Hot weather that has been affecting much of the central U.S. will retreat southward. However, during the weekend and early next week, Southern heat will expand and intensify, stretching from the Desert Southwest to the southern Atlantic Coast. Triple-digit heat (high temperatures of 100°F or greater) will develop in the Desert Southwest and return by Sunday and Monday across parts of Texas and eastern New Mexico.
Mostly dry weather will accompany the heat, with little or no rain expected during the next 5 days from California to Texas. In contrast, generally cool weather and periodic showers will stretch from the Pacific Northwest into the upper Midwest.
Elsewhere, a low-pressure system over the western Atlantic Ocean will drift southwestward, with late-week showers and breezy conditions expected in the southern Atlantic States.
