It will be a stormy start to the weekend from Nebraska to Michigan as severe storms fire again along the northern periphery of a surge of heat in the Plains.
While some of these storms across South Dakota and Minnesota will continue from Friday night through the morning hours, a majority of the storms across the region will not develop until the afternoon.
Once initiated, these storms will come together to form complexes that will persist through Saturday night.
As these storms develop and intensify, they will be capable of producing blinding downpours, hail as large as baseballs and damaging wind gusts up to 70 mph. Although they will not be widespread, a few stronger storms from Western Nebraska through southern Minnesota may produce a tornado during the afternoon and evening.
Flash flooding will also be an issue with the slower moving thunderstorms as they could easily drop significant rainfall over a short period of time.
Saturday's severe weather will be caused by the same slow-moving system that produced severe weather across a similar area on Friday.
Major cities in the path of severe weather for a second day in a row include Fargo, N.D., Rapid City and Sioux Falls, S.D., Minneapolis, Minn., and Madison, Wis.
In addition to the major cities at risk for severe weather, several sporting events may be impacted as well.
Two major sporting events that could be affected by these storms include the Atlanta Braves playing against the Milwaukee Brewers in Milwaukee, Wis., at 4:10 p.m. EDT and the NASCAR Nationwide race at Road America in Elkhart Lake, Wis., at 5 p.m. EDT.
Fortunately, the forecast looks dry for the College World Series in Omaha, Neb.
The threat of severe thunderstorms will continue into Sunday across the Plains as the same slow-moving storm system tracks towards Ontario.
