Some rainfall was able to make it into western Iowa this past Friday, but did not amount to a whole lot. Interestingly, it was able to muster a thunder report from the airport weather station in Des Moines, which was the first such report this month. It only amounted to 0.02 inches though for the site! Anyway, June is the peak of thunder reports for Iowa with the featured chart presenting the 2021 hourly reports for Des Moines along with the simple average climatology with data back to 1973. There are caveats galore with a plot like this and how observation techniques for thunder have changed over the years, but the 2021 story is pretty clear. We should have seen many more thunder reports for this month, May and even April.
