As harvest of spring crops wraps up rapidly with few problems, USDA Meteorologist Brad Rippey says there are several areas of concern with regard to winter wheat establishment.
"Probably the greatest concern stretches from the Delta, the lower Mississippi Valley on into the Southeast," Rippey said. "Those areas not only had a hot, dry summer but they've had a dry autumn so far and they also face the prospect of dry conditions for much of the winter due to the ongoing La Nina."
The cooling of parts of the Pacific Ocean by La Nina can have far reaching effects.
"Warm and generally dry conditions across the nation's southern tier," Rippey said. "Those areas, especially the areas that are already experiencing drought, are at great risk for drought development or intensification."
Tropical storm systems could help, but right now there is nothing out there expected to hit the drought areas.
