This one's for you if you want to understand weather better! Join Dan Fillius, Iowa State University Extension Horticulture Field Specialist, and Dr. Justin Glisan, Iowa's State Climatologist, as they discuss what is happening in the world of Iowa weather. Every week during the main growing season we'll discuss recent weather, its impacts on fruits and vegetables, and provide a climate outlook for the coming week in Iowa.
