A major weather pattern shift ahead for the Heartland
Much of the country will slip into a dry weather pattern, although lingering showers and thunderstorms across the South and East could result in additional totals of 1 to 3 inches in a few spots. Meanwhile, completely dry weather will prevail during the next 5 days across much of the West and the northern and central Plains.
The primary temperature highlight will be intensifying Western heat, which could lead to some of the highest September temperatures on record.
In contrast, a series of cold fronts will deliver below-normal temperatures to large sections of the Plains, Midwest, and mid-South.
During the weekend, however, a brief heat surge may affect portions of the Plains in advance of an unusually strong cold front.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of below-normal temperatures between the Rockies and Appalachians, while warmer-than-normal weather will prevail in the Far West and along the Atlantic Seaboard.
Meanwhile, near- or below-normal precipitation along and west of a line from the southern High Plains to the upper Midwest should contrast with wetter-than-normal conditions across much of the eastern half of the U.S.
