USDA's Joint Ag Weather Facility says in the Corn Belt, increasingly showery weather is slowing final planting efforts but boosting soil moisture for corn and soybean growth. "By June 12, topsoil moisture was rated one-quarter to one-half very short to short in Michigan (46%), Indiana (31%), Ohio (31%), and Missouri (28%)," USDA elaborates.
In the West, USDA says cool weather prevails. "In the Northwest, widespread precipitation is benefiting spring-sown small grains. Snow is accumulating in the northern Cascades at elevations above 5,000 feet," USDA reports.
On the Plains, USDA reports clusters of showers and thunderstorms are associated with a developing low-pressure system. The rain is slowing fieldwork, including winter wheat harvesting, but generally benefiting rangeland, pastures and summer crops, it explains. "Although the southern Plains’ winter wheat harvest remains behind schedule, recent dry weather had allowed Oklahoma’s harvest to jump from 5 to 34% complete during the week ending June 12," USDA details.
In the South, USDA says isolated showers and thunderstorms are heaviest across portions of the lower Mississippi Valley. "However, many areas across the interior Southeast would benefit from additional rainfall; on June 12, topsoil moisture was rated 55% very short to short in Alabama, along with 40% in Georgia and 33% in Mississippi," USDA elaborates.
In its outlook, USDA says for today, a low-pressure system currently over the northern Plains will drift east-southeastward, reaching the Mid-Atlantic states by Thursday. "The storm system will help to focus rainfall that could total 1 to 3 inches from the Dakotas to the Mid-Atlantic coast," USDA explains. Meanwhile, a separate area of showers should result in 1- to 2-inch rainfall totals in the Southeast, USDA continues. Elsewhere, dry weather will prevail from central and southern California into the Southwest, while showers will linger through week’s end in the Northwest. "Very cool weather in the Northwest will contrast with hot conditions across much of the nation’s mid-section; mid- to late-week maximum temperatures will frequently exceed 100°F as far north as the central Plains," USDA reports. Toward week’s end, heat will also return to California and the Desert Southwest, it adds.
