Rain, Cooler Temperatures Next Week Will Ease Midwest Crop Stress

Posted on 07/10/2018 10:58 AM

Cooler, wetter weather will break the stress on corn and soybeans starting July 15 after hot, dry conditions across the Midwest this week temporarily stress plants. May and June are likely to be the warmest since 1934, the main reason corn development has been so rapid this year. Corn planting on May 13 was 62% complete, the slowest in four years, according to data from the USDA. By July 8 corn that was pollinating jumped to 37%, the most since the drought of 2012.

 

“We have yet to see what the impact of the fast development will have on eventual yields,” said Don Keeney, senior meteorologist at Radiant Solutions LLC.  “This is uncharted territory with the hot overnight temperatures this week.”


Temperatures next week will cool to near average and most areas of the Midwest will get 0.5 inch to 1 inch of rain next week as two storm fronts move through the Midwest.  Heaviest rain expected across parts of southern Minnesota, Iowa, northern Illinois and Wisconsin with lighter rainfall amounts south and east, especially from southern Missouri into the Mississippi Delta where stress may continue. Today’s forecast is little cooler next week than expected on Monday.

 

“The cooler temperatures and rain should aid most crops,”  Keeney said.  ``It doesn’t look like the heat will return after next week’s rain. It’s a pretty good outlook.”

 

Crop stress may continue across some southern Canadian growing regions. Rains this week will aid about two-thirds of the wheat, canola and other crops across the Canadian Prairies with a third remaining too dry in southern Alberta, Saskatchewan and Manitoba, Keeney said.
