The 4-panel image below shows 1km refl (upper left), Max column hail (upper right), Hourly max wind speed (lower left), and Max hourly updraft helicity (lower right). This run of the OUNWRF (16z) shows a high concentration of training supercells over far southern parts of the FWD CWA. This can be denoted via the updraft helicity and hail fields. Values of updraft helicity exceeding 80 would suggest at least some tornado potential with these cells. We will wait and see what unfolds later today across this area.
