Waves of arctic air will bring the lowest temperatures and the harshest conditions of the winter from late this week through the middle of the month.
The arctic air will be pushed along by
a couple of Alberta Clipper storms with rounds of light snow in parts of the Midwest and the potential for a couple of heavy snow events in part of the coastal Northeast.
In perspective, the benchmark low, or the coldest it has been thus far this winter, in New York City was 8 F, on Jan. 8. On that same day, the temperature dipped to minus 2 F in Detroit, minus 1 F in Boston, 11 F at Atlanta and 12 F at Washington, D.C.
Like the frigid air during early January, the waves of arctic air moving in could bring disruptions to some of the trains in the northern cities. The prolonged cold penetrating deep into the ground could also cause water main breaks from the Midwest to the Northeast.
According to AccuWeather Meteorologist Brian Lada, "The combination of frigid air will not only be painful to endure for short periods of time outdoors but can bring life-threatening conditions for those not properly dressed."
The dangers will range from difficulty breathing to frostbite and hypothermia.
The first blast of arctic air will sweep from the Midwest to the Atlantic coast through the end of the week.
During multiple days, temperatures will not climb above zero F in northern Minnesota and part of northern Michigan.
While on the coldest days temperatures will climb into the single digits and teens from Minneapolis to Chicago, Detroit, Pittsburgh and Boston, AccuWeather RealFeel® Temperatures will be below zero for many hours on multiple days. Actual nighttime low temperatures will dip below zero on occasion.
Comment: In January, an extraordinary amount of snow was dumped all over the world. It looks like February might do the same.
