While the featured map does not include the ongoing snow storm this Wednesday, the season to date snowfall departures are presented. The values are as reported by the NWS CLI/first order sites. Davenport has one of the largest departures shown on the map at nearly three feet! Even within Iowa though, there are some negative departures over far northwestern Iowa. The ongoing storm may erase those though. We'll have another big storm system for the upcoming weekend as our wild winter rolls on.
