Picked around 1.4" last night.
Great analysis OHWeather. It will be interesting to see how everything works out. As you mentioned, dry arctic air is never a good thing for seeing significant totals. Seems that you can get away with lackluster parameters when lake temps are warmer, but now that the lake has cooled, everything needs to come together perfectly to see high totals.
Looking at the bufkit text output, both the GFS and NAM have winds coming around to 320 for about 9-12 hours starting tomorrow. The 320 fetch provides about 54 miles of open water in NE OH... less than optimal for heavy snows.
With lake effect there are always some surprises so we'll see what happens. CLE seems to have exanded snowfall totals in their latest map. I'd be disappointed and surprised not to see 8"-10" IMBY.
