A more active severe weather pattern is getting underway in the Midwest and Plains, which could produce large hail, wind damage and a strong tornado threat into early next week.
A multiday siege of severe weather will first strike the Great Lakes and Midwest through the end of this week before shifting to the Great Plains over the weekend and into early next week.
Tornadoes – some possibly strong – damaging hail and destructive straight-line winds are all potential threats in what could be multiple outbreaks of severe thunderstorms through Tuesday.
The Latest
The map below shows the latest radar, watches and warnings issued by NOAA's Storm Prediction Center and the National Weather Service.
There have already been at least a couple of confirmed tornadoes Thursday, including in Swift County, Minnesota, where a barn and part of a home were destroyed, and near New Richmond, Wisconsin. Reports of a rotating wall cloud, sometimes the precursor of a tornado, prompted a tornado warning earlier this afternoon for downtown Minneapolis and some of the city's northern suburbs, where pea-size hail was reported in the far northwest suburb of Rogers.
Late Week Forecast
-Through Thursday Night: Areas shaded in red below from east-central Minnesota to much of Wisconsin, northeast Illinois, northern Indiana, western Michigan and northwest Ohio have the greatest chance to see severe weather, including Chicago and Milwaukee. Areas on the eastern edge of the red area in Michigan, northern Indiana and northwest Ohio will have their peak severe threat tonight.
Hail the size of golf balls or larger, damaging straight-line winds and a few tornadoes, possibly strong (EF2 or greater damage), are possible in this area.
The chance of severe weather will be more isolated in areas farther south toward the Ohio Valley, as shaded in orange. But, any severe storms that form in this area could pack high winds, damaging hail and a tornado threat.
Isolated severe storms could also extend as far east as the mid-Atlantic.
-Friday-Friday Night: An outbreak of severe storms is possible in the Ohio and mid-Mississippi valleys, as shaded in the red areas below. That includes Cincinnati, Indianapolis, Louisville, Kentucky, Nashville and St. Louis.
Damaging hail larger than the size of golf balls, high winds gusting over 75 mph and tornadoes are all potential threats. Some tornadoes could be strong.
Widespread damaging winds capable of downing many trees and knocking out power will be a particular concern from southeast Missouri to southern Illinois, southern Indiana and western and central Kentucky.
Other more isolated severe storms could extend as far southwest as the Ark-La-Tex, and as far east as the mid-Atlantic states.
Weekend-Early Next Week Forecast
-Saturday: Scattered severe storms could impact parts of the East, from New York state to North Carolina, as well as parts of the South, particularly Texas, Oklahoma and Arkansas.
-Sunday-Monday: The biggest threat of severe storms will shift into the Central and Southern Plains, particularly from Kansas into Oklahoma and northern Texas. While it's too early for specifics, the storms could bring a significant threat of tornadoes, some possibly strong, as well as wind damage and large hail.
Dallas-Fort Worth, Oklahoma City, Tulsa, Oklahoma, and Wichita, Kansas, are a few of the cities that should keep a close eye on the forecast for Sunday and Monday.
-Tuesday: Severe weather may shift farther east toward the Ark-La-Tex and mid-Mississippi Valley.
There is a potential for an outbreak of severe thunderstorms on one or more of those days from Sunday through Tuesday.

A More Favorable Pattern For Severe Weather
A southward plunge of the jet stream will carve into the central states by Friday, which will introduce strong winds aloft across the Plains and Midwest.
In this pattern, warm and humid air streams north from the Gulf into the Plains and Midwest under that active jet stream.
It's a setup more favorable for severe thunderstorms this time of year in the Plains and Midwest, which are the regions where tornadoes are most common in May.
