U.S. Midwest Enters Deep Freeze

Brazil’s soybean planting season rolls on.

DES MOINES, Iowa -- Though snow and frigid temperatures are coming, U.S. farmers have a mostly clear weather window to finish harvesting corn and soybeans, according to the latest outlook.

Dale Mohler, AccuWeather meteorologist, says the U.S. harvest weather should cooperate this month, as Brazil’s soybean planting season continues to experience favorable weather, too.

The U.S. Midwest weather pattern is changing this week to a drier and colder one.

“The pattern is not 100% dry, but a lot of times if it goes colder, it means the northwest flow aloft shuts off any Gulf moisture from getting up into the Midwest,” Mohler says. So, that will be the case for the next 10 days, Mohler says.

As of Sunday, USDA pegged the corn harvest at 76%, slightly below the prior five-year average of 77%. Soybean collection was 83% complete, behind an 89% five-year average.

Frigid Temperatures Arrive

Snow is expected Thursday and into Friday across Kansas and Nebraska.

“And then there will be a storm, next Monday and Tuesday, that will impact the eastern Corn Belt. That could bring rain or snow to Ohio and Kentucky,” Mohler says.

Outside of that, especially for the northwest corner of the Corn Belt, it looks fairly cold, but dry all the way to next weekend, he says.

The weather pattern is ending the growing season for much of the nation, for sure, he says.

“The temperatures will be in the 20s and 30s, by day, across the north and 30s to 40s in the south. And the temperatures will dip down to the teens and 20s by night.”

He added, “This should be favorable for harvest, as we get closer to the finish line.”

Temps Bottom

Early next week, U.S. Midwest temperatures bottom out, Mohler says.

“We will see more seasonal temperatures, beginning next week lasting through November 18,” he says. And the week of Thanksgiving should bring moderating temperatures, possibly above normal. Cold weather will retreat into Canada the week of Thanksgiving.”

Rain will return for parts of the Corn Belt the week after Thanksgiving, he says. Moderate rainfall amounts are expected, causing some harvest delays.

Brazil Planting Weather

There is good news for Brazil’s soybean planting season.

“They have had some widespread rains in the last few weeks. But dry weather since last weekend has helped planting progress,” Mohler says.

There will be a break in the rain, for the southern part of Brazil, for this week, he says.

It has dried out in southern states of Rio Grande do Sol, Santa Catarina, Parana, and even farther north into Mato Grosso do Sol.  

“We’re seeing eight to nine consecutive dry days on tap, going forward, for southern Brazil. So that should push planting season a long way. Farther north, showers and thunderstorms are expected everyday for the next two weeks,” Mohler says.

Weather experts are keeping an eye on a developing El Niño weather pattern for Brazil, impacting crop growth in December.

“In northern Brazil, the developing El Niño (a dry pattern) could impact crops further into the growing season spanning from December into February,” Mohler says.
