From Fox Weather:
A rare severe weather threat is targeting nearly 2 million people across northern New England and New York‘s North Country beginning Tuesday afternoon, with thunderstorms capable of producing hurricane-force wind gusts and even tornadoes in a region that rarely experiences intense severe weather.
Storms will be fueled by a heat dome baking much of the Northeast, with temperatures in the upper 90s and places like Plattsburgh and Syracuse, New York, expected to approach near-record highs. A powerful storm system moving out of Canada will collide with this hot, humid air, triggering thunderstorms beginning Tuesday afternoon. The greatest risk of the strongest storms will be across parts of northern Maine, northern New Hampshire, northern Vermont and New York’s North Country.
