As many kick off their holiday weekend plans today, an eye will need to be kept on the sky later as a new round of powerful thunderstorms is expected across the Northeast, possibly impacting some of the big cities along I-95.
Following damage from storms late Thursday, thunderstorms will redevelop this afternoon from the central Appalachians into interior New England with a warm, humid air mass still in place.
The major cities along I-95 from Washington, D.C., to New York City could be targeted by evening, though it appears the western suburbs of each city will have the greatest risk of receiving a gusty storm.
Most of the activity will likely skirt by to the north of southern New England again today, though an isolated storm could reach Hartford, Conn., or Worcester, Mass., late in the evening.
All storms will be capable of producing frequent lightning and heavy, flooding downpours. Some locations from the central Appalachians to northern New England had up to 3 or 4 inches of rain in a few hours' time from strong storms on Thursday.
Powerful wind gusts and hail will also occur with the stronger storms, which could lead to significant damage if storms pass over populated areas.
A tornado cannot be ruled out as well, though this threat will be markedly lower compared to the past several days.
Cities at risk for severe weather this afternoon and evening include Charlottesville and Richmond, Va.; Baltimore, Md.; Allentown, Harrisburg and Philadelphia, Pa., Albany and Binghamton, N.Y., Springfield, Mass., and Concord, N.H.
Numerous interstates, sure to be busy with holiday travelers, will be impacted by the storms, including Interstates 76, 78, 80, 81, 84, 87, 88, 90, 91 and 95, among others.
Those traveling by air will want to check ahead with their airline carriers for information about flight delays. One strong thunderstorm passing over a major airport could disrupt numerous flights.
Looking deeper into the holiday weekend, the threat for a few strong storms will persist into Saturday over the Northeast, with the unsettled pattern expected to ease by Sunday.
Record-challenging heat will continue in Seattle through midweek before temperatures return to normal.
Above-normal temperatures will be the story around the Bay area to kick off the new week.
Unsettled weather in Atlanta will continue into this week, with the chance of thunderstorms remaining for the area through Tuesday.
After showers and thunderstorm come through the area on Monday, Detroit will see a period of slightly cooler temperatures for much of the week.
After the new week begins with stormy weather, the Cleveland area will see temperatures reminiscent of September move in midweek.
Dallas will see continued periods of heat and dry weather before severe storms bring cooler temperatures midweek.
