Widespread rainfall evades Corn Belt Into early September

Heavy rain concentrated in the South continues to improve drought conditions.

Spotty rainfall across the Corn Belt and Midwest in the latter half of August resulted in mixed results for drought conditions. Drought improvement was seen in Minnesota, northern Wisconsin, Michigan, parts of central Indiana, and southern Missouri. Meanwhile, drought deepened from Nebraska to Oklahoma, southern Iowa, and parts of northern and southern Indiana. 

In the South, drought conditions eased considerably for a large portion of South and East Texas as meaningful rainfall finally arrived after what was a hot and dry summer up until August. In fact, August was the sixth wettest August in 30+ years for Texas, according to data from WeatherTrends360. Louisiana, Arkansas, western Tennessee, and Mississippi also saw drought improvement.

This pattern of spotty precipitation in the Corn Belt, but wetter weather in the South, will continue into the first full week of September, week-ending September 10. According to forecasts from WeatherTrends360, this will be the eighth warmest and one of the driest first full weeks of August in 30+ years for the Corn Belt. Warm and dry weather will dry out soils and stress vegetation, but drier weather will favor harvest activities in fields where the crops are ready.

Warmer than normal temperatures, especially across the northern and western Plains, will be accompanied by mainly dry conditions in the first full week of September. Cooler than normal conditions are favored in the South where precipitation continues to be more frequent.

After a very quiet August with no named storms, the tropical Atlantic is showing signs of life as we change the calendar to September. While there are no near-term threats to the United States, the Atlantic Basin will need to be monitored for any potential threats in the weeks to come.
