☀️ Delmarva Weather Update — Tuesday, July 14, 2026
Heat Advisories and an Extreme Heat Warning for New Castle County kick in Wednesday morning — details below.
Today's Weather Story: Full sunshine rules Delmarva today under a building ridge, with a light southwest breeze nudging inland highs into the low 90s. The coast stays noticeably cooler thanks to an onshore component near the beaches and barrier islands. It's a dry, quiet day — the calm before a serious heat spike Wednesday.
Across Delmarva:
- Wilmington, DE: Sunny, high 93°F, SW 5–10 mph
- Dover, DE: Sunny, high 92°F, SW 5–10 mph
- Georgetown, DE: Sunny, high 91°F, SW 0–10 mph

Active Weather Alerts:
- Extreme Heat Warning — New Castle County, 10 AM–8 PM Wednesday
- Heat Advisory — Delaware Beaches, 10 AM–8 PM Wednesday
- Heat Advisory — Kent & Inland Sussex (DE), Caroline (MD), 10 AM–8 PM Wednesday
- Heat Advisory — Kent, Queen Anne's, Talbot (MD), 10 AM–8 PM Wednesday
Severe Weather Outlook: SPC has no severe risk over Delmarva today — expect a completely quiet convective picture. By Wednesday, a General Thunderstorms area brushes northern Delaware including Wilmington and Dover, but that's a low-end signal, not a severe risk. WPC shows no Delmarva-specific excessive rainfall concern; any heavier rain and flash flooding potential holds off until the weekend when a front and upper disturbance arrive.
Why This Setup: An upper ridge is building overhead while a stalled boundary keeps organized storms well away, allowing sunshine and southwest flow to pump warm, increasingly humid air into the region. That same flow is what loads the dice for Wednesday's dangerous heat.
Looking Ahead: Wednesday is the peak — heat index values climb into advisory and warning territory, especially around Wilmington. Thursday and Friday stay hot but a touch less extreme before storm chances ramp up this weekend.
Bottom Line: Enjoy a bright, breezy 80s-to-low-90s day, then prep now for a dangerously hot Wednesday — hydrate early and check on neighbors.
