Additional periodic heat wave conditions ahead for the Heartland
During the next several days, a sprawling ridge of high pressure will result in mostly dry weather and significantly elevated temperatures across large sections of the country.
Weekend high temperatures of 100°F or greater will be common across the Plains, with triple-digit heat briefly returning early next week in parts of the Midwest.
By the middle of next week, the core area of extreme heat will shift southward, with 100-degree readings expected from Texas to the southern Atlantic States, extending as far north as the Ohio Valley. In contrast, relatively cool weather will prevail during the next several days in New England and the Northwest.
Significant precipitation should be confined to the periphery of the high-pressure ridge, with 5-day totals exceeding 2 inches mostly limited to scattered locations in northern New England, southern Florida, the Four Corners States, and the Northwest.
