DES MOINES - Iowa Secretary of Agriculture Bill Northey commented on the Iowa Crops and Weather report released by the USDA National Agricultural Statistical Service. The report is released weekly from April through October.
"The cooler temperatures and rain showers that moved in this weekend were welcome relief after another week of hot and dry weather further stressed corn and soybeans," Northey said. "Harvest remains delayed because of the late planting and cooler weather for much of the growing season."

Unseasonably hot weather continued over most of Iowa through Wednesday (11th) with much cooler air prevailing for the remainder of the week.
Temperatures reached 102 degrees at Donnellson and Keokuk on Monday (9th). These were the highest temperatures recorded so late in the year for Iowa since September 28, 1953. However, morning low temperatures fell to 39 degrees at Cresco on Friday (13th) and down to 36 degrees at Belle Plaine, Lowden and Williamsburg on Saturday (14th). Temperatures for the week as a whole averaged 6.4 degrees above normal.
As the cold front slowly made its way across Iowa from Tuesday evening to Thursday morning showers and thunderstorms brought light to moderate rain to much of the state. Another area of rain moved across the state from late Saturday (14th) into Sunday (15th) afternoon. About one-half of the rain from the second system fell after the cut-off for this report and will be included in next Monday's report.
Nevertheless, a few areas were missed completely by the rain with locations such as Sheldon, Sioux City, Storm Lake and Jefferson receiving no measurable rain. Precipitation of greater than inch was confined to relatively small areas over the southern one-third of Iowa.
The maximum reported rainfall was 2.60 inches near Promise City in northeast Wayne County. The statewide average precipitation was 0.33 inches while normal for the week is 0.81 inches. This was the seventh consecutive week, and tenth of the past eleven, with below normal rainfall.
