I wasn't here, but I'm glad it happened. I was asking for stricter guidelines for a long time. The more professional this site becomes, the better chance some institution will use us for real science.
This is an interesting chart posted from Perspecta showing record snowfall across North America in October! Also notice other years with high values. What I find strange is most high values seem to be ninos.
I'm really struggling to find analogs for a nina that had low heights over the northern plains along with above normal heights over northeast Pacific in October. Also, Europe tends to be above normal.
