Quiet April

Posted: 23 Apr 2021 05:37 AM

Iowa's severe weather season typically gets started in earnest during April, but this year has been very quiet so far. The featured chart presents the monthly number of Severe Thunderstorm Warnings issued for Iowa. The mere four total for this April is easily the lowest over the past twenty years and one has to go all the way back to 1993 to find as low a total. Of course, there are still eight days worth of this April to go, but the forecast is not very optimistic for severe weather reaching this far north over that time. While very few people want damaging thunderstorms, they do coincide with needed spring rainfall, which has also been generally lacking over much of the state. Back to the chart, June is clearly the peak month for these thunderstorms with June of 2008 being the epic month for severe weather for Iowa over the modern record.
