What happened
The episode as NWS PHI wrote it up.
A very cold and dry air mass built into the Delmarva Peninsula on the 1st and the 2nd. As the high pressure system built into New England and the adjacent coastal waters, the circulation around it and a low pressure system over the Lower Ohio Valley started to bring in warmer air from the Atlantic Ocean. In spite of this, the air was cold enough at the start for precipitation to begin as light freezing rain and sleet during the evening of the 2nd. The change to plain rain occurred quickly in Kent County and took longer in New Castle County (until around 4 a.m. EST on the 3rd). Even there, the ice accretion was generally less than one tenth of an inch. Because this occurred late on a weekend night, the number of reported accidents was not very high.
