Dry Spring Featured in Central US Forecast

Northern state dryness has been enhanced by a very warm spell during the mid-February to mid-March period. “The last 30 days have been very warm — 9 to 10 degrees (Fahrenheit) above normal in North Dakota,” Guinan said. That warmer trend has also kept the Great Lakes from cashing in on a typical winter precipitation feature — lake-effect snowfall. “There has been a lack of Arctic air intrusion. We haven’t seen nearly as much,” said Guinan. “And, so, snowfall is quite a bit below normal along the shores of the Great Lakes.”

Conditions being warmer and drier highlight the forecast looking through the spring and into the summer seasons as well as over the north-central U.S.

Public and private forecasts call for April temperatures to average above normal. Precipitation shows the greatest potential for favorable amounts in the Delta and Ohio Valley. The April-May-June period focuses precipitation in the Great Lakes and Ohio Valley, with much less moisture farther west.

Summertime is where warmth shows up notably. “All of the country is painted red” to illustrate above-normal temperatures, Guinan said. In addition, precipitation has mainly below-normal totals in northern, western and central areas of the continental U.S. Only the eastern one-third of the contiguous U.S., from eastern Illinois to the East Coast, has above-normal precipitation forecast.

Forecast conference call participant Dennis Todey of the USDA Midwest Climate Hub said that prospects for a drier spring may likely result in earlier corn planting. “We could see earlier-than-average planting to go ahead and get moving,” Todey said. “With corn, if you can plant it early, you will — to get to tasseling before the hot midsummer.”

As for the chances of reduced row-crop yields because of summer dryness, Todey said such a decline is possible. “Large chunks of our corn area (will be) going in (planted) with less moisture. That lack leads to less moisture for corn tasseling. Is our risk increased this year? Probably a bit,” Todey said.
