When I looked up at the mountain around 11:00 am the cloud layer was about 7,000 feet and above, and there was no snow below that level. When I left work this evening, it was starting to get dark but from what I could tell, there was no snow below 10,000 feet but still some clouds near the summit.
If you had not changed your original estimate, that would have been impressive to predict a more accurate snow level than NWS, and doing so over 48 hours in advance of the storm. But still, it looks like your later snow level estimates were slightly more accurate than NWS. I don't think there were any tornados though.
