What happened

The episode as NWS PHI wrote it up.

A weak low pressure system developed from an inverted trough off the south Atlantic Coast the morning of the 12th. As the low moved off the North Carolina coast during the evening of the 12th, moisture spilled north into the Maryland Eastern Shore. A high pressure system nestled over New England left some relatively cold air near the surface. While it was warm enough aloft for precipitation to fall as rain, near the ground temperatures were around or below the freezing mark. A few hours of light sleet and/or freezing rain occurred across northern parts of the Maryland Eastern Shore. Water equivalents were generally under one tenth of an inch. Untreated roadways and walkways were hazardous.
