State Climatologist Harry Hillaker says Iowa didn’t see as much rain as it normally does during the month of May. “Preliminarily, it looks like May for the most part was a little bit on the warmer side than usual, thanks to a very warm end to the month,” Hillaker says. “And also most of the state was a bit drier than usual, with precipitation averaging out to about an inch and a third or so less than usual.”
Here in Atlantic, at the KJAN studios, we received 3.41-inches of rain. Normal for the month is 4.32. Hillaker says it has been awhile since we’ve seen a May like this. He says it was the “Driest May in eight years, and also the driest spring in nine years.” There was another weather issue of note in May.
Hillaker says “Usually May is a pretty big month for severe weather, didn’t really have a large amount of severe weather, did have some. But overall, a little bit quieter than usual.” The average High for the month of May in Atlantic was 74 (normal is 73). The average Low was 49 (normal is 49). Hillaker says the month of June will be off to a stormy start in Iowa with above normal rainfall and near normal temperatures.

Officials with the National Weather Service say they are forecasting severe weather and flash flooding to become major threats to much of Iowa this upcoming Tuesday evening into Wednesday morning.
The latest forecast from the Storm Prediction Center shows the main threat for severe weather across the U.S. Tuesday will be across Iowa — mainly from Interstate 80 south. Heavy rainfall is expected with these storms. At this point, it shows a more than 45 percent probability of severe weather with the main threats of large hail, tornadoes and widespread damaging winds.
A combination of a much higher than usual amount of available moisture plus very strong wind shear will lead to a strong potential for severe thunderstorms. The storms are likely to move into western Iowa by around midnight, Tuesday. Tornadoes may occur during the overnight hours, so make sure you have a way to receive warning information near your bed before going to sleep.
Several inches of rainfall are also possible by and during the Wednesday morning commute. This could lead to flash flooding in flood-prone areas. Additionally, the Des Moines metro is expected to be impacted by this rainfall, so plan for extra travel time during the Wednesday morning commute.
