Across the Corn Belt, snow showers linger in the wake of a departing storm system. Breezy conditions accompany the light snow. Friday morning’s minimum temperatures plunged below 0° in eastern North Dakota, leading to very low wind-chill readings and an increase in stress on livestock.
On the Plains, cold, blustery conditions prevail across the eastern Dakotas. In contrast, mild weather is returning across the southern Plains, where snow that fell earlier in the week is starting to melt.
In the South, cold, breezy weather trails a period of heavy rain. Light snow is falling early Friday across portions of the interior Southeast, including much of Kentucky and Tennessee. Many rivers are still rising, following recent downpours. In fact, minor to moderate flooding is being reported at more than 200 Southeastern river gauges, with major flooding at about a dozen gauge sites. The Cumberland River at Pineville, Kentucky, crested on Thursday at 17.06 feet above flood stage—the second-highest level on record in that location behind 19.80 feet above flood stage on April 5, 1977.
In the West, a band of unsettled, showery weather generally stretches from Washington to Colorado. The wet weather, combined with melting of lower-elevation snowpack, is leading to elevated river levels in southeastern and western Washington, as well as northeastern Oregon. Early Friday, major flooding is occurring along the Umatilla River in northeastern Oregon. In contrast, dry weather stretches from California to the southern Rockies.
Heavy precipitation will continue through the remainder of Friday in the Northeast as a storm system moves along the northern Atlantic Coast. Interior sections of the Northeast, from the mountains of West Virginia to northern Maine, will experience heavy snow. In the storm’s wake, Southeastern flooding will persist for several days as water drains from creeks and streams to larger rivers. Meanwhile, colder, drier air will overspread the Northwest during the weekend, although flooding may linger for several days. Farther east, weekend snow will blanket portions of the northern Plains and Midwest, with some of the most substantial accumulations expected from South Dakota to Michigan. At the same time, showery weather will develop across parts of southern California and the Southwest. Early next week, locally heavy rain may return across the Southeast, possibly prolonging the flood situation.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of below-normal temperatures in northern Maine and west of a line from central Texas to Michigan. Warmer-than-normal weather will be confined to the Southeast and mid-Atlantic. Meanwhile, near- or below-normal precipitation across Florida’s peninsula and the Pacific Coast States should contrast with wetter-than-normal conditions across the remainder of the country.
