The last three days of May are forecast to have near no chance of severe weather and will wrap up a rather quiet month for such storms. The featured chart presents the IEM computed monthly NWS Tornado Warnings issued for Iowa since 1986. Only one such warning was issued this May and that was back on 20 May by NWS Davenport. The chart nicely shows that such a low count during May is not all that exceptional with it happening as recently as 2021 and a number of years previously. Heat and humidity do look to build going into June along with more robust chances of severe thunderstorms.
