Chicago, Illinois – A powerful storm system sweeping across the central United States is setting up a dangerous stretch of weather from the Midwest to the East Coast, with severe thunderstorms expected to erupt tonight before an arctic blast sends temperatures plunging across the Plains and Great Lakes.
According to the National Weather Service and the Storm Prediction Center, a strengthening low pressure system over the Plains will drive a powerful cold front eastward Sunday night. That front is expected to trigger a fast-moving squall line capable of producing damaging wind gusts and severe thunderstorms across parts of the Midwest and Mid-South.
Cities including St. Louis, Chicago, Indianapolis, and Memphis could see intense storms during the evening and overnight hours as the line sweeps east. Strong winds may down trees and power lines, while brief tornadoes and heavy downpours are also possible along the leading edge of the storms.
By Monday morning, the severe weather threat is expected to shift toward the lower Great Lakes, Ohio Valley, and Tennessee Valley. The Storm Prediction Center has issued an enhanced risk for severe thunderstorms in these regions.
Farther east, conditions may become even more volatile by Monday afternoon. A developing wave of low pressure along the advancing cold front could ignite severe storms across the interior Mid-Atlantic before sunset Monday, where forecasters have outlined a moderate risk for damaging weather.
Behind the front, sharply colder air will surge southward. Wind chill values could drop into the negative teens across the northern Plains by Monday morning, with below-freezing wind chills reaching as far south as Texas.
The powerful cold front is expected to push off the East Coast by Tuesday morning, leaving much of the eastern United States with gusty winds and sharply colder temperatures. Residents across the eastern half of the country are urged to stay weather aware as conditions evolve through Monday.
