Severe Storms to Cross Midwest Sunday to Monday

The stage is set for severe thunderstorms to erupt and threaten a large part of the Midwest later Sunday through Monday.

The severe weather spanning the end of the weekend and the first part of the new week will follow the violent thunderstorms closing out Saturday around central Illinois and North Dakota.

Building heat will then fuel a new round of severe thunderstorms around Minnesota Sunday afternoon.

"Initially, the severe storms late Sunday afternoon will remain discrete with the threat for hail, damaging winds and isolated tornadoes on the table," stated AccuWeather Meteorologist Becky Elliott.

Fargo, North Dakota, and St. Cloud and Minneapolis, Minnesota, will be the first targets of the severe weather later Sunday.

The violent thunderstorms will then track southward Sunday night, but will not diminish overnight.

"As the sun goes down, energy known as the low-level jet will increase, and this will act to fuel storms even more," added Elliott.

"Thunderstorms will merge into a large squall line over southern Minnesota, northern Iowa and Wisconsin Sunday night," continued Elliott. "This line of storms will race southeast into the early morning hours of Monday and has the potential to produce damaging wind gusts during its life span."

It is possible that the thunderstorms could evolve into a dangerous and long-lasting derecho.

Rochester, Minnesota; Cedar Rapids, Iowa; La Crosse and Madison, Wisconsin; and Rockford, Illinois, are at risk of the severe weather Sunday night.

The violent thunderstorms will take aim at Chicago late Sunday night into the first part of Monday, potentially leading to a slow morning commute and a nightmare for air travelers due to the ripple effect of flight delays.

The severe thunderstorms will then drop southward to the Ohio River on Monday, taking aim at the cities of Springfield, Illinois; Indianapolis, Indiana; and Louisville and Cincinnati, Ohio, with damaging winds and flooding downpours. The threat may also expand eastward to Columbus, Ohio.
