Tornado, large hail risk as storms slam Eastern Seaboard
Monday, June 19, 2017, 1:08 - Strong to severe thunderstorms threaten an area spanning from portions of New England to the Northeast and Mid-Atlantic Monday. Here’s what you need to prepare for.
Risks and timing:
Strong to severe thunderstorms are forecast over parts of the Northeast into the Mid-Atlantic states this afternoon and evening. Damaging wind gusts will be the primary severe hazard but a tornado or two and some hail may also be possible.
Severe thunderstorm watches and warnings were issued Monday afternoon. For updates, see the ALERTS page of our website, here.
The greatest concentration of damaging wind is expected across the Enhanced Risk area.
“Across the surrounding Slight Risk area, weaker buoyancy across northern New England, and somewhat warmer midlevel profiles and a weaker low-level mass response across the NC/SC Piedmont will limit the severe risk in those areas,” explains the Storm Prediction Center in a statement.
There is a 2% probability of a tornado within 25 miles of the areas outlined below.

Additional unsettled conditions expected for Great Lakes/Northeast
Meanwhile, upper-level energy over parts of the Middle Mississippi Valley and over South-Central Canada will move southeastward to the Great Lakes and northeastward to the Northeast by Tuesday. The cold pool of air aloft will aid in producing showers and thunderstorms over parts of the Upper Mississippi Valley/Upper Great Lakes that will expand into parts of the Ohio Valley by Monday evening. The showers and thunderstorms will expand into the Lower Great Lakes/Northeast while extending westward to the Upper Great Lakes on Tuesday into Tuesday evening.
