Map: US Summer Forecast Less Favourable for Soybeans




AccuWeather’s summer forecast looks relatively favourable for this year’s US corn crop but less so for soybeans.


Released last week, the US seasonal forecast suggests the first part of the summer will feature frequent thunderstorms across the Northeast, Ohio Valley and Midwest, limiting the potential for long-duration heat waves with temperatures averaging right around normal.


But as the calendar flips from July to August, there will also be a flip in the weather pattern that will open the door for the hottest conditions of the entire summer. “We could have a dry spell later in the summer that could spark some intense heat for a time,” said meteorologist Paul Pastelok.


Corn typically goes through its most important stage of development in July, with plenty of moisture and moderate temperatures during the month helping to maximize yield potential. On the other hand, the change to hot, dry conditions later in the summer could threaten soybeans, which go through the most important stage of development in August.


Still, conditions may not be totally ideal for corn either. The AccuWeather forecast warns that several rounds of stronger storms could impact the Midwest, particularly in June and July, in addition to garden variety summer storms that pop up on warm and humid afternoons.


The most active zone for severe weather is predicted to be around Minnesota, Iowa, Illinois, Wisconsin and Missouri, and it is possible the region could even see another derecho. On Aug. 10, 2020, a particularly strong derecho blasted across Iowa with winds greater than 100 mph. The storms leveled entire fields of crops and caused billions of dollars in damages.


But while storms could be disruptive, AccuWeather said the moisture will be beneficial for some areas of Midwest as well as the US northeast, where pockets of moderate drought have sprung up in recent months. “I think a majority of those pockets will go away by the middle of the summer,” Pastelok said.


In contrast, much of the central Plains, including already drought-plagued North Dakota, is expected to remain dry and hot this summer, according to the AccuWeather forecast.
