October weather is expected to be cooler than normal across the central Corn Belt, according to the 30-day outlook from the National Weather Service (NWS). In a normal year, that could trigger ideas a killing freeze could end the growing season early. But with most of the corn and soybean crops maturing well ahead of normal this year, the October precip outlook is the greater focal point, especially after heavy September rains. But the NWS 30-day forecast offers little guidance, calling for “equal chances” of normal, above-normal and below-normal rainfall.
The NWS 90-day outlook calls for above-normal temps across all of the contiguous U.S. aside from the far Southeast, while above-normal precip is expected through much of the Southern Plains, South and East Coast. That combination of heat and rains would be favorable for U.S. winter wheat emergence.
