Daily Snowfall Climatology

Posted: 30 Sep 2022 05:30 AM

With the calendar turning to October on Saturday, we can certainly now start taking about snow. The featured chart presents the simple daily average snowfall based on available data since 1951 for Des Moines. The plot has a lot of noise in it as individual heavy snowfall events will skew the day to day averages. The flat line of zero through September now starts to get a little life to it during October, but snowfall events are still rare for the month. The teeth of winter starts arriving in December for snowfall and so hopefully we can continue to enjoy nice fall weather until that reality arrives until we reach next April and May.
