3. Nor'easter Today

Nor'easters thrive on the extreme temperature contrast between two air masses.

This temperature gradient creates instability, fueling a low-pressure center that intensifies as it moves toward New England and the Canadian Maritimes. 3. Nor'easter

A is a powerful macro-scale extratropical cyclone that tracks along the East Coast of North America. It is defined by its strong winds blowing from the northeast, which result from a low-pressure system moving northward along the coast. While they can occur year-round, these storms are most frequent and intense between September and April, often bringing heavy snow, torrential rain, and hurricane-force winds to the heavily populated I-95 corridor.
