Incoming Arctic blast means frigid temperatures ahead

KNOXVILLE, Tenn. (WATE) - As an arctic blast makes its way into East Tennessee, some parts of the region won't see temperatures above freezing for four days or more beginning Saturday morning.

Our winter forecast months ago was hinting at a harsh start to the winter season. That's been playing out all December and it's ramping up even more as we roll into the New Year.

The best news about this next Arctic blast coming to East Tennessee is that it's a dry blast. Any snow should be light with only minor accumulations. 

So let's talk numbers. Our record lows around the New Year are all at or below 2º. So I'm not talking about breaking records. Despite records staying untouched, it's still be something you should be preparing for.  

Morning lows will dip into the teens for days. We've been through that before -- last January we hit the single digits once and the teens twice. The problem this year is the duration. We'll be dipping into the teens four straight nights: Overnight Saturday through overnight Tuesday.

Adding fuel to the fire (or ice to the igloo!) is the lack of a daily thaw. High temperatures will only hit the 20s and lower 30s. After Friday's lower 40s, some areas may not warm to above freezing until Tuesday. The Cumberland Plateau and the Great Smoky Mountains National Park won't see temps above freezing (32º) for four straight days.

That means if pipes freeze, you may be without water for days. Do what you can to prepare for this ahead of time. And don't forget proper housing for your pets!
