'20-'21 Winter Storm #25

While not much of a "winter storm", a very annoying late season snowfall came in two waves on Monday and Tuesday with the heaviest totals of an inch or two confined to west-central and far southern Iowa. The featured map struggles to capture the event as snows that quickly melt before routine daily reporting times cause ambiguity with reported amounts. Creating a snowfall map still seems appropriate and hopefully caps off the snowfall producing winter storms for the season. Some additional light flurries are falling this Wednesday, but should not amount to anything of significance.
