Here is a look at the vLAPS forecast at 20Z, valid at 2215Z.  The forecast is a 2 hour and 15 minute forecast.

Here is the observed reflectivity data overlaid on top of the model forecast.  The model is doing pretty well!  It has pretty good placement of the storm cluster, and it hints at supercellular storm modes, which is what is currently being observed.  Helicity was not available at this time.
