AccuWeather.com reports following what has been the driest four-month period since before the 1930s Dust Bowl, hope is dwindling, if not already lost, for many wheat farmers in the nation's largest production region that desperately need rain.

For those who still have hope, rainfall over the next six weeks or so will be extremely critical. A drier-than-normal forecast through May does not bode well.

Any hits to U.S. agriculture amid rising food and gas prices will only add to the strain on the wallets of families and individuals across both the nation and the globe, with the U.S. being the world's largest exporter of wheat and corn.

All eyes on Kansas now

According to AccuWeather.com Agricultural Meteorologist Dale Mohler, the percentage of U.S. wheat considered "poor" or "very poor" increased from 32 to 36 in just the past week due to lack of rain in the southern Plains and Southwest.

Reports have even said that many wheat farmers have considered switching to another crop altogether this year.

"There will not be much of a crop in western Texas and western Oklahoma," Mohler said. "Now the focus is on Kansas and eastern Oklahoma."

As AccuWeather.com Staff Writer Gina Cherundolo pointed out, "Texas, Oklahoma and Kansas combined produce more than half of the nation's winter wheat crop, with Kansas alone producing about a quarter."

Mohler said Thursday that while there will be storm systems moving through the Plains over the next 10 days, rainfall will only benefit the region temporarily. More rain is needed on a regular basis through May.

With a storm system pushing through the Plains Thursday into Friday of this week, the most substantial rainfall will target areas from eastern Oklahoma and Arkansas into north-central Kansas, Nebraska and Iowa with 0.5 to 1.0 inch possible. Little rain is expected in areas farther south and west.

Severe thunderstorms in forecast

Unfortunately, it will be severe thunderstorms capable of producing tornadoes, damaging winds and large hail that bring the much-needed rain. For the wheat crop, large hail will be the main concern with isolated damage possible in some fields.

Several more storm systems will track across the Plains next week. Eastern parts of Kansas and Oklahoma may benefit from at least one of these storms, while rainfall totals may only amount to about half an inch into southwestern Kansas through next week.

"A half an inch of rain alone is not going to save the crop," Mohler stated. "It would help, but it's not going to save it. They need more rain following it in May, and that just seems unlikely with a forecast for continued drier-than-normal conditions."

In northeastern Kansas, however, Mohler said there is more hope. "I feel confident that the rain over the next week and a half will help the crop in northeastern Kansas and that they will have a greater opportunity to get more rain into May."

"Central Kansas will be on the fence," he added. "It could go either way."

More on the drought and other impacts

According to the latest release from the U.S. Drought Monitor on April 7, 2011, a severe to extreme drought is affecting a large area from Louisiana and Arkansas to Texas, New Mexico, Arizona and Colorado.

In addition to causing significant crop damage, the drought has also been contributing to an extreme risk of wildfires over the past couple of months, especially from western Texas into Oklahoma and Colorado.

Wildfires in western Texas over this past weekend reportedly scorched more than 230,000 acres and destroyed approximately 80 homes and buildings.

The threat for wildfires is likely to remain high across the region through the rest of the spring and summer with drier-than-normal conditions predicted.

The fire danger becomes especially high when storm systems kick up high winds across the area. Gusty wind events tend to be more common during the spring than summer.

Much of the rest of this week, areas from New Mexico into western Texas will remain at an elevated risk with gusty winds in the forecast.
