USDA's Joint Ag Weather Facility says in the Corn Belt, significant precipitation is confined to the Ohio Valley, although isolated showers dot areas west of the Mississippi River. "By June 16, more than one-fifth of the soybeans had not yet been sown in Missouri (70% planted), Wisconsin (72%), and Iowa (77%)," USDA elaborates.
In the West, USDA reports beneficial showers are developing across the interior Northwest, where crop conditions have been declining in recent weeks. "On June 16, more than one-third (34%) of Oregon’s winter wheat was rated very poor to poor, while nearly one-quarter (24%) of Washington’s spring wheat was rated very poor to poor," USDA details. Meanwhile, cooler air is overspreading California, but hot weather persists in parts of the Southwest, according to USDA.
On the Plains, USDA says thundershowers are providing some additional drought relief across central and southern areas. "However, the storms have also resulted in local wind and hail damage on the central and southern High Plains," USDA continues. Meanwhile on the northern High Plains, warm, dry weather is promoting late-season planting efforts, USDA reports.
In the South, USDA says widespread showers and thunderstorms extend from Texas to the central and southern Appalachians, slowing fieldwork but maintaining abundant moisture reserves for pastures and summer crops.
In its outlook, USDA says for the remainder of today, a low-pressure system crossing the Appalachians will remain the focus for showers and thunderstorms in the Southeast, where rainfall could total 1 to 2 inches. "Meanwhile, a developing storm over the Northwest will contribute to a gradual increase in shower activity—with 1- to 2-inch totals—across the nation’s northern tier as far east as the upper Midwest," USDA details. In contrast, USDA continues, little or no rain will fall during the next five days in California, the Southwest and the Mid-South. Elsewhere, late-week heat across the Plains will spread into the Midwest and Northeast during the weekend, according to USDA.
