🌤️ Delmarva Afternoon Update — Friday, June 12, 2026
Heat Advisory now in effect for New Castle County through 8 PM, joining Cecil County under the same alert.
What's Changed Since This Morning: NWS Mount Holly added New Castle County to the Heat Advisory this afternoon, effective until 8 PM. SPC keeps the Slight Risk for severe storms in place across the entire Delmarva, with Cape Charles, Chincoteague, Dover, Lewes, Ocean City, Salisbury, and Wilmington all in the threat area. Dangerous heat continues to drive the setup, with destabilization expected to fuel scattered late-day thunderstorms — some potentially strong to severe.
Current Severe Weather Picture: SPC maintains a Slight Risk across Delmarva for Day 1, covering both coastal and inland communities. The afternoon AFD highlights hot, humid conditions priming the atmosphere for scattered storms, with damaging wind the primary concern as cells fire late today. Day 2 currently shows no organized convective risk over the sampled points, though Sunday brings another severe chance as a cold front approaches.
Active Watches & Warnings:
- Heat Advisory — New Castle County, DE — until 8:00 PM EDT
- Heat Advisory — Cecil County, MD — until 8:00 PM EDT
Through Tonight: Expect scattered showers and thunderstorms to develop late this afternoon and into the evening across inland Delmarva, with Wilmington, Dover, Georgetown, Cambridge, and Salisbury all in line for storm chances. A cold front crosses early Saturday, ushering in drier and somewhat cooler air to start the weekend.
Bottom Line: Hot, humid, and primed for late-day storms — stay weather-aware through the evening, especially inland.
