Tropics becoming more active

Late-summer heat will return to the East and the Far West, while a surge of cool air will briefly cover much of the nation’s mid-section. During the weekend, however, temperatures will rebound to near- or above-normal levels in the central U.S., while late-season heat will persist in the East and West. During the next 5 days, the most significant plume of moisture will stretch from southern sections of the Rockies and Plains into the Great Lakes region, resulting in 1- to 5-inch rainfall totals. In contrast, the Far West and the Mid-Atlantic States will remain mostly dry. During the weekend, a tropical wave (or potential tropical storm) could result in heavy showers and local flooding in the southern Atlantic region, especially across southern Florida.

Looking ahead, the 6- to 10-day outlook calls for the likelihood of near- to above-normal temperatures nationwide, except for cooler-than-normal conditions in northern California. The odds of late-summer heat will be greatest in the eastern U.S. Meanwhile, below-normal rainfall across most of the western half of the U.S. will contrast with wetter-than-normal weather in the Midwestern and Atlantic Coast States, as well as the Pacific Northwest.
