USDA's Joint Ag Weather Facility says in the Corn Belt, showers stretch from the Bootheel of Missouri into Michigan. During the last several days, excessive rain has caused some lowland flooding from southeastern Missouri into southern Indiana, while showers have eased drought and benefited immature summer crops in the lower Great Lakes region. Farther west, scattered thundershowers are affecting the western Corn Belt, where growing conditions are favorable, USDA notes.
In the South, a plume of tropical moisture extends northeastward from the western Gulf Coast region, maintaining the threat of heavy showers. Meanwhile, most of Louisiana’s flood-stricken areas are experiencing warm and humid but dry weather, allowing recovery efforts to continue in areas where water has receded, USDA reports.
On the Plains, USDA says very warm, mostly dry weather favors fieldwork and crop development. On August 14, the spring wheat harvest was ahead of the five-year average pace in all major production states, ranging from 37% complete in Montana to 84% complete in South Dakota.
In the West, USDA reports hot, mostly dry weather favors northwestern small grain harvesting and other late-summer fieldwork. Isolated showers are confined to the Four Corners States, USDA states.
In its outlook, USDA says a very active weather pattern will continue for the remainder of the week due to the interaction between cold fronts and tropical moisture. In fact, rain can be expected nearly everywhere during the next five days except in the Far West, where hot, dry weather will persist. Five-day totals could reach 1 to 3 inches, with locally higher amounts, in many locations, although the focus for heaviest rain will shift northwestward into parts of the Plains and upper Midwest as the week progresses. By week’s end, cool conditions will become established across the nation’s mid-section, including the Plains and upper Midwest, while heat will persist in the Far West and the Eastern States, USDA states.
