What happened

The episode as NWS PHI wrote it up.

Two bands of light snow, one with a low pressure system's warm front and the second with its cold front moved through Delaware during the late morning and the afternoon of the 5th. Accumulations in New Castle County averaged two inches and were around an inch or less elsewhere in the state. High temperatures in Kent and New Castle Counties were generally below freezing. The light snow caused slippery travel conditions on untreated roadways.
