USDA's Joint Ag Weather Facility says in the Corn Belt, very warm weather continues to promote an acceleration of fieldwork, including corn planting. "However, a few showers and thunderstorms are starting to develop along a west-to-east oriented axis stretching from South Dakota to northern Ohio," USDA reports. In the western Corn Belt, Tuesday’s brief surge of extreme heat resulted in record highs for May in locations such as Tekamah, Nebraska (108°F), and Sioux City, Iowa (106°F), USDA details.
In the West, USDA says generally warm, dry weather continues to favor fieldwork and rapid crop development. However, cooler air is spreading inland across the Pacific Northwest, USDA adds.
On the Plains, USDA says a few showers are developing, mainly in parts of South Dakota and Texas. "However, the region's sudden turn toward very warm weather is allowing for an increase in fieldwork," USDA explains. On the central and southern High Plains, hot weather is another blow to winter wheat already hit hard by freezes and drought, according to USDA.
In the South, a few showers and thunderstorms are developing across southern and eastern Texas, USDA reports. Across the remainder of the region, dry weather favors spring fiel dwork, including previously delayed cotton, rice, and soybean planting operations, USDA elaborates.
In its outlook, USDA says warm weather will cover much of the U.S. during the next several days. "Late-week warmth will be especially notable across the High Plains," USDA adds. Toward week’s end, however, cooler air will arrive in the West, USDA continues. "By early next week, cooler weather will overspread the Plains. Meanwhile, a more active weather pattern—featuring locally severe thunderstorms—will develop across the Plains and Midwest," USDA explains. Five-day rainfall totals could reach 1 to 2 inches or more across the upper Midwest, USDA reports. In contrast, little or no rain will fall from central and southern California to the southern High Plains, USDA details.
