Frigid temperatures gripped much of the United States on Tuesday as 55 million people in parts of the Midwest, mid-Atlantic and Southeast remain under frost and freeze alerts.
Temperatures are set to hit 10 to 25 degrees below average, leading to chilly weather over the next few days for areas east of the Mississippi River.
The National Weather Service Weather Prediction Center said in a Monday post on X that cold weather precautions should be taken.
"Cold temperatures, near or below freezing, on Tuesday and Wednesday mornings will be felt across areas that were impacted by the recent multi-day storms," the center said.
The National Weather Service in New York cautioned that temperatures will be in the low to mid-40s on Tuesday, but the wind "will make it feel more like it’s in the 20s in the morning and 30s in the afternoon."
In Atlanta, a cooler airmass will bring cold temperatures Tuesday evening. Some areas could see freezing or near-freezing temperatures, the region's National Weather Service said in a Tuesday post on X.
A slow rebound of temperatures can be expected heading into the weekend.
Flooding also continues to be a concern Tuesday, following last week's destructive storms across the Midwest, mid-South and Northeast. At least 24 people were killed in the storms.
On Tuesday, 20 river locations remained in the major flood stage.
Louisville, Kentucky, Mayor Craig Greenberg said in a Facebook post Monday that the Ohio River had reached 35 feet in the downtown area and was projected to crest at 37 feet on Wednesday.
"This is officially one of the Top 10 flooding events in Louisville history," he wrote. "Please use caution when traveling, especially if it is along the Ohio River and be alert of road closures in your area."
Outside of river flooding, the rest of the country could see some scattered showers, thunderstorms and light snow but will have relatively low-impact weather.
Light snow will move through New England on Tuesday, while Florida can expect thunderstorms and showers. On Wednesday, there will be more showers and storms across the Northeast. The Tennessee Valley will also see some strong storms Wednesday.
