Return of Polar Vortex to Trigger Midwest Storms, Chill

Return of Polar Vortex to Trigger Midwest Storms, Chill

By Alex Sosnowski, Expert Senior Meteorologist

July 12, 2014

Rounds of thunderstorms, including severe weather, will affect the Midwest this weekend into Monday, ahead of a push of unseasonably cool air.

While the effect of the July sun and warm landscape will cancel some of the cool air, it will become surprisingly cool during what is typically the hottest time of the year.

According to AccuWeather Meteorologist Carl Erickson, “The pattern is reminiscent of a major polar plunge that occurred this past winter, which was referred to as the Polar Vortex.”

A piece of the Polar Vortex, and a summertime version at that will break off from the Arctic and drop southward this coming week.

The pattern will not bring snow or sub-zero cold but it will bring angry clouds, cool air and the risk of waterspouts over the warmer portions of Great Lakes.

The pattern will deliver multiple days with high temperatures in the lower 70s in Chicago and Detroit and even a day or two with highs in the 60s in Minneapolis and other parts of the Upper Midwest.

For fans heading to the All-Star Game at Minneapolis, the it may seem more like football weather. Jackets and long sleeves may be needed by many fans to stay comfortable.
