-- Changed Discussion --
A few changes will be made with the morning update based on the latest trends of radar and surface obs. With the northern sections having been worked over by morning rainfall, convective development over the next few hours will likely be along and south of I-40. Outflow boundaries ahead of the MCS in central KY may bring storms into northern areas again later this afternoon. Mesoanalysis shows MLCAPE values already over 2000 J/kg in southern sections, so storms will need to be monitored for severe potential, with downburst winds being the main threat. With the lack of shear and high CAPE, pulse storms may develop and peak rapidly, so those outdoors will need to pay attention and find shelter quickly.
