USDA's Joint Ag Weather Facility says on the Plains, hot weather prevails, with today’s high temperatures expected to again reach or exceed 100°F as far north as western Nebraska. "Widely scattered showers are confined to the northern half of the region; hot, dry weather on the southern High Plains remains a concern with respect to the conditions of rangeland, pastures and immature summer crops, as well as soil moisture depletion in advance of winter wheat planting," USDA explains.
In the West, USDA says hot weather persists in most areas, but cooler air is beginning to push inland across the Pacific Coast. "Widespread showers in the Northwest are slowing fieldwork but aiding wildfire containment efforts and boosting soil moisture in preparation for winter wheat planting," USDA reports.
In the Corn Belt, USDA says isolated showers are confined to western corn and soybean production areas. "Overnight rainfall aided a few immature summer crops, primarily in the middle Missouri Valley," USDA explains. Elsewhere, cool weather in the lower Great Lakes region contrasts with building heat across the upper Midwest, USDA continues.
In the South, shower activity is mostly confined to southern Florida, according to USDA. Elsewhere, warm, dry weather favors summer crop maturation and harvesting, although drought persists in the western Gulf Coast region and is returning to parts of the lower Mississippi Valley, according to USDA.
In its outlook, USDA says late-season heat will continue to dominate the nation’s mid-section into next week. "The core area of heat will affect the northern and central Plains and the upper Midwest, where temperatures should average 10 to 20°F above normal during the next five days," USDA reports. In contrast, USDA continues, the passage of a pair of cold fronts will result in cool conditions from the lower Great Lakes states into the Northeast. "Cooler air will also briefly spread inland across the Pacific Northwest," USDA adds. Meanwhile, five-day rainfall totals could locally reach 1 to 3 inches from the Pacific Northwest to the northern High Plains, according to USDA. "Totals of 1 to 2 inches will be possible in the Southwest, Florida, and coastal Texas, but only light showers can be expected in the Midwest," USDA elaborates. Dry weather will continue across the southern Plains, USDA reports.
