Severe weather will push eastward across the Midwest and into part of the Northeast in the upcoming week.
"We are fairly confident there will be a severe weather outbreak in the Midwest Monday into Tuesday," AccuWeather Severe Weather Expert Henry Margusity said.
"The combination of warmth, high humidity and a strong jet stream could create an elevated risk of storms with damaging wind gusts and a few tornadoes."
The storms will sweep through and impact cities from Chicago, Milwaukee and St. Louis Monday and Monday night then will move into Cleveland, Cincinnati and Pittsburgh on Tuesday.
Anyone traveling or staying home during the first part of the Independence Day week will need to keep an eye on the weather situation, as the storms could have damaging and life-threatening consequences.
In addition to the risk of frequent lightning strikes, thunderstorms with the forecasted severe weather outbreak next week will be strong enough in some areas to down trees, cut power and cause property damage. Travel delays are likely on the roads and possibly at major airport hubs as the storms move through.
"The severity of the storms by the time they reach the I-95 corridor at midweek is uncertain at this point," Margusity said.
Warm and very humid conditions will build over the Ohio Valley, Great Lakes and Northeast during the first part of the week, ahead of much cooler air.
While the heat will not set any records, the combination of warmth and high humidity will send AccuWeather RealFeel® temperatures well into the 90s and even to the century mark. The conditions could pose issues for those with respiratory problems or in ill health.
However, the changeable weather pattern will continue. Much cooler air will then push first across the Great Lakes at midweek and then into the Northeast toward the end of the week.
"There may be two pushes of cool air that occur, and each could be preceded by a round of thunderstorms," AccuWeather Senior Meteorologist John Gresiak said. "Enough energy could remain with the system to bring severe weather to the coastal Northeast."
How cool it becomes will depend on the amount of sunshine.
Some areas around the Great Lakes and northern Appalachians, that manage to hold onto clouds in the wake of the storms, could have highs in the 60s for a day or two.
Looking ahead to Independence Day, the early indications are that the storms will have cleared the Northeast coast by the evening so that most areas from Chicago to Washington, D.C., New York City and Boston are free of rain for festivities, including fireworks.
Meanwhile, people along the southern Atlantic coast will need to keep an eye on the nearby Atlantic for possible tropical development.
