Hot In the Corn Belt as pollination kicks into high gear

Hot, dry conditions may stress crops during critical reproductive phase.

After a wet start to July, a drier pattern settled in during the second full week of July 2022, week-ending July 16, which was the eighth driest second week of July in 30+ years for the Corn Belt, according to data from WeatherTrends360. Temperatures ranged from warmer than normal in the western Corn Belt to near normal in the eastern Corn Belt. 

Heat will be the big story in the third week of July, week-ending July 23, with much of the Central United States seeing a heat wave. In fact, multiple days of +100F temperatures are expected from Texas to Kansas with widespread highs above 90F across most of the Central United States. According to forecasts from WeatherTrends360, this will be one of the hottest third weeks of July in 30+ years for the Corn Belt. The hottest weather is most likely in areas that are already experiencing severe soil moisture deficits and drought.

The hot weather hits at a critical time for the corn crop as many areas are in or are soon entering the pollination phase. Precipitation will be hit-or-miss with below normal precipitation expected for the region overall. The best chances for precipitation will be outside of the extremely hot areas, so generally in the eastern Corn Belt, while the central and especially the western Corn Belt are drier. Dry weather combined with extreme heat will be very stressful for crops, combined with pre-existing drought conditions across parts of the region and this spells potential trouble for yields.

Hotter and drier than normal conditions look likely through the end of July in the Corn Belt with a hot and dry final week of July. Again, the best chance for precipitation will be in the eastern Corn Belt and towards the Great Lakes as showers and thunderstorms will tend to ride up and over the heat dome bringing very hot weather to the western and central Corn Belt.
