Extreme cold to grip eastern U.S. next week

Possibility of sub-zero wind chills Tues. night

If you thought the cold early this week was bad, just wait until next week.

We've been talking about it in our forecasts for days, but let me provide some specifics...

* The brutal cold will first arrive in the upper Midwest Saturday. The front ushering in the cold blast and its associated low pressure center is forecast to produce a blizzard in Minneapolis with one to two feet of snow possible Saturday along with winds over 25 mph and plummeting temperatures. Wind chills Saturday night may drop as low 30 below zero. By Sunday, the high in the Twin Cities may not rise above zero.

* By Monday into Tuesday, the core of the cold will reach the Great Lakes and Ohio valley. Chicago's high on Monday is forecast to be near 15 with wind chills Monday night 10 degrees below zero. Detroit will face similar conditions.

* The cold will bleed toward the East Coast starting Sunday night, with the worst of it in arriving Tuesday and Tuesday night. Although the cold air will not be as potent as it had been in the Midwest, the entire I-95 corridor from D.C. northward will have sub-freezing highs and lows in the teens. The wind chills will make it feel much colder. Conservatively, it looks like sustained winds of 20 to 30 mph with gusts over 40 mph begin Monday and may not relent until late Wednesday (especially toward New England). Wind chills at night will dip near or below zero in all the big cities.

Here's a look at what the D.C. metro region may face each day:

Monday: High 29-33, wind chills in the teens

Monday night: Lows 12-20 (suburbs to city), wind chills from 5 to -5.

Tuesday: High 25-29, wind chills in the single digits and teens.

Tuesday night: Lows 10-18 (suburbs to city), wind chills -10 to 0.

Wednesday: High 27-31, wind chills in the teens.
