MN Climate Center, we enjoyed 10 nights/row below zero in February, 2007. The record? 36 nights/row below zero in 1936.
More deep breaths: 30s return in a week, and you'll be amazed how good freezing feels a week from today.
Yes, misery loves company. Freeze warnings are posted for Phoenix, even San Francisco. Most of America is shivering right along with us!

Future Radar. The animation below shows a wave of low pressure rippling along the edge of arctic air, sparking a band of snow and potentially paralyzing ice from Texas and Oklahoma into Arkansas, Kentucky and Ohio over the next 84 hours. Data: NOAA's 4km NAM and Ham Weather.
* Leading edge of bitter air sparks band of heavy snow and ice from northern Texas and Oklahoma into Arkansas and Middle Mississippi Valley and Ohio Valley over the next 36 hour. Very significant snow is expected from southern Illinois and southern Indiana into northern Kentucky and much of Ohio.
* Ice Storm Warnings posted from near Oklahoma City to Little Rock and Memphis for .25"+ amounts of glaze ice tonight into Friday.
* Enhanced risk of frostbite north central USA as wind chill values dip to -30F by Saturday morning.
Summary: We're still on track for a very significant period of heavy snow and ice, impacting the Southern Plains, Middle Mississipi Valley and Ohio Valley over the next 48 hours. This still will impact travel by land and air, with a high probability of power disruptions in some communities due to a heavy accumulation of glaze ice. Accumulating snow may extend into New England over the weekend, with a few slushy inches from D.C. to Philadelphia by Sunday, but confidence levels for East Coast accumulation is still quite low - we need to see more data. Meanwhile the coldest air in at least 4 years will create potentially dangerous wind chills and an enhanced frostbite risk from the Upper Midwest into the Great Lakes.
