USDA's Joint Ag Weather Facility says in the Corn Belt, cool, showery weather prevails in the vicinity of the Great Lakes, especially in parts of Michigan and Wisconsin. "In the southern Corn Belt, warm, dry weather favors a rapid corn and soybean development pace, as well as late-season planting efforts," USDA continues.
In the West, USDA reports cooler conditions have replaced last week’s h eat wave. "Weekend showers provided beneficial moisture in some areas, but more rain would be welcomed for rangeland, pastures, and spring-sown small grains. A few wildfires have flared in parts of Arizona and the Northwest," USDA elaborates.
On the Plains, USDA reports locally heavy showers and thunderstorms are developing in conjunction with an approaching low-pressure system. "Cooler air is replacing weekend heat across the northern Plains, but hot weather continues farther south," according to USDA. Today’s high temperatures could reach 100°F on the southern High Plains, it elaborates.
In the South, USDA explains showers and thunderstorms stretch from eastern Texas to the central Gulf Coast. "Elsewhere, warm, dry weather is promoting crop growth and fieldwork, including late-season cotton, peanut, and soybean planting," USDA details.
In its outlook, USDA says a storm system currently developing over the nation’s mid-section will drift eastward. As a result, heavy showers and locally severe thunderstorms will gradually spread from the Plains into the Midwestern and Mid-Atlantic States, USDA continues. "Five-day rainfall totals could reach 1 to 3 inches along and near the path of the storm," USDA elaborates. Locally heavy showers will also develop in the eastern Gulf Coast region, while little or no rain will fall in California and the Southwest, USDA reports. Elsewhere, scattered Northwestern showers could produce local totals in excess of an inch, USDA adds. "Generally cool conditions in the West will contrast with an early-season heat wave across the central U.S.," according to USDA.
