After a major snowstorm to end last week, another storm is cranking up to our southwest and is expected to bring more snow to the state tonight into Tuesday. Is it common to have back to back snowstorms like this? The featured chart presents the frequency of having a snowfall event within the 2 to 5 day period after a day with or without snow. Day 1 is skipped since it is hard to differentiate two day snowfall events from the same storm. The frequencies are partitioned by the snowfall total. There appears to be an interesting signal in this chart with the frequencies peaking for days after a three inch total. While the blue bars represent all cases, the red bars denote when the subsequent snowstorm produced a daily total larger than the one proceeding it. So when there was an eight inch plus event, the next snowstorm within two to five days was less intense for Des Moines.
