What happened

The episode as NWS FSD wrote it up.

After a wintry mix of precipitation on December 12 and a warmup to allow mainly rainfall on December 13, temperatures fell with a change to snow. Snow and stronger winds began earlier in the day December 14 west of the James River, with the transition to snow mainly later into the early morning hours of December 15 toward Interstate 29. With northwest winds gusting at times from 40 to 55 mph, several areas exhibited periods of blizzard conditions on the 15th and early on the 16th. The heaviest snowfall occurred from the James River Valley westward, where up to 10 to 17 inches was common.
