DES MOINES, Iowa –A devastating weather event, known as a derecho, struck Iowa on August 10, 2020. A line of severe storms extended more than 770 miles for 14 hours. Sustained winds lasted almost an hour over a large swath of Central and Eastern Iowa, causing catastrophic damage to structures, crops and trees. Communities across Iowa were left with a trail of destruction after the storm. Over the past five years, the Iowa Department of Natural Resources (DNR) and Iowa communities have worked towards rebuilding and recovering the tree canopy lost in the destructive storm.

(Radio Iowa) – Trees weren’t the only thing knocked down by the derecho that blew through Iowa last week. Gary Knight sells sweet corn at stands in Cedar Rapids and Marion, and tells K-C-R-G T-V he knew some of his corn would have damage. “You know I’m almost afraid to go look at the corn the next morning to see what happened,” Knight says. Over 60 mile and hour winds ripped through the farm, knocking down ten percent of Knight’s sweet corn. “The most vulnerable corn is the corn that’s just ready or ripe, and it has the heavy weight on it. So when it blows down, it’s not going to come back up again,” he says. Some of the corn from those fallen stalks is salvageable, but Knight says he can’t harvest the corn with a machine because of the damage and will have to use the old-fashioned method of picking.

“Go out there by hand, walk through it, bend over, pick them and get them in the wagon. So it’s just a whole lot more work, and hard to find people who’ll go out and do that,” Knight says. The farm lost a total of five acres from the storm that’s now been classified as a derecho. “I’m going to call it ‘monsoon weekend,” Knight says.

That loss of product means some stands are closed for now. As they work to pick up the damage and the crops he said they do still plan to have sweet corn available through September.

(Radio Iowa) – State Climatologist Justin Glisan says the drought-busting rains of July pushed the month to near the very top of the state record book

He says it will be a July many people will remember for the big storms.

He says we were another big rain event away from the July record.

Glisan says the early dry months of the year kept 2025 from being another flood year like 1993.

Glisan says there were two main sources of moisture that led to ample July rain.

Glisan says he gets asked a lot about the so-called “corn sweat” where moisture comes off the 13 million acres of corn in Iowa. He says it is another source of water that leads to rain.

Glisan says the heat dome that set up around the third week of July led to heat indexes in the triple digits, but not record heat.

Glisan says that heat did spawn storms, including the derecho that barreled across the state.
