Across the Corn Belt, a sharp cold front extends from Lake Michigan into northwestern Missouri. East of the front, record-setting warmth continues to promote corn and soybean harvesting. Farther west, however, cold weather accompanies a quick, post-frontal transition from rain to freezing rain and snow. Early Tuesday, accumulating snow is falling in parts of Nebraska and portions of neighboring states. By November 8, however, the soybean harvest was complete in Nebraska and North Dakota—and more than 95% complete in Illinois, Iowa, Minnesota, South Dakota, and Wisconsin.
On the Plains, weather conditions in Montana have improved, following recent snowfall, although Tuesday morning’s minimum temperatures fell below 10° in some locations. Currently, snow has moved into Nebraska and portions of surrounding states, while lingering warmth is confined to eastern sections of Oklahoma and Texas. Despite recent and ongoing precipitation, more than one-fifth of the winter wheat was rated in very poor to poor condition on November 8 in Colorado (28% very poor to poor), Texas (27%), Kansas (23%), and Nebraska (21%).
In the South, Tropical Storm Eta has drifted to a position just north of the western tip of Cuba, with diminishing wind- and rainfall-related impacts in Florida. Still, November 5-9 rainfall totaled 6 to 12 inches or more in many locations across southern Florida, causing local flooding and halting vegetable planting preparations, as well as citrus and sugarcane harvesting. Elsewhere in the South, warm, dry weather favors harvesting of crops such as cotton, peanuts, and soybeans.
In the West, cold, mostly dry weather prevails. Early Tuesday, scattered rain and snow showers are confined to the northern Rockies and Pacific Northwest. Recent precipitation provided some relief from dry conditions, but more storminess will be needed for further recovery due to the extent and severity of the Western drought.
Tropical Storm Eta will continue to lurk over the eastern Gulf of Mexico, but additional U.S. impacts are not expected to be significant as the cyclone will soon encounter more hostile atmospheric conditions. Nevertheless, additional rainfall across Florida could total 1 to 2 inches. Meanwhile, the mid-week interaction between tropical moisture and a strong cold front will result in heavy rain (2 to 4 inches) from the central and southern Appalachians to the middle Atlantic Coast. Farther west, snow will spread northeastward from Nebraska, ending Tuesday night across the upper Great Lakes region. Late in the week, stormy weather will return across the Northwest, while scattered showers will develop in the eastern half of the U.S.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of above-normal temperatures across most of the country, while cooler-than-normal conditions will be confined to northern California and the Northwest. Meanwhile, above-normal precipitation in much of the West and Northeast should contrast with drier-than-normal weather in the southern Rockies and from the Plains and Mississippi Valley into the Southeast.
