SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1145 AM CDT Thu Oct 08 2020 Valid 091200Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR SOUTHERN LOUISIANA INTO FAR SOUTHERN MISSISSIPPI... ...SUMMARY... A few tornadoes are possible mainly across parts of southern Louisiana Friday afternoon and evening. ...Central Gulf Coast... Hurricane Delta will move northward and make landfall on the southwest Louisiana coast Friday evening and move north-northeastward across central into northeast Louisiana according to the latest National Hurricane Center forecast. The gradual northward advection of a very moist/tropical airmass into southern Louisiana will occur during the day as the low-level wind field intensifies in the northeast quadrant of Hurricane Delta. Forecast soundings show mid 70s F dewpoints coincident with the development of several hundred J/kg SBCAPE with large hodographs. A few of the stronger updrafts within the outer bands of Delta may intermittently acquire low-level mesosyclones and a tornado risk. The tornado risk will slowly spread northward during the evening/overnight into southern MS, with the tornado threat diminishing with time across southern coastal parishes of Louisiana and eventually into central Louisiana during the early morning as low-level winds veer. ..Smith.. 10/08/2020
