A significant nor'easter is set to impact the northeastern United States, potentially delivering heavy snow and powerful winds. The storm is anticipated to develop near the Mid-Atlantic coast on Sunday, with effects spanning from Washington, D.C., to Boston, particularly affecting southern New England. The storm is expected to undergo bombogenesis, a rapid intensification process where the storm's central pressure drops dramatically within 24 hours. This could result in heavier snowfall than initially predicted, especially in areas like Cape Cod, where models suggest a high probability of exceeding 12 inches of snow.
