One of the things that makes spring time in Iowa problematic is that the period often features a number of snow storms in between stretches of nice temperatures that feel nothing like winter. The featured chart highlights the last trace plus snowfall reported by Des Moines for each year on record, how long that snowfall stuck around and the accumulated frequency of having it be the last snow of the season. So for April 11, approximately half of the previous years on record have at least one trace plus event after the date.
