USDA's Joint Ag Weather Facility says in the Corn Belt, sunny skies are promoting crop development following recent moderate to heavy rainfall. "Nationally, corn and soybeans were rated 75% and 72% good to excellent, respectively, on June 26," USDA elaborates.
In the West, USDA says hot, mostly sunny weather is maintaining high irrigation requirements but promoting fieldwork, though several large wildfires remain uncontained in southern California and the Southwest. "Monsoon showers have increased, however, over the Four Corners and Southwest," USDA reports.
On the Plains, USDA explains heat has generally abated and is now mostly confined to the central and northern High Plains. "Winter wheat harvesting was progressing rapidly (nationally at 45%, versus 33% last year) under mostly sunny skies, though morning showers are slowing fieldwork in portions of Colorado and Kansas," USDA details.
In the South, USDA reports scattered showers and thunderstorms are providing localized soil moisture improvement. "Moderate to severe drought persists, however, from the eastern Delta into the southern Appalachians," USDA continues.
In its outlook, USDA says a weak cold front will maintain showers and thunderstorms from the central Gulf Coast to the Atlantic Seaboard. "Meanwhile, a steady influx of moisture — from the Gulf and partially associated with the Southwest Monsoon — will combine with a series of slow-moving disturbances to produce a swath of moderate to heavy rain (1 to 5 inches, locally more) from the central High Plains into the middle Mississippi Valley," USDA reports. Somewhat lighter showers will spread over the western and northern Corn Belt as well as the Ohio Valley, USDA continues. Out West, USDA reports monsoon showers will continue in the Four Corners Region, occasionally reaching into the central and northern Rockies. "Seasonably dry albeit hot weather is expected west of the Rockies," it explains.
