Do you remember how big the flake size was at the start? It's one of the things i remember the most about that storm and read a lot of similar accounts. They were like baseball sized flakes for like the first hour (aggies sticking together). And then the CG thunder snow/sleet at sunset was unreal. A bolt struck my neighbors backyard and was incredibly loud, haven't seen anything that good. But have seen thundersnow a lot since then. Feb 03, Feb 13, Feb 17, Mar 18 also had thundersnow here.
