Lol...here we go again...!
Once again, this is not my “thought process”. The National Weather Service counts any & all snow that falls from October to May as the “Seasonal” total for that particular year, for example October of 2019 to May 2020.
So yes, if the miracle May snow takes place on Friday & Saturday, it will indeed count for the 19-20 “season”.
I think that it would be awesome if we got bailed out of the worst snow season on record at MDT by some historic once every hundred year May snow!
