July 2017 Precipitation in Top Corn & Soybean States

By Joel Karlin , DTN Contributing Analyst

NOAA released its July 2017 state of the climate report earlier this week and noted that for the country as a whole July precipitation totaled 2.74 inches, 0.04 inch below the 20th century average and was near the middle value of the 123-year period of record.

Above-average precipitation in the Southwest, Midwest and Northeast offset below-average precipitation in the Northwest and Northern Plains.

A closer look however shows large disparities in July precipitation specifically in the Plains and Midwest.

This graphic shows July precipitation in inches for the top 21 corn and soybean producing states with three states producing just corn, three producing just soybeans and 15 others top producers of both crops.

2016 and 2017 readings are on the left hand axis and the July 2017 rain as a percent of the 1960-2016 average is on the right hand axis.

We also show where the last month's precipitation total ranks from the period 1960-2017 with 1 being the wettest of those years and 57 the driest.

As opposed to this year, last year's corn crop was in far better condition and had greater yield potential than the 2017 crop.

This is in part due to ample July rains in most key states last year as only Colorado, Ohio, Pennsylvania and Texas had significantly more rain this July than a year ago with Indiana and Tennessee slightly wetter.

What is interesting is the number of states that had July rains well below the 1960-2016 average including top state Iowa at 67.7%, Kansas at 68.5%, Minnesota at 67.3%, South Dakota at 80.9% and the driest of all being North Dakota at 46.9%.

This is why North Dakota had the 4th driest July since 1960 with Iowa also in the bottom third of their usual July precipitation figure.

Note that many of the dry states in the Plains and Western Corn Belt also had less than average June rains which is reflected in the second lowest corn ratings as of the beginning of August since 2007.

But yet USDA comes up with yet another bumper crop for 2017.
