SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1142 PM CST Sat Nov 08 2025 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Monday or Monday night. ...Discussion... A surface cyclone is expected to deepen as it tracks from the Long Island vicinity to the Lower St. Lawrence Valley on Monday, downstream of a highly amplified upper trough over the East. With weak mid-level lapse rates and a pronounced low-level inversion, scant elevated buoyancy may support sporadic lightning flashes within the warm conveyor. These may occur from the Cape Cod vicinity through the eastern half of ME into early evening. The trailing cold front from the aforementioned cyclone should gradually push through south FL during the morning to early afternoon. While deep convection over the peninsula appears unlikely, a couple weak thunderstorms are possible over the FL Straits and Keys vicinity. Over southern Lake MI, very cold mid-level temperatures will continue to support a snow band capable of producing sporadic lightning flashes into the afternoon. ..Grams.. 11/09/2025
