🌤️ Delmarva Afternoon Update — Tuesday, July 14, 2026
Heads up: NWS just issued a wave of Heat Advisories across Delmarva plus an Extreme Heat Warning for New Castle County — all taking effect Wednesday.
What's Changed Since This Morning: The big afternoon development is the heat messaging. NWS Mount Holly, Wakefield, and Baltimore/Washington all rolled out heat headlines for tomorrow between roughly 10–11 AM and 8 PM, with New Castle County escalated to an Extreme Heat Warning. SPC also nudged Day 2 to a General Thunderstorms Risk over northern Delmarva including Dover and Wilmington. Today itself hasn't changed much — sun continues to dominate.
Current Severe Weather Picture: SPC has no organized severe risk over Delmarva for Day 1. For Day 2 (Wednesday), a General Thunderstorms Risk is drawn over the northern zones including Dover and Wilmington — non-severe thunder potential, not a categorical severe outlook. The bigger short-term hazard is heat, not storms. AFD guidance flags the weekend as the next unsettled window, when some storms could turn severe with heavy rainfall.

PoPs are 0% across all sampled points — dry overnight with light southwest winds and warm, muggy conditions building ahead of tomorrow's peak heat.
Bottom Line: Enjoy tonight's calm sun — Wednesday's the dangerous day, with Extreme Heat in New Castle and Heat Advisories blanketing most of Delmarva.
