Corn, Soybean Growing Conditions Favorable in June

June is shaping up to be a good month for farmers across the Midwest. Forecasts for the next two weeks show normal to above-normal rainfall for the majority of the Midwest, says Dale Mohler, senior Accuweather agricultural meteorologist.

“Over the next two-week period there will be a wetter pattern than we’ve had the past two weeks,” says Mohler.

Areas with topsoil dryness from lack of rain the last few weeks – central Indiana, northwest Ohio, central Illinois, northern Missouri, southwest Minnesota, and southeast South Dakota – will all see rain. “Not necessarily enough to wipe out all of the small deficits that have built up, but it will be close,” says Mohler, adding total rainfall for these areas will span between 1 to 1.5 inches.

This Week

Rain is forecast in the West over the next few days, hitting Minnesota, Nebraska, Iowa, and the Dakotas. The majority of the area will have 1 to 1.5 inches, but portions of Iowa and Nebraska could get as much as 2 to 3 inches of rain, says Mohler. “Those are really good rains early on,” he adds.

Farther east is dry today and tomorrow before rains will move across Wisconsin into Michigan Thursday night with precipitation totals estimated at 1 to 1.5 inches. On Friday and into Saturday, the storm will continue through Illinois, Indiana, and Ohio, bringing .5 inch to 1 inch of rain.

“Later in the weekend, rains get pushed south by a big high-pressure area that will push the front and rain down into the Tennessee Valley. So, most of the Midwest is dry by late in the weekend,” says Mohler.

During this time frame, the majority of the Corn Belt will have temperatures in the 70s and 80s with 90s popping up in Missouri, southern Illinois, southern Indiana, and western Kentucky.

Next week will start off cooler with most places in the 60s and 70s. Temps will warm up in the middle of the week with 90s forecast Thursday and Friday for the southwestern portion of the Midwest. Rains will accompany the cooler temperatures.

“Monday and Tuesday there will be rain marching from the west to east across the Corn Belt with .5 inch to 1 inch in the west and a little less in the east,” forecasts Mohler. “Another system will move through Thursday on into Saturday, bringing 1 inch in the west and 1.5 inch to the east.”

Week of June 18

Rainfall gets more difficult to predict further out, but Mohler anticipates normal rainfall of ¾ to 1 inch of rain for the week of June 18 to 24.

For June, “there aren’t any dry stretches to speak of,” says Mohler. “There are always places here and there that get less rainfall, but those will usually make up for that at some point with a favorable weather pattern.”

The week of June 18, temperatures will be below normal in the north – in the 70s – and close to normal in the south – low to mid-80s.

“There are really no significant problems as far as heat, although there will be a few hot days this week and next,” says Mohler about June overall.

Moving Into July

Unfortunately, the forecast doesn’t look as rosy for July.

“What we are concerned about down the road is dryness that will start to show up in the central Plains combined with heat that will expand eastward into the western third of the Midwest,” says Mohler.

This swath of dryness with below-normal rainfall predicted spans from Missouri, into Iowa, Nebraska, Minnesota, and the eastern Dakotas. “That’s the critical period for corn during pollination,” says Mohler.

Another area of concern is the lower Mississippi Valley where conditions have already turned dry, and this looks to continue through the summer. “That could put some stress on soybeans, resulting in production losses,” adds Mohler.
