More than 60 million people face disruptive storms across the eastern United States into Wednesday night with property damage and power outages possible in some of the region’s largest cities.
Areas from North Carolina through Maine are at risk of thunderstorms, but the strongest of the bunch are forecast to focus on a zone from central Virginia into Connecticut.
The storms developed at an inopportune time for motorists traveling during their evening commutes.
“The late-day commute in Washington, D.C., Baltimore, Philadelphia, New York City and Boston is likely to be a mess,” AccuWeather Senior Meteorologist Alex Sosnowski said.
“Major highways that will be in the path of the storms include Interstates 64, 66, 70, 76, 78, 80, 81, 84, 86, 87, 88, 91 and 93,” Sosnowski added. Folks headed to airports across the region may also encounter delays or cancellations due to the stormy weather.

Although a major severe thunderstorm outbreak is not expected, all modes of severe weather are possible, including winds over 60 mph, hail, flooding downpours and frequent lightning.
A few isolated tornadoes cannot be ruled out.
People across the region should remain alert for severe weather into Thursday as a cold front moving in from the Midwest sets off another round of storms.

Thursday's storms are expected to erupt farther west than those at midweek, focusing on an area from central Ohio into northern Maine, and even parts of eastern Ontario and southern Quebec.
