USDA's Joint Ag Weather Facility says in the Corn Belt, a few showers stretch from the upper Great Lakes region into Nebraska. "However, most of the Midwest continues to experience unfavorably hot, dry weather," USDA continues. In Iowa, Missouri, North Dakota, and Wisconsin, 20% to 30% of both the corn and soybeans were rated in very poor to poor condition on Sept. 8, USDA details.
In the West, USDA reports generous monsoon rains continue to ease drought but cause local flash flooding in the Four Corners states. "In contrast, hot, dry weather prevails in northern California, where several new wildfires are burning," USDA adds. Hot, dry conditions also cover the Northwest, where Washington led the nation with 20% of its intended winter wheat acreage planted by Sept. 8, USDA explains.
On the Plains, USDA says very warm, mostly dry weather prevails, except for a few showers in Nebraska and South Dakota. "By Sept. 8, winter wheat planting was underway in all of the Plains’ major production states, with progress ranging from 2% to 13% complete," USDA details. However, soil moisture shortages remain a concern in several areas, including the central and southern High Plains, according to USDA.
In the South, USDA reports isolated showers are confined to southern Florida and the western Gulf Coast region. "Elsewhere, very warm, mostly dry weather is promoting summer crop maturation and harvesting," USDA adds. Dry weather remains favorable in the previously waterlogged Southeast, where cotton bolls were 13% to 35% open on Sept. 8, according to USDA.
In its outlook, USDA says a late-season heat wave will continue through mid-week across the Midwest. "During the second half of the week, markedly cooler air will arrive in most areas east of the Rockies—although heat will linger across the Deep South," USDA reports. Hot conditions will also persist in northern California, the northern High Plains, and the Northwest, USDA continues. Meanwhile, USDA says a late-season monsoon surge will maintain the threat of flooding in the Southwest, particularly in the southern Rockies. "Heavy rain will also spill onto the central High Plains," USDA adds. Five-day rainfall totals could reach 2 to 5 inches in the central and southern Rockies and the central High Plains, while 1- to 3-inch amounts may occur in the Northeast and southern sections of Florida and Texas, USDA elaborates. "Only light showers will occur, however, in the Midwest," according to USDA.
