Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0638 PM CST Wed Nov 26 2025 Valid 270100Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms appears negligible across much of the nation tonight. ...01Z Update... ...Southern Florida/Keys... Convection in a small cluster initially centered over interior southern Florida, generally to the northwest of Greater Miami, has undergone recent weakening. While occasional lightning persists in stronger cores, guidance suggests that potential for this continuing inland and near coastal areas will become increasingly negligible through 02-03Z. Otherwise, although more uncertain due to model spread, potential for scattered convection capable of producing lightning might increase late tonight near the lower Keys, if an increase in large-scale ascent is able to overcome inhibition associated with relatively warm layers aloft. ..Kerr.. 11/27/2025Read more
