Weather
Heat, humidity to dominate much of the Heartland
During the next several days, moisture embedded within the Southwestern monsoon circulation will continue to interact with cold fronts crossing the North. Some of the heaviest rain should occur across the northern Corn Belt, resulting in local flooding and 5-day totals that could reach 2 to 4 inches. Occasional showers on the northern Plains could provide limited drought relief. At the same time, a strong ridge of high pressure will result in hot, humid, mostly dry conditions across a broad area stretching from the southern Plains into the Mid-Atlantic States. Elsewhere, locally heavy showers will continue in the Southwest, while dry weather will accompany building heat in California and the Northwest.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of above-normal temperatures from the Pacific Coast to the Plains, except for cooler-than-normal conditions in parts of the Southwest. Elsewhere, near- to below-normal temperatures will cover most areas from the Mississippi Valley eastward, with lingering heat confined to the lower Southeast. Meanwhile, near- to above-normal rainfall can be expected in the southern half of the U.S., while drier-than-normal conditions should occur throughout the North.
