Daily barrages of intense storms threaten flooding, damage in the Northeast … again

Another stormy stretch is underway in the Northeast, renewing flooding and storm damage concerns for a region that’s endured several bouts in recent weeks. ⛈️ Get your local forecast in the CNN Weather app ☔️ Repetitive rounds of rain and storms with little reprieve between them each day began on Sunday and will continue through at least Thursday. A heat dome is partially responsible: It’s steering the jet stream — the river of air storms flow through — into the region as it bakes areas farther south with record-challenging heat. It’s not just rain that’s concerning for the Northeast. Severe thunderstorms are expected Tuesday through Thursday that could deliver damaging wind gusts, hail and even a few tornadoes. Here’s what to expect each day. Tuesday’s forecast A few rounds of scattered severe thunderstorms are possible Tuesday. Showers and thunderstorms moved through parts of New England, New York, New Jersey and Pennsylvania in the morning. These storms weren’t severe, but some will continue into the afternoon and could cause isolated flooding issues. A new round of severe thunderstorms is possible starting late in the afternoon or early in the evening around southern New York. These storms will likely push south and east into Tuesday night. Damaging wind gusts are the main threat with any severe thunderstorms, but some hail and a couple of tornadoes are also possible. Any storm, severe or not, could also deliver heavy rain. Flooding issues should be isolated, but any area caught under multiple storms is at the greatest risk for street flooding or rises on smaller waterways. Wednesday’s forecast The forecast is basically a rinse and repeat of Tuesday’s, but the afternoon severe thunderstorm threat is shaping up to be a bit more concerning. Strong to severe thunderstorms are possible in the morning, especially near the eastern Great Lakes. These early storms will eventually diminish and give the atmosphere enough time to recharge for another round starting in the afternoon. Storms may still be scattered, but there could also be a few supercell thunderstorms. Supercells are more likely to bring stronger winds, drop larger hail and produce longer-lived tornadoes than other types of storms. Some non-supercell storms could also congeal into more organized lines of storms that would increase the threat of wind damage. Wednesday’s flood threat is also higher than Tuesday’s because the storms could be stronger and move over the same areas rained on in previous days. Thursday’s forecast Rain and storm threats will start to shift away from the Northeast on Thursday, but isolated flooding issues are still possible in much of southern New England and parts of eastern New York — including New York City — New Jersey and Pennsylvania. Stronger storms with damaging winds and hail will focus mainly on the Mid-Atlantic, including Washington, DC. Parts of southern Pennsylvania and southern New Jersey could still get clipped by these storms. The best chance for these damaging storms is from later in the afternoon into Thursday night. The Northeast will mostly dry out on Friday and remain that way through the weekend.
