Precipitation changed to plain rain in and around the local Philadelphia area during the afternoon of the 22nd, but remained intermittent light freezing rain elsewhere until the event ended during the evening of the 22nd.

The wintry mix was caused by a low pressure system that formed along the Gulf Coast States during the afternoon of the 21st. This low pressure system moved northeast and reached Mississippi on the morning of the 22nd and the Tennessee Valley during the early afternoon of the 22nd. A secondary low pressure formed along the South Carolina coast that morning and reached Cape Hatteras early that afternoon. The secondary low pressure system continued to move northeast and by 7 p.m. EST on the 22nd was located about 125 miles east of Long Beach Island, New Jersey. It passed just south of Nova Scotia overnight. The surface high pressure system that preceded the low left a cold and dry air mass in place for precipitation to start as snow. Since the high pressure system moved offshore, enough warm air in came in from the Atlantic to change the precipitation over to plain rain near Philadelphia. But, farther inland, northeast winds fed colder air into the state and prevented temperatures from rising above freezing.
