CUmet Posted April 15, 2011 Share Posted April 15, 2011 The cell currently south of Brandon, MS and the one to the southwest are in a really good environment, and will continue to be so for quite some time. There is uninterrupted inflow from the south, with strong diabatic heating from all the clear sky to its east. Also, although the LLJ has been shifting eastward with time, it should slow its eastward progression substantially over the next few hours. This should continue to provide a low-level shear environment favorable for significant tornadoes. These cells are likely to be the main show over the next 3 hours or so as they head into east-central MS and west-central AL. Link to comment Share on other sites More sharing options...
