SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0723 PM CDT Thu Oct 30 2025 Valid 310100Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across the northern Middle Atlantic tonight. ...01z Update... Upper low is currently lifting north-northeast across western PA as strong midlevel jet translates toward southern New England. Exit region of this feature will encourage weak elevated convection across the northern Middle Atlantic, primarily this evening, where weak buoyancy appears adequate for a few flashes of lightning within the deepest updrafts. 00z analysis supports this with a narrow corridor of 250-500 J/kg MUCAPE extending across NJ. While weak elevated convection may develop farther north into portions of VT/NH, instability will likely prove too meager to warrant 10% thunder probabilities. ..Darrow.. 10/31/2025
