Getting a bit of snowfall during October is not all that uncommon as shown by the featured chart comparing October snowfall totals with total precipitation for Des Moines. Of course, getting snowfall this early in October is a bit rare and we are already well above average for precipitation amount for the month. The long term average snowfall is just 3 tenths of an inch, so hopefully we stay below average for the rest of the month! The current forecast looks dry for at least the coming week, which is much needed to help farmers again make some progress with the harvest.
