Dangerously cold weekend ahead

Batten down the weather hatches.

The season's coldest air mass so far, and likely winter's best arctic punch, arrives this weekend. Seriously folks, the level of cold this weekend enters the danger zone. Wind chills to -40 degrees can freeze exposed skin in less than a minute.

The "Minnesota hunch" is back.

The core of the coldest air arrives Sunday. Temps of -15 in the inner metro core look likely Sunday and Monday morning.

The North American Mesoscale Forecast System's 2-meter temp loop vividly depicts the subzero invasion. Blue is cold, purple and unnatural colors on the maps mean subzero weather trouble.

60 subzero hours

That still seems about right. Is there a Netflix binge that long?

Get your errands done Friday and batten down the weather hatches this weekend.
