That's minus 110 degrees windchills. Now that's cold.

Mount Washington Observatory says that the air coming from Canada which is affecting millions will also break records for Mount Washington. The higher summits could break records, including the record low of -47. Might not be the time to take a hike.

There is a wind chill warning that will stay through Sunday. The air temps are bad enough, but it's the wind that is setting up historic lows. Plus, as this artic blast heads over the mountains, snow will develop. It will get pretty intense at times too! Snow squalls will drop a quick couple of inches and with the gusty winds, drifting is possible above the treeline.

Temperatures on Friday, February 3 will start around 25F below then fall throughout the day to around 40F below at sunset. When that sun sets, the temps start to plummet to around 50F degrees below zero. That would break the all-time low of 47F below. But then the wind. Ohhhh, the wind!

Winds will start around the 60-80 mph range on Friday then crank to 80-100 during the afternoon. They keep increasing Friday night to 110-115 mph with gusts up to 130 mph right into Saturday morning. Winds will peak and there could be gusts to 140 mph!

That's what the winds will be and the wind chills will be epic. Wind chills will be very dangerous, especially above the treeline. Friday morning wind chills will be around 70 below and drop to 90 and 100 degrees below zero by sunset. But the coldest air of this polar vortex will be Friday night. Temps drop and winds will be their strongest and wind chills will be between 100 and 110 degrees below zero. But as pointed out by the Mount Washington Observatory,

In the end there is no real difference between a wind chill of 80 below and a wind chill of 100 below in terms of impacts to the human body. Both values should be taken very seriously and can prove lethal.

They have to say this because people may not understand and could still want to hike! Anyone hiking with the warnings that we've all had for a week...well, they just shouldn't. Any tiny mistake hiking in weather like this could be fatal, and getting help would be virtually impossible. So maybe just sit back and make sure that there's plenty of wood for the wood stove.
