Hard Frost to End Midwest Growing Season

DES MOINES, Iowa (—Frost on the pumpkin and fragile hydrangea’s, and that may be the only impact of frost/freeze temperatures expected across the Corn Belt tonight and tomorrow. 

With the U.S. corn and soybean harvest paces at normal or above, crop damage from this freeze event is expected to be minimal.


Dan Hicks, Freese-Notis Weather Inc., says that much of Midwest will have frost/freezing temps over the next 2-3 nights.  

“Lows tonight will be in the upper 20s/low 30s, as far south as central into northeastern Nebraska, west-central into northern Iowa, and southwestern Wisconsin,” Hicks says.  

On Sat. morning, frost temperatures are expected as far south as parts of central into eastern Iowa, northeastern Missouri, and

central parts of Illinois and Indiana, Hicks says.  

“On Sunday morning, much of IN, OH could be recording frost temperatures. Some

northern areas of Midwest will likely have some mid 20s, during this time,” Hicks says.   

This cool spell will likely end the growing season in many areas, except some southwestern into south-central parts of the Midwest, Hicks says. “But, I don't think there will be much summer crop impact as a large part of the crop has been harvested & what is still in the field is likely mature & beyond potential harm from freezing temps,” Hicks says. 

Perhaps some fall fertilizer applications will be delayed. 

Looking ahead, a warm up will occur starting in western Midwest Sunday then spreading eastward into early next week, Hicks says.


Kyle Tapley, MDA Weather Services meteorologist, says the latest U.S. Drought Monitor is showing more concerns for the middle states of the country. Drought conditions increased last week, with 32.62% of the contiguous U.S. in drought, compared to 31.58% last week,“ Tapley stated in a daily letter to customers. “Most of the increase occurred in Texas and the Delta, where drought is becoming more extreme. Moderate drought is showing up in the southern Midwest.”


Tapley adds, “A possible tropical system in the Gulf, could bring much-needed rainfall in the net few weeks.”
