Strong to Severe Thunderstorms Possible Across the Northeast on Tuesday
As a warm front moves northward across the Northeast during the morning hours on Tuesday, warm moist air will track northward ahead of an area of low pressure. Instability will build ahead of the low as daytime heating increases. Given this forcing and instability, showers and thunderstorms are forecast along and ahead of a cold front, with a few storms becoming severe. Hail and damaging winds will be the primary hazards with the stronger storms. Morning shower and thunderstorm activity may decrease the severe risk later in the day.

Ongoing shower and thunderstorm activity just ahead of a cold front will track toward the coast throughout the day. With warm air ahead of the front some instability could build ahead of the front, some modest instability could build across the region on Tuesday.
