USDA's Joint Ag Weather Facility says in the Corn Belt, cool, dry weather prevails, except for some showers in the west. "Topsoil moisture remains limited across the southern and eastern Corn Belt; on June 10, topsoil moisture rated very short to short was greater than 50% in Missouri (87%), Illinois (78%), Indiana (74%), Nebraska (71%), Iowa (66%), Wisconsin (56%), and Ohio (56%)," USDA reports.
In the West, USDA explains cool, showery weather is returning to areas from the Pacific Northwest to the northern Rockies. "Elsewhere, warm, dry weather is promoting fieldwork and crop development, although breezy conditions are maintaining the threat of wildfire development and expansion in parts of the Intermountain West," USDA explains.
On the Plains, USDA says beneficial rain lingers across southern areas, while isolated showers and thunderstorms are developing farther north. "However, agricultural drought persists on the central Plains, where topsoil moisture was rated at least three-quarters very short to short on June 10 in Kansas (76%) and Colorado (75%)," according to USDA.
In the South, USDA explains spotty showers linger from Texas to the southern Atlantic Coast. "Despite early-week showers, more rain is needed across the drought-affected Mid-South, where corn is beginning to enter reproduction," USDA adds. By June 10, one-fifth (20%) of the corn was silking in Tennessee, compared to the five-year average of 2%, according to USDA.
In its outlook, USDA says high pressure building south out of eastern Canada will maintain mostly dry weather across the eastern third of the nation. "Showers are likely on the periphery of the high, especially along the Gulf Coast and across the western and northern Corn Belt, where locally heavy rain could fall," USDA explains. A few showers may also dot the Great Plains, particularly in northern locales, USDA reports. "Generally dry weather is expected from the Rockies to the Pacific Coast," USDA adds.
