What happened

The episode as NWS PHI wrote it up.

A weak low pressure system dropped a wintry mix of precipitation across Cecil, Kent and Queen Anne's counties in Maryland. Snowfall averaged 1 to 2 inches with ice accretions less than one tenth of an inch. Precipitation began during the early morning on the 31st as snow in Cecil and Kent Counties and a wintry mix across Queen Anne's County. The snow changed to a wintry mix before it ended in Cecil County and plain rain before it ended elsewhere. All precipitation ended by Noon EST. The precipitation's timing coupled with high traffic volume resulted in numerous accidents.

Specific snowfall included 1.0 inch in Millington (Kent County). The low pressure system that caused the wintry mix moved northeast from Mobile, Alabama at 7 a.m. EST on the 31st and reached Wilmington, North Carolina at 1 p.m. EST and was southeast of Long Island at 7 p.m. EST that evening.
