AccuWeather.com said the Midwest soybean and corn crops may be stressed by high temperatures the week of July 18. Hot, dry weather moving into the region will produce the hottest temperatures of the year, according to agricultural meteorologist Dale Mohler.

Look for three days of temperatures in the mid to upper 90s in Missouri, Iowa and Illinois. Mohler said soybeans have the greatest need for moisture in August when they go through the pod-filling stage.
