Across the Corn Belt, rain is confined to the Ohio Valley and the lower Great Lakes region, where final corn harvesting efforts have once again stalled. Elsewhere in the Midwest, mild, dry weather prevails.
On the Plains, dry weather prevails. Mild conditions are promoting some late-season winter wheat development as far north as the central High Plains, where Monday’s high temperatures will approach 70°.
In the South, widespread rain is slowing late-season fieldwork, although warm, dry weather lingers along the Atlantic Seaboard. In contrast, sharply cold air is overspreading areas from the Delta westward. Monday morning’s temperatures range from below 32° in much of eastern Texas to near 70° in the southern Atlantic region.
In the West, patches of light rain and snow stretch from northern California and southern Oregon into the northern Rockies. Elsewhere, mild, dry weather is promoting late-autumn fieldwork, including the final stages of cotton harvesting in California and the Desert Southwest.
For the remainder of Monday, an early-season snowfall can be expected in parts of the Southeast, including northeastern Arkansas, western Tennessee, and northern portions of Alabama and Mississippi. Meanwhile, heavy rain (1 to 2 inches or more) will fall in the eastern Corn Belt and from the southern Appalachians to the southern Atlantic Coast.
By Tuesday, snow will develop from Indiana into northwestern Ohio and southeastern Michigan, while heavy rain will spread into the Mid-Atlantic States. Precipitation will end by mid-week in the East, but snow will overspread northern portions of the Rockies and Plains.
During the second half of the week, sharply colder air will arrive in the western and central U.S., while rain and snow showers will develop from the Four Corners States to the southern Plains.
Looking ahead, the 6- to 10-day outlook calls for colder-than-normal weather nationwide, except for near- to above-normal temperatures from the upper Midwest into the Northeast. Meanwhile, drier-than-normal conditions across the majority of the U.S. will contrast with above-normal precipitation in southern Texas and from the northern Plains into the Great Lakes region.
