'Big heat' to hit Corn Belt at pollination time

Residents of the Midwest should be sure to enjoy the mild temperatures of the next two days as it is going to be quite a while before we see temperatures this cool again. Big heat for next week remains a very big story in the Midwest weather forecast right now.

By Saturday highs of 90 or higher will cover all but far northeastern parts of the Midwest, but it will only get worse from there. By Sunday highs will be 95 and higher for Illinois. Highs of 90 or higher for all of the Midwest for the work-week period of next week is a given, but especially for Tuesday to Thursday it looks like highs of 95 and higher will be awfully common.

While most of the 100 degree highs will be in Nebraska, southwestern Iowa, Kansas, and Missouri, there will likely be scattered locations outside of that area that also make a run at the 100 degree mark at times next week.

Timing of the heat could not be any worse given the amount of corn that will be pollinating during that time frame. Making matters worse is that a fairly decent part of the eastern Corn Belt is likely going to be going into that heat having recorded rainfall a good distance below normal over the past two to three weeks (or more).

But let's face it: even in areas where soil moisture is going to be good heading into the heat, it is not good to be pollinating corn under the type of conditions that we are going to be seeing just after mid-month. Prior to the heat we are going to see additional big rains in northwestern Iowa, northeastern Nebraska, the Dakotas and Minnesota for especially today through a part of Saturday.

We will also be seeing a notable increase in afternoon and evening thunderstorm activity in the Delta and the Southeast for today through the weekend, and that will help to cool temperatures in that area (after the Delta suffered through big heat the past two days).
