I have been out in this kind of weather. Evanston, WY is the worst.. at about 7200 feet and the wind blows so much the trees all lean to the east. It can be miserable and dangerous.
That is when the ice crystals/snow feel like needles on your exposed skin. After this arctic blast passes, the predictive models are showing a massive area with -40 F’s developing in north central Canada. We will have to hope the jet stream keeps that next blast out of the US.
