First Arctic front continues to race through with gusts 32-43 mph measured so far.

The cold air is coming in so quickly that the dense, heavier cold air is flipping the milder air of earlier on top of it, causing a line of wind-driven, gusty freezing rain & drizzle along & immediately behind the front.  This actuall caused a diffuse shelf cloud seen along the cold front.

Rather than a line of snow squalls, it is sheets of light freezing rain & drizzle.

This, combined with the flash freezing underway is & will continue to causing rapid icing on roads, sidewalks & trails.  Bridges & overspasses are & will freeze first over the area.  Be careful out there!

The wall of teens & 20s is roaring in, replacing the thawing mid to upper 30s.

Low will drop to near 0 tonight with quick rise to 7-15 tomorrow, then drop to below zero tomorrow evening.  Wind chills will drop to around -17 by tomorrow evening.

Scattered snow flurries & snow showers are possible at times tonight-tomorrow with potential of burst of brief heavier snow tomorrow evening with secondary Arctic front.  1" of snow or less is expected tonight to tomorrow.  There could be an isolated location or two that exceeds 1".

Tomorrow night to Thursday morning look bad with the cold.  Wind chills -50 to -30 & air temperatures -25 to -15 will dominate with sustained winds 15-22 mph with gusts to 30 mph at times.  Wind chills only take into consideration sustained winds, not gusts.  So, gusts could see even lower wind chills.

Frost bite of exposed skin will occur in 6-14  minutes with this kind of cold.

Rare Wind Chill Warning is up viewing area-wide to Thursday morning.

If you have to venture out much at all, remember the 2-3-2 rule with two layers of pants, three thick layers of the torso & two layers on the face & head.  Thick gloves & thick waterproof boots are needed.

As temperatures rise late Thursday through Thursday night, clipper with potentially 1-2" of snow will pass.

Flash thaw will occur Sunday-Monday with 36 hours of warmth, then temperature tank.  Sunday-Monday could feature ice jams & sudden big cracks & potholes in roads. 

Second flash thaw, then potential second round of major cold could occur in the second week of February following potential winter storm or two.
