Story highlights

  • Nearly half of the continental U.S. is experiencing severe drought
  • Almost all of Arkansas is in severe to exceptional drought
  • Oklahoma is expected to break the statewide 1936 temperature high record Thursday
  • More than half of U.S. counties are designated disaster zones

The area of the United States in extreme or exceptional drought grew by an area roughly the size of Alabama over the past week, according to new figures out Thursday.

Nearly half of the continental United States is in severe or worse drought, and the worst-hit area is the Great Plains, according to the latest report from the National Drought Mitigation Center at the University of Nebraska-Lincoln.

"You'd have to go back to the 1930s to find any drought as widespread as this one," CNN meteorologist Dave Hennen said.

About 93% of Missouri, more than 80% of Kansas and Nebraska and about two-thirds of Colorado fall into the two most severe categories.

More than 95% of Arkansas is in severe to exceptional drought, and Oklahoma is expected to break its all-time high temperature Wednesday, with predictions of 115 degrees in Norman. The record of 113 degrees was set in 1936 in Oklahoma City, CNN meteorologist Monica O'Connor said.

Cities throughout Oklahoma have implemented water restrictions, with Oklahoma City limiting lawn irrigation to every other day, the city announced Wednesday.

And things aren't looking up. The heat and dryness work together to worsen conditions, each making the other more extreme as time passes, Hennen said.

With a drought like this, it will take "a huge change in the system" like a tropical storm to break the pattern, he said. The Southeast and Southwest may see relief from such storms in the next few weeks, but that moisture is unlikely to reach the Plains states.

More than half of all U.S. counties have been designated disaster zones, the Department of Agriculture reported, blaming excessive heat and a devastating drought that's spread across the Corn Belt and contributed to rising food prices.

Agriculture Secretary Tom Vilsack made disaster zone designations for an additional 218 counties in 12 states Wednesday because of damage and losses caused by drought and excessive heat. The states are Arkansas, Georgia, Iowa, Illinois, Indiana, Kansas, Mississippi, Nebraska, Oklahoma, South Dakota, Tennessee and Wyoming.

Nearly three-quarters of the nation's cattle acreage is now in a drought-stricken area, as is about two-thirds of the country's hay acreage, the agency reported.

USDA researchers added that an average of 37% of the nation's soybeans were ranked last week from very poor to poor, the lowest quality recorded since a massive drought in 1988.

Nearly half of America's corn crop was also rated very poor to poor, while 57% of its pastures and range land were similarly graded.

This year's harsh conditions suggest that food prices next year could surge by as much as 4.5%, the agency reported.

"It's the most severe and expensive drought in 25 years," USDA economist Timothy Park said.

As the hot and dry weather persists, farmers face potential losses in spite of federal crop insurance meant to soften the blow to U.S. agriculture.

"The pocketbook is really taking a hit," said Robert Dickey, a 58-year-old farmer in Georgia whose losses are just below the threshold needed for his insurance to kick in.

"We'll probably have to take out some loans to get us through to next year."

The price of milk, cheese and other dairy products is also expected to surge, while ranchers face steepening feed costs.

"When I was a kid in the '50s ... it got real dry, but nothing like this," said Marvin Helms, a 70-year-old farmer and rancher in central Arkansas who was compelled to sell his beef cattle after being short on feed.

His thousand acres of farmland near Arkadelphia include corn and soybeans, which Helms says is normally sufficient to sustain his family and provide for his cattle.

"We've got some insurance on the crops, but it's not enough," he said. "It will help, but it won't pay the bills."

Historic drought puts over half of U.S. counties in disaster zones

Still, economists say the extent of federal insurance coverage -- which includes about 85% of the nation's crop acreage -- will help protect farmers against catastrophic income losses.

"Today's safety net is going to protect a lot more of those producers than in the past," said USDA Deputy Chief Economist Robert Johansson. "Though it's hard to say the what effect will be on an individual producer, because a lot of times, these crop producers are also producing livestock."

In an effort to bolster assistance, the USDA expanded emergency disaster assistance Wednesday to allow for haying and grazing on 3.8 million acres of protected conservation areas, once considered off-limits.

The agency also reported that crop insurance companies have agreed to allow for a "short grace period for farmers on insurance premiums in 2012," giving farmers an extra 30 days to make payments without interest penalties on their unpaid premiums.

But while a variety of crops are strained across the U.S. Midwest, a top concern for policy-makers is corn.

"The unusually hot and dry conditions coincide with the period of pollination and kernel formation, which sharply reduces estimated yields," the USDA reported. "As of July 17, approximately 88 percent of the corn crop was in regions impacted by drought."

About 75% of all food found in the supermarket contains corn, officials say.
