USDA's Joint Ag Weather Facility says in the Corn Belt, isolated showers are confined to the upper Mississippi Valley. "Midwestern soil moisture continues to gradually diminish, with the most acute shortages noted across Iowa (excluding the northeast), northern Missouri, and neighboring areas," USDA details. Meanwhile, cool weather lingers across the Ohio Valley, but very warm weather across the northern and western Corn Belt is promoting corn and soybean development, according to USDA.
In the West, USDA says widely scattered showers are affecting southern California, the southern Great Basin, and the Desert Southwest. "Elsewhere, hot, dry weather favors summer crop maturation and fieldwork, including Northwestern winter wheat harvesting," USDA continues. However, numerous wildfires remain active in the Northwest, USDA reports.
On the Plains, USDA says dry weather accompanies building heat. "Today’s high temperatures will approach 100°F as far north as eastern Montana and western North Dakota," USDA explains. Heat favors crop development and fieldwork, but is increasing stress on rangeland, pastures, and rain-fed summer crops, according to USDA.
In the South, USDA reports dry weather in the drought-affected western Gulf Coast region contrasts with ongoing showers in the well-watered Southeast. "Currently, some of the heaviest showers are affecting the Carolinas," USDA adds.
In its outlook, USDA says dry, hotter weather will prevail for the remainder of the week from the central and southern Plains into the Mid-South. "In contrast, heat will be slower to arrive in the Southeast, where additional rainfall could total 1 to 2 inches," USDA continues. Occasional showers in the Southwest and mid- to late-week rainfall in the upper Midwest will result in local totals in excess of an inch, according to USDA. "At the same time, most of the nation will be experiencing near- to above-normal temperatures," USDA continues. "Temperatures will remain below 95°F in most of the Corn Belt, but readings will briefly top 100°F as far north as the Dakotas," USDA details.
