USDA's Joint Ag Weather Facility says in the Corn Belt, showers and thunderstorms are maintaining generally adequate to locally excessive soil moisture for summer crops. However, the rain is also slowing late-season soybean planting efforts, USDA adds. In Missouri, 16% of the soybeans had not yet been planted by June 23, along with 15% in Wisconsin and 10% in Iowa, according to USDA.
In the West, USDA says cool weather prevails. Especially cool conditions prevail in the Northwest, where widespread showers are slowing fieldwork but benefiting pastures a nd small grains, USDA details. "The wildfire threat is starting to diminish in the Southwest, although several large fires remain active," USDA explains. The West Fork Complex (near Pagosa Springs, CO ) and the Silver Fire (near Kingston, NM ) have each charred about 80,000 acres of vegetation, USDA details.
On the Plains, USDA reports scattered showers and thunderstorms are confined to the northern and eastern fringes of the region. "Cooler air is overspreading Montana, but hot weather covers the remainder of the nation’s mid-section," USDA reports. The heat is promoting winter wheat maturation and harvesting, but stressing summer crops—especially on the drought-affected central and southern High Plains, according to USDA.
In the South, USDA says lingering showers are mostly confined to the southern Atlantic states. Elsewhere, warm, humid weather is promoting a rapid crop development pace, USDA adds.
In its outlook, USDA says during the next several days, the West will experience a rapid warming trend. "Meanwhile, a hot weather pattern from the Plains to the East Coast will be replaced by cooler conditions toward week’s end, especially in the Midwest," USDA reports. During the temperature transition, USDA details widespread showers and thunderstorms will affect the eastern one-third of the U.S., with five-day rainfall totals reaching 1 to 2 inches in the Southeast and 2 to 5 inches from the lower Great Lakes region into New England. "In contrast, little or no rain will fall through week’s end from southern California to the Plains," USDA continues.
