Wider weather episode

The second in a series of winter storms over the course of a week developed on the 22nd over the Gulf Coast. Low pressure moved northeastward along the Eastern Seaboard, passing very near the elbow of Cape Cod by sunrise on the 23rd. The proximity of the storm track allowed some mixed precipitation to move in over parts of southern New Hampshire. Farther northwest a pivoting band of moderate to heavy snow brought double digit snowfall to much of the rest of the state. As the storm moved into the Canadian Maritimes snow quickly came to an end during the evening of the 23rd.
