Weather & Harvest Updates

The USDA’s July 27 bulletin reports dry weather across most of the Midwest, with temperatures in the upper Midwest on the rise. Soil moisture reserves tempered the impact of hotter, drier conditions across the central and southern Plains. Large portions of the Northeast, Southeast, and Southwest saw significant rainfall. Heavy rains in the Southwest brought some drought relief, as well as the occasional flash flood. Overall, temperatures ranged from above average in the northern Plains to below average in the Northeast and southern Plains. Wildfires continued in northern California and the northern Rockies.


The winter wheat harvest moved into its final stages.

Winter wheat is now 84% complete — 3 points ahead of the five-year average.

97% of spring wheat acres are headed — on par with the five-year average. Only 9% of the crop is in good to excellent condition, 61 points behind last year. 

Barley is 96% headed — equal to the five-year average. 22% of barley is in good to excellent condition, 58 points behind last year.

31% of oats have been harvested — 2 points above the five-year average. Quality is 36% good to excellent, 25 points below last year. 

Corn development remains highly variable within some fields.

79% of corn has reached the silking stage — 6 points above the five-year average. 18% is in or beyond the dough stage, 1 point ahead of the five-year average. Nationally, 64% of corn is in good to excellent condition, 8 points behind last year.

Here are the states with the highest good to excellent ratings and the states with the highest poor to very poor ratings:

Good to excellent — CO, IL, IN, KY, MI, NE, NC, OH, PA, TN, and WI.

Poor to very poor — MN, ND, SD, and TX.
