Across the Corn Belt, near- or below-normal temperatures continue to benefit reproductive to filling corn and soybeans, although significant developmental delays remain a concern as the end of summer approaches. By Aug. 11, more than one-fifth of the corn was not yet silking in Indiana, Michigan, Ohio, and Wisconsin.
On the Plains, temperatures have fallen to near-normal levels in Texas, accompanied by a few showers and thunderstorms. However, many rain-fed crops on the southern Plains are still in need of rain. Meanwhile, dry but unusually cool weather over the northern Plains favors small grain harvesting.
In the South, scattered showers and warm, humid conditions are maintaining generally favorable conditions for immature summer crops. Early Wednesday, some of the heaviest showers are occurring across the Deep South, in the central and eastern Gulf Coast regions.
In the West, a hot, dry weather regime is reducing topsoil moisture and increasing stress on some rangeland and pastures. However, the conditions also favor Northwestern winter and spring wheat harvesting.
A cold front interacting with a warm, humid airmass will continue to produce scattered to widespread showers and thunderstorms across the lower Southeast. Five-day rainfall totals could exceed 5 inches in parts of northern Florida. Later in the week, locally heavy showers will develop from the southern Rockies into the western Corn Belt. In the latter region, as much as 1 to 3 inches of rain may fall. Widely scattered showers will occur in other parts of the central and eastern U.S., but dry weather will prevail during the next 5 days west of the Rockies. Following a few days of cooler weather in most areas east of the Rockies, heat will expand northward during the weekend. Elsewhere, hot weather will persist across the interior West.
Looking ahead, the 6- to 10-day outlook calls for near- or above-normal temperatures nationwide, except for cooler-than-normal conditions in along the Canadian border in Montana and North Dakota. Meanwhile, near- or above-normal rainfall in the East, North, and Far West will contrast with drier-than-normal weather across large sections of the Rockies and High Plains.
