With just one more day of October to go, we might as well look forward to November. While the forecast starts off the month warm, the chances of measurable snowfall during the month significantly increase over October. The featured chart presents the November totals of snowfall vs precipitation for Des Moines. The value for last year is highlighted on the chart. The contoured areas are increasing population densities. This chart shows an average snowfall total of 2.5 inches, but plenty of zeros are plotted as well. It is interesting to see that increasing precipitation totals for the month do seem to increase the chances of more snowfall as well. This is likely due to the source of significant precipitation events being blockbuster storm systems that will feature a strong cold air side with associated snowfall. At this point, we desperately need rain and I am unsure though how many people are that desperate to have it fall in the form of snow!
