Much of the northern Corn Belt has an increased chance of above-average precipitation in October, according to the NWS Climate Prediction Center. This follows on the heels of above-average precipitation over the last 30 days across the Corn Belt.
In the map below, areas shaded in green have an increased chance of above-average precipitation in October and include the Dakotas, Minnesota, Wisconsin, Michigan, Iowa, northern Illinois, and northeast Missouri.
On July 17, 2014, the NOAA Climate Prediction Center released their outlook for August and beyond.
Currently, we have significant heat through the High Plains and the Midwest. But it will be short-lived. The NWS forecast show cooler conditions returning soon to the region. The outlook for August (first map, click to enlarge) includes an increased chance of below-average temperatures across the upper Midwest, while the Southeast has as increased chance of above-average temperatures. Much of Illinois, Indiana, and Ohio have equal chances (EC) of above, below, and near-average temperature.
Much of the Corn Belt has equal chances (EC) of above, below, and near-average precipitation (second map) in August. In other words, there are no clear indications of an increased risk for too much or too little rain.
On June 19, the NOAA Climate Prediction Center released their latest monthly and seasonal outlook of temperature and precipitation for the US. One of the factors that will likely come into play this fall and winter is the developing El Niño event in the Pacific Ocean. Here is the breakdown of the outlooks. Unshaded areas show an equal chance of above, below, or near-average conditions and are labeled “EC”. Click on any map to enlarge.
There is an increased chance of cooler-than-average conditions in July for eastern Montana and Wyoming, northeast Colorado, western Nebraska, and nearly all of the Dakotas, Minnesota, and Wisconsin. The rest of the Corn Belt is in the “EC” category. At the same time, the Southeast has an increased chance of warmer-than-average conditions.
For precipitation, there is an increased chance of drier-than-average conditions in southern Missouri and Illinois. Meanwhile, there is an increased chance of wetter-than-average conditions in the Rockies and the western portions of the High Plains that could bring some relief to parts of drought-stricken Colorado, Nebraska, and Kansas.
