My area has 10-12 inches
Enid: 28-32 inches
Tulsa: 21-24 inches
Springfield, MO: 15-18 inches
In parts of Kansas, a .8 inch QPF of snow with a 50:1 ratio is 40 inches
Some of the totals could be slightly inflated from the December 19th-20th system.
50-1 is probably too high of a ratio, snow ratios don't always improve with colder Temps. The more important thing would be the depth of the Dendritic Growth Zone. 2500 feet is usually around 12-1, 5000 feet or longer and you start talking about 20-1. I'd need to see a skew-t to know.
Here you go, it's from WeatherNerds. The DGZ collapses with the arrival of snow which I find unusual compared to a very large area before it arrives.

Based off the 2nd sounding the DGZ would be between 600mb and 700mb so about 3.5k feet. Probably between 15-1 and 20-1
