Severe Thunderstorms Shift From Plains to Midwest

Strong and severe thunderstorms from Canada and the northern Plains Thursday will shift into the Midwest and Ohio Valley in time for the weekend.

The same system in southern Canada that is bringing strong to severe thunderstorms across Alberta and Saskatchewan will extend farther south Thursday into the northern Plains.

After some gusty storms moved through North Dakota Thursday morning, thunderstorms are expected to re-fire this afternoon. These storms will include the cities of Minot, Grand Forks and Fargo in North Dakota, but into Aberdeen, South Dakota.

Storms farther north towards the low in Canada could produce tornadoes this afternoon and evening. However, across the United States, the greatest risks with the afternoon storms are damaging wind gusts in excess of 70 mph as well as torrential downpours.

For the afternoon and into the evening, these storms will shift to southern Minnesota and northern Iowa, bringing torrential rains and gusty winds. Cities that are likely to see these strong to severe storms include Sioux Falls, South Dakota, the suburbs south and west of Saint Cloud and Minneapolis, Minnesota, into Mason City and Waterloo, Iowa.

Through the end of the week, the center of the storm will head towards the Great Lakes. On Friday, thunderstorms will stretch from Minnesota, Iowa and Wisconsin to Indianapolis by the end of the day. For the most part, these storms are not likely to be severe, but they could contain some locally strong wind gusts, especially around the Chicago area Friday night.

The system does, however, look to regroup late Saturday as the low from Canada dives into the northern Great Lakes.

Thunderstorms during the daylight hours on Saturday will be typical summertime storms. However, as the sun sets on Saturday, strong to severe storms will erupt.

Saturday night and through Sunday, thunderstorms right along the jet stream will be firing and could potentially be severe. From Illinois and Indiana into Michigan and the Ohio Valley could contain heavy rain and potentially some gusty winds for second half of the weekend.
