Strong thunderstorms to sweep from St. Louis, Chicago to Detroit into Thursday

Topic driven playlist

Thunderstorms capable of producing brief downpours and locally damaging winds will impact parts of the midwestern and northeastern United States through Thursday.

A line of storms is expected to develop from eastern Wisconsin to central Missouri during the early afternoon hours on Wednesday and track eastward into the evening.

Traverse City, Michigan; Chicago and Springfield, Illinois; and St. Louis could be hit with a strong thunderstorm during Wednesday afternoon.

By the evening hours, thunderstorms will reach Cape Girardeau, Missouri; Indianapolis and Fort Wayne, Indiana; and Lansing and Flint, Michigan.

Thunderstorms will approach Detroit by Wednesday evening but will be in a weakening stage.

The weather will clear out in time for Wednesday night baseball at Wrigley Field between the Chicago Cubs and the Los Angeles Dodgers.

While the strongest storms are expected to be few and far between, lightning from any thunderstorm could impact any outdoor activities. If you hear thunder, you are close enough to being struck by lightning.

Some small hail is also possible.

"People should be prepared for travel delays, especially where storms approach major airports during their peak intensity, during the late afternoon and evening hours," AccuWeather Senior Meteorologist Alex Sosnowski said.

Following these storms, a cold front will move across the region and lower humidity levels, but not temperatures, for Thursday.

By Thursday, thunderstorms will extend into parts of the interior Northeast. By that time, the threat for any thunderstorms producing hail or damaging winds will be low.

Brief downpours will be the main threat, which could lead to ponding on roadways and increase the risk of hydroplaning for those traveling at highway speeds. The strongest storms could be gusty.

"The showers and thunderstorms are not expected to move into the Interstate-95 corridor until Thursday night, but these storms will not produce any widespread severe weather," AccuWeather Meteorologist Brian Thompson said.

Following a dry day behind this storm, another storm will produce more widespread showers and thunderstorms from the Midwest to the Northeast this weekend. Some of these storms could be strong and produce heavy rainfall.
