Delmarva is settling into a prolonged, dangerous stretch of cold through the end of the week, with daytime highs stuck in the 20s and overnight lows dropping into the single digits—creating wind chills below zero at times. Friday could challenge a record for the coldest high temperature. Attention then turns to a rapidly strengthening coastal storm this weekend that could bring snow, high winds, and coastal flooding, though the exact track (and impacts) remain uncertain.

A rare and potentially record-setting blast of Arctic air settles over Delmarva, bringing highs stuck in the 20s and low 30s but feeling much colder due to wind chills. By midweek into Friday night, overnight lows drop to the single digits, with wind chills well below zero—cold enough for frostbite and hypothermia within minutes. We are also watching a potential coastal storm late Saturday into Sunday that could bring snow, strong winds, and coastal flooding/erosion concerns.
