USDA's Joint Ag Weather Facility says in the Corn Belt, sunny skies, with only a slight chance of thunderstorms, is promoting corn and soybean development in the Mississippi Valley. "However, locally heavy rain and thunderstorms continue in the Ohio Valley, hampering soft red winter wheat harvesting and sustaining flood warnings while keeping summer crops abundantly watered," USDA explains.
In the West, USDA says a heat wave continues from California to the Northwest. "Showers and thunderstorms are scattered throughout the Southwest and northern Rockies, though a risk of wildfire activity exists in the Great Basin," according to USDA.
On the Plains, USDA says warm, mostly dry weather continues from Nebraska to Texas but chances for isolated showers and thunderstorms will increase throughout the day in western areas. "Meanwhile, rain has begun to overspread Montana and the Dakotas," USDA adds.
In the South, USDA says tropical showers will continue throughout much of the day in the Southeast, and scattered showers and thunderstorms may develop this afternoon in the Delta.
In its outlook USDA says high pressure positioned off the Atlantic Coast will continue to pump tropical moisture into the East, with the highest likelihood of significant rain from the Gulf Coast northward into the Ohio Valley. "Additional rainfall of more than 2 inches is possible from southern Alabama to the central Appalachians through the weekend," USDA details. Farther west, scattered showers will continue throughout the Rocky Mountain states as the monsoon strengthens, USDA explains. "Rain will also increase along a stationary front stretching across the northern Plains and western Great Lakes," USDA continues. In contrast, dry weather will continue on the southern Plains, supporting rapid harvesting of hard red winter wheat, and heat and dryness are expected to continue in the West Coast states, fostering rapid development of cotton, rice and other irrigated crops, according to USDA.
