Done with snowfall?

The featured chart displays the date, amount, and the duration that the last snowfall of the season stuck around for Des Moines. The calendar now says 23 April, which comes in at about 92% on the chart. So about 8% of all previous years had another measurable snowfall on this date or later. The forecast continues to be optimistic that we are done with the snow this season, but it would certainly help to have another week pass by to be more confident.
