Arctic blast this weekend to bring life-threatening wind chills, subzero highs
By: The Weather Channel
The last in a short series of bitterly cold blasts of arctic air is plunging into the Midwest this weekend, bringing life-threatening wind chills and the lowest air temperatures of the season. The cold air will lose some of its bite as it arrives in the East and South early in the week ahead.
Parts of the Dakotas, Minnesota, Iowa and Wisconsin may see subzero highs this weekend. But even this cold blast will not be extreme enough to break more than a few daily low-temperature records, since this is the coldest time of the yearclimatologically speaking and many past cold waves have been even more severe.

The renewed blast of chill follows a brief but impressive warmup that brought highs in the 60s as far north as Missouri Thursday.
Forecast Highs Saturday to Tuesday
Below is an overview of the next wave of cold air that will progress south and east across parts of the country, followed by the forecast temperature maps.
Saturday: A large chunk of bitterly cold air will be in place in eastern Montana, the Dakotas, Minnesota, Iowa and western Wisconsin. Highs will be 15 to 30 degrees below average. Subzero highs are expected in North Dakota and northern Minnesota.
Sunday: Much of the Midwest will see daytime highs 15 to 30 degrees below average. Lows in the teens and 20s below zero are likely in the Upper Midwest and northern Plains. Subzero highs are expected in parts of the Dakotas, Minnesota, Iowa and Wisconsin. Daytime highs may be below zero into parts of Nebraska and southern Iowa, where official 24-hour highs will probably be above zero but occur in the wee hours of the morning.
Monday: A swath from the Dakotas to the western Great Lakes will see subzero morning low temperatures. Highs will be 10 to 25 degrees below average from the Midwest to the Mid-Atlantic states.
Tuesday: Temperatures moderate slightly from the Upper Midwest to the Great Lakes. Temperatures will remain some 8 to 15 degrees lower than average in much of the East.
Low temperatures Sunday through Tuesday morning.
The wind will make this cold much more dangerous. Unlike some bitterly cold mornings, when temperatures plunge under a clear, calm sky above a deep snowpack, this batch of subzero temperatures will come screaming through on a vicious northwest wind.
Map above shows the forecast for what it will "feel like" outside early Sunday morning.
This will likely result in wind chills – the temperature it feels like when wind blows across your exposed skin – reaching 40 to 50 degrees below zero Sunday morning over the eastern Dakotas, and parts of Minnesota. At these levels, frostbite can occur to exposed skin in as little as 10 minutes. According to the Grand Forks, North Dakota National Weather Service office, "the brutal cold will be a major hazard this entire weekend with life-threatening wind chills."
While we're unlikely to see many record lows, in a few places temperatures may reach levels not seen in at least two years.
For instance, Minneapolis-St. Paul may flirt with the minus-20 mark Sunday. The Twin Cities have not officially recorded a reading that low since Jan. 6, 2014. Only five days in the 21st century have reached 20 below zero at Minneapolis-St. Paul International Airport.
Sioux Falls, South Dakota, may also reach 20 below zero in this cold snap. If it does, it would be the coldest air to visit the city since Feb. 10, 2011. Only seven days have reached 20 below zero in this century for South Dakota's largest city.
Similar readings are expected farther north, but in those regions 20s below zero are far more common. For instance, as of Wednesday International Falls, Minnesota, had reached that mark 247 different days since the start of 2001, two of those just this month.
High temperatures may not rise above zero in Des Moines, Iowa, and Madison, Wisconsin, Sunday. That's only happened three times this century in Des Moines and four times this century in Madison, last occurring in each capital city on Jan. 6, 2014.This Week's Cold Recap (Jan. 10-12)
