As I mentioned before, I think the CIPS web site was down for quite some time last year, but it is back. The top analogs for tomorrow night have some severe reports. This highlighted one was a worse analog. It's Mar 1, 2017, with a 1000-storm report day (Midwest sector analogs)
if you choose the southeast/south central zone in CIPS, then the computations are different, with Mar 31, 2016 being a good analog, high storm report analog day
