Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1236 AM CDT Thu Oct 08 2020 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF SOUTHERN LOUISIANA AND FAR SOUTHERN MISSISSIPPI... ...SUMMARY... A tornado is possible over southern Louisiana or far southern Mississippi late tonight. ...Southern Louisiana/Far Southern Mississippi... The National Hurricane Center is forecasting Hurricane Delta to become a major hurricane by this evening as it tracks into the northwest Gulf of Mexico. The outer bands of Hurricane Delta will likely overspread southern Louisiana late tonight. Forecast soundings near Baton Rouge from 06Z to 12Z early on Friday increase 0-1 km shear from 25 to 35 kt. This will be coincident with veering winds with height and 40 to 50 kt of low-level flow. The wind profile will be favorable for storm rotation with discrete cells that move inland. The stronger rotating storms will have an isolated tornado threat. As a result, a tornado could occur from south-central Louisiana east-northeastward into far southern Mississippi late tonight. ..Broyles/Squitieri.. 10/08/2020
