The first round of snowfall fell overnight with very light totals over the state. So it is likely a good time to check in on if having the first trace of snowfall is early or not. The featured chart presents the date of the first trace or higher snowfall for Ames, the number of days that snow stuck around, and the accumulated frequency of having such an event by the given date. The chart nicely shows that this first snowfall almost always does not stick around long. This is due to soil temperatures which are still generally above freezing this time of year and will work to melt any snow that falls. The next round of snow arrives tomorrow and will primarily impact southeastern Iowa with higher amounts of snow than what fell with this first round.
