Severe storms to unleash damaging winds across northeastern U.S. into Tuesday night
An unusually strong push of dry, Canadian air will clash with high heat and humidity from the Mississippi Valley through the Ohio Valley, mid-Atlantic and into western New England.
Thunderstorms will congregate and gain strength along this dividing line on Tuesday afternoon and evening, stretching from Paducah, Kentucky, to Pittsburgh and Syracuse, New York.
Blinding downpours and winds high enough to knock down trees and power lines and toss around loose items will be the most far-reaching impact. Hail can also occur.
“A few of the strongest storms could even spin up a tornado,” AccuWeather Meteorologist Eric Leister said.
The thunderstorms will tend to move fast enough to limit the flash flood threat to localized areas. Ponding of water on roads and slight rises on small streams will be more common.
Stretches of interstates 64 70, 80, 81 87 and 90, may be slowed during busy commute times as downpours reduce visibility to near zero.
Those headed to Little League World Series games in Williamsport, Pennsylvania, should come prepared for stormy conditions and delays. Fans may need to evacuate the stands if lightning is nearby. ■
