To me, snowmageddon will always be Atlanta 2014.

I imagine there is another group that would claim the 2010 blizzards in the midwest/mid-Atlantic as the, snowmageddon. However, I would argue both 2010 & 2014 as snowpocalypse--and with over 290 official (and estimated 700+) deaths the 2021 Texas storms as a better fit for snowmageddon. (not that its a competition, it was simply far more tragic)
