The first wave of arctic air settled across the Northeast, while a new blast of arctic air gathered momentum over the Canadian Prairies on Friday.
This wave of frigid air will race across the Midwest on Saturday with eyes for the Northeast. AccuWeather.com RealFeel® Temperatures are forecast to plunge well below zero.
According to AccuWeather.com 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 or where electricity is knocked out due to the blizzard in New England."
Temperatures across the Midwest on Saturday will fail to reach the single digits from Fargo, North Dakota, to Minneapolis and Marquette, Michigan. High temperatures may fail to get above zero across northern Minnesota and North Dakota. The air will remain frigid into Sunday.
For any individual not properly dressed during these cold air outbreaks, they run an increased risk for frostbite and hypothermia.
According to AccuWeather.com Senior Meteorologist Alex Sosnowski, "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."
A slight break in the cold for some areas of the mid-Atlantic and Northeast will occur on Saturday ahead of a storm system that will bring blizzard conditions to New England during the weekend.
The second wave of arctic air will build into the East in the wake of this storm system on Saturday night and Sunday.
Record low temperatures may fall on multiple dates in the Northeast and South.
In the South, despite bright sunshine, locations from northern Mississippi, Alabama and Georgia will have high temperatures only in the 30s during the second half of the weekend and into early next week.
"The air will get cold enough in northern Florida to bring the risk of damage to unprotected sensitive fruits and vegetables during a couple of nights through Sunday night," Sosnowski said.
"Be sure to wear extra layers when going outside and bring your animals indoors to keep them protected from the arctic air," Lada said.
Yet another wave of arctic air will build across the Midwest into early next week and will move across the East. The cold wave next week will follow behind a storm with snow and ice in the South hitting on Monday into Tuesday. The same storm could swing up and hit part of the Northeast at midweek.
According to AccuWeather Meteorologist Ben Noll, "By the middle of next week, the cold will dive into areas from Texas to the Carolinas that have yet to experience the winter chill this season."
Because of the more southerly momentum with the arctic air next week, freezing temperatures could dip to parts of the Gulf coast and central Florida.
The momentum of the arctic air through this weekend is directed southeastward with the Northeast states in the direct path. Next week's blast will be focused southward across the Mississippi Valley and lower Plains.
