Across the Corn Belt, most corn and soybean harvest activities are proceeding under a cool, dry weather regime. However, light rain is overspreading westernmost production areas, including eastern Nebraska.
On the Plains, a chilly rain is falling across central areas, particularly across Nebraska. Meanwhile on the southern Plains, a final day of unusually warm, breezy weather is reducing soil moisture for winter wheat establishment. Monday’s high temperatures will top 90°F in parts of central, west-central, and southern Texas.
In the South, locally heavy showers associated with a low-pressure system over the southern Gulf of Mexico are spreading across southern Florida. Elsewhere, very warm, dry weather favors fieldwork, including summer crop harvesting and winter wheat planting.
In the West, rain and snow showers are affecting the central Rockies. Elsewhere, a late-season spell of warm, dry weather is underway, promoting fieldwork and Northwestern winter wheat development.
The interaction between a storm crossing the nation’s mid-section and a potential tropical system over the Gulf of Mexico will result in a period of wet weather across the eastern one-third of the U.S.
For the remainder of the week, precipitation totals could reach 1 to 3 inches from the Mid-South into the Northeast. Rainfall amounts in the Atlantic Coast States will depend upon the degree of tropical involvement, although parts of Florida’s peninsula may receive more than 5 inches of rain regardless of whether or not a tropical storm forms.
In the wake of the Eastern storminess, the coldest air of the season will overspread many areas from the Plains to the East Coast. Late-week freezes should be expected as far south as the central Plains and the Mid-South. In contrast, warm, dry weather will cover much of the West through week’s end.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures in the West and northern New England, while cooler-than-normal weather will prevail from the central and eastern Gulf Coast States into the Ohio Valley and Mid-Atlantic States. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal conditions in the Pacific Northwest, the lower Great Lakes region, and much of the Northeast.
