The National Weather Service (NWS) 90-day outlook calls for “equal chances” of above-, below- and normal temperatures from August through October across virtually the entire Corn Belt. But the remainder of the country is expected to see above-normal temperatures. That leaves open the possibility the growing season could extend longer than normal, which most crops need after the extreme planting delays.
The 90-day outlook calls for above-normal precipitation over most of the western Corn Belt and western Illinois. Other areas of the region and the South area expected to have “equal chances” for above, below and normal precip through October.
While the NWS forecast leaves open the chance for an extended growing season, World Weather Inc. says there is statistical evidence against that happening. The lunar cycle and the solar minimum are aligned this year, which World Weather says provides greater-than-usual potential for early frost and freezes in the north-central states.
The shorter-term outlook for August is also getting a lot of attention given the late start to the growing season. NWS’s outlook favors cool conditions over the Dakota and Nebraska and “equal chances” elsewhere across the Midwest.
The one-month outlook also gives higher odds for wet weather on the Northern Plains and western Corn Belt. The weather-watcher gives basically a non-forecast on precip for the rest of the Midwest.
