Weather
A wet pattern for much of the Heartland
A significant risk of severe thunderstorm activity exists later Tuesday on the Plains from Nebraska to Texas. By Wednesday, the severe weather threat will shift eastward into the middle and lower Mississippi Valley. A new storm system will develop across the south-central U.S. late in the week, leading to additional severe weather and heavy rain. Five-day rainfall totals from the two storms could reach 4 to 8 inches in parts of the mid-South, including the Ark-La-Tex region; 2 to 4 inches from the central Plains into the lower Ohio and middle Mississippi Valleys; and 1 to 2 inches in the Mid-Atlantic region, the central Rockies, and the Intermountain West. Some of the Western precipitation will fall as heavy, wet snow. Cool air will continue to encroach from the northern and western U.S., leaving only a small area of mid- to late-week warmth across the South. Late in the week, however, warmth will return to the Far West.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures in the Far West, lower Southeast, and across the nation’s northern tier as far east as northern Minnesota. In contrast, cooler-than- normal conditions will dominate the mid-South, Midwest, Northeast, and central and southern sections of the Rockies and Plains. Meanwhile, near- to above-normal precipitation can be expected across most of the U.S., but drier-than-normal weather should stretch from the Pacific Northwest to the upper Great Lakes region.
