More on Mississippi Severe Threat

The threat of severe weather for portions of Mississippi is still there, but the overall tornado threat is not as impressive with latest runs.The runs below are at 21z Friday and then it really weakens on the next model runs. The tornado threat is still there(worse to the South), but the main threat looks to be strong gust winds, large hail, and torrential rainfall as the Cold front pushes thru the warm, moist, and unstable airmass that will across the state. There will be tornado warnings issued I am sure as well as FF warnings. Looks as if areas near Yazoo City, Vicksburg, and Jackson will be under the gun again this time. These areas have had there fair share of severe weather this year already. As for Alabama weather at this time it looks as if we are looking at a major flooding threat across the Tennessee Valley with 1-3" of rain possible before its over (some areas may see more.) With the snow melt from our Christmas snowstorm the ground is pretty saturated already. So if you live in or near a flood prone area please be aware of your surroundings. Stay tuned for more.
