Iowa's wild weather year — from drought to derecho

Tune in to Sept. 30 webinar to learn what’s going on with this year’s weird weather.

To say Iowa’s weather in 2020 has been unusual is an understatement. Iowa Learning Farms at Iowa State University will present a  webinar at noon Sept. 30, explaining Iowa’s wild weather in 2020 and what the outlook is for next year.

“With 95% to 99% of Iowa experiencing abnormal dryness or drought, and 57 counties affected by the derecho windstorm in August, most Iowans have been impacted by this year’s wild weather,” says Justin Glisan, state climatologist with the Iowa Department of Agriculture.

During the webinar, Glisan will discuss the initial drought formation and expansion across western Iowa, as well as the short- and long-term impacts of the drought on the growing season and this year’s crop production. Also, he will discuss the severe derecho that moved through Iowa on Aug. 10, producing widespread damage in rural and urban areas, including the extreme drought region in west-central Iowa.

Iowa weather has big impact

As the state climatologist, Glisan’s responsibilities include observing Iowa’s weather and maintaining and interpreting the weather data; making weekly recommendations to the U.S. Drought Monitor; and providing weekly and monthly climate summaries for the state. He also advises the Iowa secretary of agriculture on climatological matters that impact the agricultural sector, such as how trends in precipitation and temperature are changing.

Justin Glisan DIGGING DEEPER: Justin Glisan, state climatologist at the Iowa Department of Agriculture, interprets weather trends important for Iowa.

“Iowa’s weather and climate observations, which date back to 1872, help tell the story of Iowa agriculture, and how resilient and innovative the state’s farmers are and always have been,” Glisan says.
