Top 10 November Snowfalls
Date: 03 Dec 05:30 AM

Bad: 0 Abstain: 0
The snowfall from this past weekend was quite intense for November. The featured chart presents top 10 daily snowfall totals for Des Moines during the month of November. There are caveats galore with such a listing including difficulties of snowfall measurement, varying periods of record, and most importantly: snowfall events are typically long duration and often cross arbitrary 24 hour boundaries more so than heavy rainfall events. All those caveats aside, the total from Saturday at 8.9" comes in third place for the month of November. This was also the case for Waterloo, with its 9.3" coming in third place as well.
