Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CDT Sat Oct 07 2017 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL AND EASTERN GULF COASTAL AREA... ...SUMMARY... A marginal tornado threat and a few strong wind gusts will be possible on Sunday from far southeast Mississippi into south-central Alabama, the western Florida Panhandle and far western Georgia. ...Central and Eastern Gulf Coast... The National Hurricane Center is forecasting Hurricane Nate to make landfall just to the west of Mobile, AL just before daybreak on Sunday. At landfall, bands of heavy rainfall are forecast to extend northward into southern Alabama and eastward into the western Florida Panhandle. NAM forecast soundings in these areas at 15Z to 18Z on Sunday show MLCAPE in the 250 to 500 J/kg range with 0-1 km shear of 30 to 40 kt and 0-6 km shear approaching 40 kt. The strong shear environment will support a marginal tornado threat with cells that remain at least semi-discrete. A few strong wind gusts will also be possible with the stronger storms. The threat further inland into central Alabama and Georgia will depend upon how much instability develops during the day on Sunday. ..Broyles.. 10/07/2017 Read more
