Severe weather to threaten parts of northeastern US Tuesday as stormy pattern resumes

Dangerous storms, including the potential for isolated tornadoes, will sweep from the Ohio Valley to the mid-Atlantic on Tuesday.
The dry break on Memorial Day has come to an end, with rounds of showers and thunderstorms returning to the region into midweek.
Leftover rain from the thunderstorms that unleashed destructive tornadoes in Ohio on Monday night will spread through the mid-Atlantic on Tuesday morning.
Sunshine can break out behind this initial batch of rain, which will help to boost temperatures and spark a new round of severe thunderstorms during Tuesday afternoon.
AccuWeather meteorologists are concerned that these storms will produce damaging winds, hail, torrential downpours and even some tornadoes from northern and central Ohio through Pennsylvania, northern and central Maryland and New Jersey.
Drivers in this zone should be prepared to face sudden reductions in visibility, and anyone outdoors when the storms threaten should seek shelter inside immediately. As soon as the first rumble of thunder is heard, the risk of being struck by lightning is present.

The storms will fuel off of hot and humid air across the Ohio Valley and mid-Atlantic, with high temperatures around 90 degrees Fahrenheit expected from Columbus, Ohio, to Washington, D.C., and Baltimore.
Areas farther north will be kept cooler by plenty of clouds and soaking rain.
Highs may only be held in the upper 50s to lower 60s F from Hartford, Connecticut; to Burlington, Vermont; Boston; and Portland, Maine.
Bangor, Maine, may be on the northern fringe of Tuesday's rain.

Those with sporting events, construction or landscape projects or field work will be disappointed to hear that there may be more showers and storms rolling through the Northeast on Wednesday and again on Thursday.
There can be the risk of severe storms yet again on both of these days.
A persistent front draped over the region will be the culprit for the stormy pattern.
High temperatures will be up and down this week from the Ohio Valley to the mid-Atlantic and Northeast due to this shifty front, according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.
As the position of the front wobbles around, temperatures can fluctuate 10-15 degrees from one day to the next in some areas.
"North of the front, conditions will be on the cooler side, especially in areas of cloud cover," Pastelok said. "South of the front, temperatures well above normal along with higher humidity."
If the front shifts far enough north, Thursday has the potential to be the hottest day yet this season from Washington, D.C., to Philadelphia.
