I posted this in a thread somewhere in here a couple years ago, but can't find it, oh well here it goes again:
1. Either Jan of '67 or '68, NW corner of Athens Co, OH, we got 28" of heavy wet snow in 24hrs. When it got cold at night it froze the top 6" so hard you could walk in top of it, us kids carved out big chunks and made igloos.
2. Last week of Feb '80, again in the NW corner of Athens Co, OH, picked up 15" in five hours and it wasn't predicted (forecast was partly cloudy, chance of showers high of 38)! I got snowed in at my college studying for a test and I missed seeing as I was in my buddies dorm room, went to go home and my hand-me-down boat of a Chrysler New Yorker was a lump in the snow!
3. March '08 storm SE side of Dayton, OH, ended up with about 16" over two days.
4. Dec '04 storm, 12" in one day in Dayton no ice or sleet, 2ft of fell 1 county west of me and 31" in Liberty, IN (couple guys posted above) in that storm and 1.5" of ice 1 county SE!
5. Jan 96' tie with Jan '99, the '96 storm buried everyone in the Dayton are in all directions with a foot or more, I got about 6" IMBY for a major bust, buddy of mine's dad got 40" in Lucusville in Ross county). The '99 storm was a foot of snow with almost 2" of ice/sleet pilled on top that ruined it.
PS - The Blizzard of '78 was a miss for SE Ohio at the time, warmed up with heavy rain over night, finished with wind blown fluff after the cold wave that day (we already had about 2ft of compressed glacier on the ground at the time from dozens of snows through that winter).
