Rounds of Thunderstorms to Spoil Weekend Plans for Midwest, Northeast

Rounds of thunderstorms, some locally severe, will quickly roll from the Midwest to the Northeast into next week.

Several rounds of storms will travel hundreds of miles eastward on the northern edge of a large area of sweltering heat anchored in the Southern states.

The bulk of the storms will neither be as severe, nor as widespread as that of July 12-13. However, there will be some exceptions, such as the small outbreak of tornadoes that occurred in Illinois on Thursday, July 16, 2015.

Enough heat will build into the northern tier states this weekend to give the storms a boost.

People spending time outdoors, participating in activities such as fishing, golfing, swimming or a ballgame should keep alert for rapidly changing weather conditions, due to the rather fast movement of some of the storms.

What could start off as a sunny and summery day could quickly turn stormy. Stay alert to rapidly changing conditions by using MinuteCast® if you are headed outdoors.

Due to the fast flow of air, some of the storms can survive for an extended period of time. Rather than occurring during the typical prime time, during the afternoon and early evening, a few can occur during the overnight and morning hours.

The unstable atmosphere could produce more than one storm per day.

Some communities could be hit with flash flooding, in addition to frequent lightning strikes and strong wind gusts. A couple of tornadoes could be produced during the strongest storms.

This potential outbreak of severe weather will occur along an advancing front, will reach the Ohio Valley Sunday night and then the Northeast on Monday into Monday night.

Behind that early week batch of storms, another break of less humid and somewhat cooler conditions will shift eastward for a brief visit.
