Severe thunderstorms with the risk of a few tornadoes will advance eastward across the northern Plains and Upper Midwest into Friday.
Cities that could experience damaging and dangerous storms include Minot, Bismarck and Fargo, N.D.; Pierre, Huron and Sioux Falls, S.D.; Omaha, Neb.; and St. Cloud, Mankato and Minneapolis, Minn.
People whether at home, at work or on the road in this area should keep an eye out for rapidly changing weather conditions.
The storms bring the full spectrum of severe weather ranging from damaging wind gusts, frequent lightning strikes, large hail and flash flooding. A few of the strongest storms can produce a tornado.
The greatest threat of severe weather will shift from central and eastern Montana and the western part of North Dakota Wednesday to the eastern part of the Dakotas, eastern Nebraska and much of Minnesota Thursday.
During Friday, the risk for severe thunderstorms will expand eastward and southwestward.
The potential for severe weather into the weekend will continue over portions of the northern Plains and will expand eastward across more of the Great Lakes.
The severe weather will be firing as a couple of storm systems move along the Canada/U.S. border, while a zone of heat builds farther south over the Rockies and Plains.
Similar setups in the past have produced one or more large, strong thunderstorm complexes, and it is likely this event will have a similar outcome, especially Thursday night into Friday. However, forecasting the exact path such complexes will take can be challenging prior to their actual formation.
Regardless of whether or not a thunderstorm complex forms, individual thunderstorms can bring isolated severe weather and lines of thunderstorms can bring damage on a more regional basis.
While many seasoned residents in the northern Plains and the Upper Midwest have experience in severe weather situations, all residents and visitors should stay on top of the weather situation over the next few days.
