As a storm system slices through the Midwest, severe thunderstorms are expected from Omaha to Chicago tonight into Thursday.
A potent disturbance ejecting from the Rockies will spread rain across the Dakotas and Midwest today. Meanwhile, unusually warm air will stream northward ahead of a cold front.
These ingredients will combine to spark intense thunderstorms tonight and tomorrow. While the wet and stormy weather should stay west of Chicago through tonight, storms can arrive later tomorrow afternoon and be strong to severe.
The commute home Thursday could turn treacherous. In particular, I-90, I-94, and I-55 could have slow traffic due to torrential downpours.
Strong winds high in the atmosphere and very cold air aloft will make damaging winds and large hail the main threats, although an isolated tornado cannot be ruled out.
After sunset, the threat should transition away from severe weather as a steady rain develops through the night. Drier and breezy weather should arrive by Friday.
While heavy rain drenches the Southeast from Alabama to the Carolinas, portions of Florida will be in the path of severe thunderstorms.
Although spring may be in full swing, more than one-third of the Great Lakes remains covered in ice.
Rain will return to Atlanta Friday and Saturday as a storm system moves through to the Southeast.
More clouds will move into Cleveland to wrap up the week along with lower temperatures.
A warmup is in store for Los Angeles that will remain into the weekend and early next week.
A low pressure system has begun to spread heavy rain over parts of the Southeast, bringing the risk of flooding to the area.
