The threat for severe thunderstorms will shift from the Great Lakes to the northeastern United States early in the week.
A front colliding with hot and humid conditions will provide an ideal environment for dangerous storms to develop across the region through Monday.
On the heels of severe weather in the northern Plains on Saturday, violent storms will target the Great Lakes into Sunday night.
Des Moines, Iowa; Chicago; Milwaukee and Madison, Wisconsin; could be at risk for locally damaging winds, hail and torrential downpours on Sunday.
While likely in a weakening stage, storms could remain quite gusty by the time they reach Detroit; Fort Wayne, Indiana; and Toledo and Cleveland, Ohio, on Sunday night into Monday morning.
With plenty of moisture in place, storms could dump enough rain in a short amount of time to cause flash and urban flooding.
As the front shifts eastward on Monday, so will the threat for severe weather.
"Those from the Ohio River Valley to the interior Northeast will have the potential for a few severe storms to roll through Monday afternoon," according to AccuWeather Meteorologist Brett Rathbun.
Areas from Albany, New York, southwestward to Pittsburgh and Indianapolis could face a violent storm or two to start the workweek.
"Damaging winds and flash flooding will be the main threats, though a few places could see some small hail," he stated. "Sporadic power outages will be possible."
While not every location within the threat zone will experience severe weather, residents should remain vigilant to local weather bulletins throughout the day.
Locations where showers and storms move through during the first half of the day are most likely to be spared by severe weather during the afternoon hours.
Areas along the I-95 corridor will likely stay dry for most of Monday.
"By Monday evening, these storms will be in a weakening stage as they approach Washington, D.C., to New York City and Boston," Rathbun explained, "however, a few storms could still be locally heavy and gusty."
Those tired of the heat and humidity out ahead of the storms will be pleasantly surprised following the front.
"The passage of the heavy storms will open the door for less humid air to pour into the Midwest and Northeast," according to AccuWeather Senior Meteorologist Kristina Pydynowski.
"However, heat and humidity will quickly return to the Upper Midwest by midweek and then the Northeast toward the new weekend."
