USDA's Joint Ag Weather Facility says in the Corn Belt, cooler air is arriving. "Much-needed rain is falling in parts of the southwestern Corn Belt, generally stretching from eastern Nebraska to southern Missouri," USDA details. However, unfavorable short-term dryness persists in much of Iowa, northern Missouri, and neighboring areas, according to USDA. "On July 21, nearly one-fifth (19%) of Missouri’s corn was rated in very poor to poor condition, up from 14% last week," USDA elaborates.
In the West, USDA says isolated showers linger across California, the southern Great Basin, and the Desert Southwest. In the Northwest, however, hot, dry weather continues to promote fieldwork and crop development, USDA adds.
On the Plains, USDA reports cooler air is overspreading the northern half of the region, but hot weather prevails from Kansas to Texas. "Near the boundary between hot and cool air, beneficial showers are affecting the central Plains," USDA explains.
In the South, USDA reports favorably drier weather is arriving in the southern Atlantic states, except for lingering showers in parts of Florida. "July rainfall records have already been broken in locations such as Greenville-Spartanburg, South Carolina (13.57 inches), and Roanoke, Virginia (12.15 inches)," USDA details. In contrast, beneficial showers dot the Mid-South, where only 27% of the pastures in Arkansas were rated good to excellent on July 21, according to USDA.
In its outlook, USDA says below-normal temperatures will prevail for the remainder of the week, particularly across the northern and central Plains, Midwest and Northeast. "Late in the week, a secondary surge of cool air will arrive across the Plains and Midwest," USDA continues. In contrast, hot weather will persist for much of the week across the Northwest and Deep South, according to USDA. The week’s most impressive rain will fall due to the interaction between the monsoon circulation and a front draped across the South, USDA explains. "Five-day rainfall totals could reach 2 to 5 inches from northern Oklahoma and southern Kansas to the northern Mississippi Delta," USDA continues. "Lighter showers (locally an inch or more) will affect the East, Midwest and Southwest," USDA adds.
