St. Louis — Rains that eased or stabilized parched conditions in some key farming states haven't helped growers and ranchers in Kansas or Nebraska, where the severity of the drought continues to spike, a climate monitoring center showed Thursday.
Storms that rolled through swaths of the nation's midsection last week offered some respite to farmers punished for months by the widest U.S. drought in decades. Nonetheless, rainfall so late in the growing season might not meaningfully improve yield expectations that the federal government has downgraded for two straight months.
The U.S. Drought Monitor map released Thursday showed that the amount of the contiguous U.S. mired in drought conditions dropped less than 1 percentage point to 61.8 percent as of Tuesday. The portion enduring extreme or exceptional drought — the two worst classifications — also eased, to 23.68 percent from 24.14 percent.
In Iowa, the nation's leader in corn production, the amount of land classified in those two most-serious categories dropped 7 percentage points to 62.05 percent over the past week, thanks to the recent storms.
"Other areas, such as the Southern and Central Plains, were not as lucky and continued to dry out," the National Climatic Data Center's Michael Brewer wrote in the update, released weekly by the National Drought Mitigation Center at the University of Nebraska in Lincoln.
The amount of land in Nebraska suffering exceptional drought spiked by 19 percentage points to 22.5 percent, while that number in Kansas jumped from 38.6 percent last week to 63.3 percent now. Illinois, another key supplier of corn and soybeans, saw its conditions abate slightly, with the amount of land in the two worst drought categories slipping from 81.18 percent to 79.54 percent.
The U.S. Agriculture Department has twice slashed its forecast for this year's corn and soybean output because of the punishing drought in the nation's breadbasket. It forecast the nation's biggest harvest ever in the spring, when farmers planted 96.4 million acres of corn — the most since 1937. But the agency cut its estimate a month ago and again last Friday, saying it now expects the nation to produce 10.8 billion bushels, the least since 2006.
If that estimate holds, the federal government says it will be enough to meet the world's needs and ensure there are no shortages. But experts say food prices will almost certainly climb as corn is a widely used ingredient found in many products including cosmetics, cereal, colas and candy bars.
The USDA's latest estimate predicts corn farmers will average 123.4 bushels per acre, down 24 bushels from last year in what would be the lowest average yield in 17 years. But the yield would still be as good as nearly a decade ago, when the average was about 129 bushels in a year without drought.
The drought stretching across the U.S. from Ohio west to California is deepest in the middle of the country.
