The episode as NWS PHI wrote it up.
The pressure gradient (difference) between a strong high pressure system near Nova Scotia and a developiung low pressure system along a frontal boundary near Norfolk, Virginia produced strong northeast winds overnight on the 24th along coastal Sussex County. Peak wind gusts averaged around 45 mph and coupled with heavy rain knocked over some weak tree limbs. The peak wind gust at Lewes was 47 mph. As the low pressure system moved north along the coastal waters, the pressure gradient (difference) decreased and winds became lighter toward morning on the 25th.
