USDA's Joint Ag Weather Facility says on the Plains, a new surge of cold air is arriving. "Rain and snow showers accompany and trail the cold front, which is crossing the central Plains," USDA reports. Pastures and recently planted winter grains in Montana are benefiting from last week's precipitation, but extremely dry conditions persist across the remainder of the northern Plains, according to USDA.
In the West, USDA says warm weather has returned to the interior Northwest and continues across the remainder of the region. "Fieldwork, including harvest activities for rice in California and cotton in Arizona, is proceeding," USDA reports. However, very dry conditions in the Northwest remain a concern with respect to the germination and establishment of rain-fed winter wheat, USDA explains.
In the Corn Belt, cold weather is returning to the upper Midwest, accompanied by a few rain showers, according to USDA. "In recent days, corn and soybean harvest activities have continued to advance at a record-setting pace in the upper Midwest, but fieldwork has been slowed by cool, damp conditions in the Ohio Valley," USDA explains.
In the South, USDA says cool but dry weather favors a return to fieldwork, following last week's significant rainfall.
In its outlook, USDA says as the week progresses, cool air will begin to recede. "As a result, late-week weather patterns will feature chilly conditions mostly confined to areas from the northern Plains into the Northeast," USDA explains. By the weekend, temperatures will be above normal in nearly all areas from the Plains to the East Coast, USDA explains. Meanwhile, a fairly tranquil weather regime will become more active late in the week, USDA reports. By Thursday, showers will develop across the Southwest, USDA adds. "Toward week’s end, precipitation will become more widespread across the Central and Southern Plains and the Midwest," USDA reports. Late-week rainfall could become heavy in the Great Lakes region, it continues. "Elsewhere, much-needed precipitation will also overspread the Pacific Northwest, starting on Friday," according to USDA.
