A Week of Repeat Storms Is About to Hit the Midwest and Northeast

Thunderstorms are making an encore appearance in the Midwest and the Northeast beginning on Friday and lasting through the weekend. Here is a closer look at when and where you should expect these storms to pop up as you make your weekend plans.

Atmosphere Primed to Produce Thunderstorms Heading into the Weekend in Northern U.S.

Forecasters are warning that storms are going to erupt along the northern rim of a building heat dome along the northern Plains on Friday afternoon and evening. Friday's storms will kick off a weekend of active weather stretching from Minnesota to the east into Maryland. The stormy pattern will come on the heels of a short respite from the heat and humidity in recent days.

The greatest concentration of storms on Friday will roam the Interstate 29 and Interstate 94 corridors in the Dakotas and northern Minnesota. The forecast is calling for large hail and winds that could approach speeds of 80 mph. Motorists using these key interstates should prepare for travel disruptions due to sudden changes in visibility during times of heavy rain or hail.

Storms will ease a bit on Saturday with just spotty activity expected in a zone from Montana to South Dakota. Like Friday's storm cells, the most prominent risk will be the damaging winds and hail. A few of these rain showers and storms could creep as far east as the Great Lakes and into western Pennsylvania and the central Appalachians.

Sunday's primary action is forecast to set up over the Midwest. Wisconsin and Minnesota will be at the heart of the storm threats as the weekend comes to a close. A surge of heat and humidity building across the Midwest beginning on Sunday will serve as the fuel for this severe weather development.

In addition to the high winds and the hail, the early week storms will also pack a great deal of moisture. The heavy rain will be capable of triggering flash flooding across much of the Ohio Valley and the Northeast. The line of storms could drop as far south as West Virginia and Kentucky, a part of the nation that is already dealing with flooding issues due to this week's storm events.
