SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 AM CDT Fri Oct 09 2020 Valid 091300Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN PORTIONS OF LOUISIANA/MISSISSIPPI... ...SUMMARY... A few tornadoes are possible across southern portions of Louisiana and Mississippi today and tonight. ...Gulf Coast including southern Louisiana/southern Mississippi... Hurricane Delta, which is currently over the northwest Gulf of Mexico south of the Louisiana/Texas border, is expected to continue generally north-northeastward today and move inland across Louisiana this evening. Reference the National Hurricane Center for the latest details. Given these expectations for Delta, some possible diurnal increase/spatial expansion of Delta-peripheral convection and its gradual approach toward the coast should lead to an increase in supercell/tornado potential, particularly this afternoon through early/mid-evening. Moisture-rich mid 70s F surface dewpoints will become increasing prevalent later today inland across south-central/southeast Louisiana and far southern Mississippi in conjunction with the strongest core of low/mid-tropospheric winds on the eastern periphery of Delta. This sub-regional area is expected to have the highest probability for a few tornadoes this afternoon and evening, although a tornado risk cannot be ruled out into the overnight. Farther east, some potential for transient supercells and a brief tornado and/or convectively enhanced wind potential may exist as far east as southern Alabama and possibly the Florida Panhandle, particularly in vicinity of the warm front this afternoon through early/mid-evening. ..Guyer.. 10/09/2020
