In the Corn Belt, USDA says corn and soybean planting activities, as well as summer crop emergence and growth continue in many areas under a warm, dry regime. “However, locally heavy showers are spreading across the middle Mississippi Valley and developing in the westernmost Corn Belt,” USDA continues.
On the Plains, USDA reports widespread showers and thunderstorms from Nebraska northward are slowing fieldwork but generally benefiting winter grains and summer crops. “On May 13, prior to the recent and ongoing rainfall, North Dakota’s topsoil moisture was rated 47% very short to short,” USDA details. Meanwhile, widely scattered showers dot the southern Plains, where more sustained rainfall is needed to ease the effects of a punishing drought, according to the department.
In the West, USDA reports scattered showers linger across the northern half of the region, accompanied by cool conditions. “In contrast, dry, breezy weather is leading to an elevated risk of wildfires in the Southwest, particularly across the drought-affected southern Rockies,” USDA reports.
In the South, USDA says warm, humid weather persists. “Southeastern showers have become less widespread, but remain locally heavy,” USDA adds. Currently, some of the heaviest rain is falling in the southern Mid-Atlantic region, where pockets of flash flooding and river flooding are occurring, it continues.
Heavy eastern showers will continue into the weekend but will subside thereafter, although river flooding in the Mid-Atlantic region may persist into next week. “Meanwhile, a very active weather pattern will prevail during the next several days across the nation’s mid-section, including the Plains and Midwest,” USDA reports. Five-day rainfall totals could reach 2 to 4 inches on the central Plains and 1 to 3 inches across the lower Midwest, USDA continues. “Showery weather will also cover the Northwest, but dry conditions will prevail in southern California and the Desert Southwest,” USDA explains. During the weekend, USDA reports a surge of cool air will cover the Plains and Midwest, leading to the possibility of weekend frost from the northern Plains into the upper Great Lakes region.
