Corn Belt temperatures moderate but rain still hit or miss

This is what late summer temperatures are supposed to feel like, especially compared to a warm August last year.

Following a rather hot start to August, temperatures in the Corn Belt moderated somewhat during the second week of the month. According to data from WeatherTrends360 the week-ending August 13, 2022 trended the 14th warmest and 14th wettest in the last 30+ years for the Corn Belt as a whole, with both variables trending very close to average for the week. This is a wholesale change from the same time last year when the growing region trended the fourth warmest and first wettest in 30+ years.

Colder than normal temperatures spread across the Western Corn Belt to start the week and pushed eastward as the week advanced, eventually being replaced again by warmer than normal trends by mid-week.

Rainfall for the week was varied and largely missed the Western Corn Belt, although an area from southeastern South Dakota through northern Iowa and into northern Illinois received 1 to 2 inches of rain during the week. Lighter showers were also present across the rest of the Eastern Corn Belt. 

Drought continues to be a concern across the Western Corn Belt and South Central United States. As of August 12, drought had expanded or deepened in parts of Iowa, Nebraska, Kansas, Oklahoma, and Texas. According to the United States Drought Monitor, less than 5% of Nebraska, about 16% of Kansas, and around 36% of Iowa remain drought-free. Meanwhile, nearly the entirety of both Oklahoma and Texas are experiencing prolonged severe to exceptional drought conditions statewide. 

As we head into the middle of the month, some rain may finally materialize for portions of the South Central United States. For the week-ending August 20, much of the Eastern Corn Belt is forecast to trend drier than normal while somewhat wetter trends are expected from southwestern Nebraska into Kansas, Oklahoma, and eastern Texas.

While the rainfall is much needed in these parts, a prolonged stretch of wetter weather would be needed to make a meaningful dent in the existing drought conditions. According to forecasts from WeatherTrends360, temperatures for the week will start on a much warmer than normal note across much of the Corn Belt but cooler trends quickly move into the Eastern Corn Belt and spread further west by mid-week through the weekend.
