A late season, but significant severe weather outbreak is becoming increasingly likely tomorrow across portions of the Mississippi/Tennessee River Valleys. Starting this evening, a powerful squall line will develop in Western Oklahoma and begin to move east overnight. As it does, increasing moisture and instability will develop ahead of the line, allowing for the severe weather threat to grow overnight. Very impressive wind speeds above the ground will allow for damaging wind gusts with this line. In addition, strong low level shear also raises the possibility of tornadoes, some of which could be strong, especially tomorrow afternoon across the areas outlined below.
As we often do in significant severe weather events, we have our high resolution model ready to go. This model will be floating over the areas of greatest concern and will be forecasting the potential of severe weather in high detail.
