In the West, showers and thunderstorms are mostly confined to the Four Corners region. Elsewhere, late-season warmth and dry conditions are promoting crop maturation and fieldwork, including initial Northwestern winter wheat planting efforts.
On the Plains, dry weather favors fieldwork, including spring wheat harvesting in Montana and North Dakota. However, excessively dry conditions are delaying winter wheat planting preparations on the drought-devastated southern Plains. In addition, wildfires remain a threat in the drought-affected areas of the south-central U.S.
In the Corn Belt, cool weather and scattered showers linger in the Ohio and middle Mississippi Valleys. In contrast, warm, dry weather across the upper Midwest favors corn and soybean maturation.
In the South, dry weather and near- to below-normal temperatures are promoting summer crop maturation and fieldwork, including corn and rice harvesting.
Outlook: Hurricane Katia will pass well east of the New England coast today, while Tropical Storm Nate—over the southern Gulf of Mexico—should begin to turn westward and make a Mexican landfall during the weekend. The remnants of Tropical Storm Lee will generate a few more heavy showers in the northern Mid-Atlantic region, but widespread flooding will persist through the weekend along the Susquehanna River and several neighboring river basins. Elsewhere, significant rainfall during the next 5 days will be confined to Florida’s peninsula and the Four Corners States, although a few showers will linger across the central and eastern Corn Belt. Meanwhile, warmth across the northern U.S. will gradually expand to cover most of the remainder of the nation by early next week. The NWS 6- to 10-day outlook for September 14-18 calls for near- to above-normal temperatures nationwide, except for cooler-than-normal weather in an area centered on the Ohio Valley and the lower Great Lakes region. Meanwhile, near- to below-normal rainfall across the majority of the U.S. will contrast with wetter-than-normal conditions in the East and the Four Corners region.
