Thunderstorms Ahead of Cold Front

High temperatures near 90

As a cold front moves into the Northeastern United States from the north and west on Wednesday, it will slice into humid, hot air with high temperatures near 90° and dewpoint temperatures near 70°.

The heat and humidity will result in a large amount of energy available for thunderstorm growth, and clusters of thunderstorms are likely to develop during the middle and late afternoon in Upstate New York, Northern and Western New England. By evening, these storms move through Central and some of Southern New England.

Given available energy, and a modest wind flow aloft, damaging wind gusts are possible within these storms, and the clusters of thunderstorms should organize into a squall line Wednesday evening, spanning across much of New England, New York and Pennsylvania.
