Favorable harvest weather for much of the Heartland
Warmth will continue to spread eastward, reaching into areas of the South, East, and lower Midwest that have been experiencing cool weather. Late in the week, however, a new surge of cool air will affect parts of the Midwest and Northeast.
Meanwhile, unusual warmth will persist in much of the West, with record-setting high temperatures extending as far east as the Plains. By week’s end, cooler air will finally arrive along the Pacific Coast, signaling a pattern change.
During the next 5 days, most of the country will remain dry. By Friday, however, much-needed precipitation may begin to spread inland across northern California and the Pacific Northwest. Elsewhere, a few showers may graze the Great Lakes and Northeastern States, while the tropics will remain active.
While Tropical Storm Gamma does not pose a significant threat to the United States, a trailing system (Tropical Depression Twenty-Six) should have the opportunity to strengthen and could reach the U.S. Gulf Coast as a hurricane by Friday.
Looking ahead, the 6- to 10-day outlook calls for warmer-than-normal weather nationwide, except for near- or below-normal temperatures in northern and central California, the Great Basin, and the Northwest.
Meanwhile, wetter-than-normal conditions in the Southeast and Northwest should contrast with near- or below-normal precipitation across the remainder of the country. The greatest likelihood of drier-than-normal weather will cover New England and central and southern sections of the Rockies and Plains.
