Warm, dry weather across the northern and eastern sectors of the Corn Belt helped corn planting and crop emergence catch up with historical averages, according USDA's National Agriculture Statistical Service.

The National Corn Growers Association reports that that planting has reached 78 percent, equal to the NASS five-year average. By May 14, corn growers had advanced planting by 50 percentage points in Ohio and 36 points in Indiana.

Warmer weather also helped the crop emerge quickly throughout much of the Corn Belt. For example, high temps in Minnesota has advanced crop emergence by  40 percentage points. The Illinois crop advanced 34 points during the week, NASS reports.

However, heavy rains in the nation's mid-section from Texas to Iowa halted fieldwork and flooded lowlands. Hardest hit was Missouri, where planting is 31 percentage  points behind last year and 22 points behind normal. Nebraska and parts of South Dakota are also wet.
