While a few severe thunderstorms are possible today, the severe weather season is generally winding down. The featured chart presents the frequency of having a severe thunderstorm warning in Iowa by week of the year. The top chart shows the number of years since 1986 that had at least one warning for that week and the bottom chart shows the overall number of events. The transition from September into Octobers shows the downward trend in activity with very few events found for the month of October.
