The Weather Front On-Line
Across the Corn Belt, favorably dry weather prevails in the upper Midwest, where localized lowland flooding persists. Meanwhile in the previously dry eastern Corn Belt, recent showers slowed harvest activities but boosted soil moisture in advance of the winter wheat planting and establishment season.
An impressive, late-season surge of monsoon moisture will continue to interact with disturbances crossing the northern half of the U.S. Mid-week rainfall could total 1 to 2 inches, with locally higher amounts, in the Four Corners States. Mid- to late-week totals of 2 to 4 inches or more may cause flooding in portions of the upper Midwest and the Great Lakes region.
On the Plains, wet weather is returning to western and central Montana. Elsewhere across the nation’s midsection, warm, dry weather is promoting winter wheat planting and summer crop maturation and harvesting. On September 18, freezes ended the growing season—roughly on schedule—in the northeastern corner of Montana and approximately the western half of North Dakota.
For the remainder of the week, showers and thunderstorms will spread from the Midwest to the Northeast. Significant rain will be mostly confined to the western Gulf Coast region and the Northwest, although scattered showers will affect the nation’s northern tier.
Cooler conditions continued over much of the state last week. With small amounts of precipitation across the state, many farmers were able to take full advantage of the favorable weather. Many producers are either harvesting or preparing for harvest. Other farming activities include fall tillage and planting winter wheat.
Across the Corn Belt, the corn harvest is underway in southern Corn Belt States such as Missouri (16% complete) and Illinois (7% complete). However, rain will be needed soon in the Ohio Valley for the upcoming winter wheat establishment season.
Above average rainfall returned to the state last week, with the vast majority of it coming in one rainfall which was heavier in the central part of the state. This led to a temporary slowdown of the early harvests, but producers were able to get back into the fields relatively quickly. Soybeans benefited most from the rainfall.
