Bitter cold is forecast for the eastern half of the country through the weekend, with possible record lows predicted for Valentine's Day.
Millions of people from New England to Florida will be in the path of the latest Arctic blast. The Northeast will see single-digit and sub-zero temperatures as Cupid shoots his arrow: In New York, the wind chill could get as low as negative 15 degrees Sunday morning, forecasters said.
The Northeast will likely see its coldest temperatures of the winter so far, The Weather Channel reported. Subzero cold is also expected in parts of the Midwest, forecasters added.
Meanwhile, in the West, temperatures were soaring. In California and Arizona, it could get into the 70s and 80s, the National Weather Service said.
The dangerous cold had already set in in other parts of the country on Thursday. In northern Minnesota, wind chills could fall as low as 35 degrees below zero, according to The Weather Channel. By Friday, the frigid temperatures will spread through the Midwest, and highs will struggle to get above zero in eastern North Dakota, northern Wisconsin, northern Minnesota, and Michigan.
By Saturday, the cold blast will hit the Northeast, mid-Atlantic, and the Southeast. From Boston to Washington, highs will hover in the teens and 20s, said The Weather Channel.
On Sunday, a few cities may set daily record lows, including Providence, Albany, New York and Philadelphia. Boston's Logan Airport hasn't dropped below zero degrees yet this winter — but could on Sunday morning.
Snow and ice are also possible in a large swath of the country, from the Midwest and South to the Northeast, early next week. Temperatures are expected to thaw by Monday.
Despite a historic blizzard that paralyzed millions last month, this winter has been one of the warmest so far on record. New England, New York, New Jersey and Florida set their warmest November to January periods ever, according to NOAA.
