Under mostly sunny skies this afternoon, temperatures are surging with inland spots reaching the mid and even upper 70s.

Watch for areas of fog early Sunday, then much warmer, with 70s later in the day.

Delmarva stays sunny but cold today, then turns cloudier Friday ahead of a clipper and an arctic front. Snow looks minimal (if any, just a dusting), but a sharp temperature crash and powerful winds arrive Saturday—bringing dangerous wind chills into the single digits and potentially below zero.

A cooler and wetter start to the week for Delmarva, then warming temperatures midweek. Hurricane Erin will remain offshore, but trigger building swells and rip current risk by early Wednesday.
