Wow I wish I could have experienced that! Are there any local snowfall totals from the area? Even if the totals aren't spectacular, it sounds like a very exciting event with all sorts of heavy precip culminating in a short duration heavy snowstorm/blizzard!
It kind of seems like to me like a better version of March 2005-- remember that-- started as rain, temperatures crashed and it changed over to heavy snow.
Another one which was like that (actually two) were the latter events in February 2010. Both started out as rain and changed to heavy snow, one changed right in the middle of the day and the other one later in the afternoon. Both gave us a foot of snow after we had had an inch of rain.
