A bitter Arctic blast is locked over Delmarva today, with highs only in the low to mid 20s and wind chills feeling closer to the single digits. Cold Weather Advisories remain in effect for all of Delaware and the northern Mid-Shore through 10 AM Saturday, and a rapidly strengthening offshore storm this weekend will bring strong coastal winds (gusts near/above 50 mph) plus a limited snow threat mainly toward the southern half of the peninsula.
