Much to the dismay of those with holiday plans, the surge of higher humidity into the Northeast is also opening the door for heavy thunderstorms to return.
Heavy thunderstorms will ignite in the corridor from western Massachusetts to eastern Pennsylvania and far northern Virginia through Sunday evening. Residents in this same corridor are noticing a significant increase in humidity from earlier in the weekend.
A more widespread severe weather outbreak, including a few tornadoes, will commence across the North Central U.S. at the same time.
The threat for the heavy thunderstorms in the Northeast includes Pittsfield and Springfield, Massachusetts; New York City and Poughkeepsie, New York; Trenton, New Jersey, Philadelphia and Harrisburg, Pennsylvania; Baltimore and Washington, D.C.
Along the I-95 corridor, the heaviest thunderstorms will hold off until the late afternoon and evening hours.
"There will be locally severe thunderstorms with damaging winds, but heavy rain is the greater concern," stated AccuWeather.com Senior Meteorologist Frank Strait when discussing the dangers from the thunderstorms.
Worse than forcing outdoor plans indoors, the downpours may trigger flash flooding. Motorists will also face hazards from the downpours in the form of dramatically reduced visibility and an increased danger of vehicles hydroplaning at highway speeds.
Drivers planning to travel along stretches of Interstates 76, 78, 80, 84, 87, 90 and 95 should prepare for some delays and slowdowns. Airline passengers may also encounter delays.
All residents and visitors are urged to keep an eye to the sky and monitor the AccuWeather.com MinuteCast™ to stay ahead of any impending downpours as holiday picnics, parades, sporting events and other holiday festivities are being enjoyed.
Lightning strikes and localized downpours will remain concerns as a couple of showers and thunderstorms continue to create headaches for those with outdoor plans across the Northeast and mid-Atlantic through the remainder of the holiday weekend.
Remember, you are close enough to be struck by lightning if you hear thunder.
The good news is that Labor Day will not be a washout with stretches of dry weather.
