Weather
A warm pattern from the Plains, eastward
High pressure will maintain dry, increasingly warm weather across the eastern third of the nation, though locally heavy showers and thunderstorms will persist along and south of a stalled frontal boundary in the Southeast. Meanwhile, an upper-air disturbance will produce locally heavy downpours in the Corn Belt and central Great Lakes. Heat will prevail over the Plains, with highs approaching or topping 100° in areas devoid of cloud cover. Monsoon showers will linger across the Four Corners Region, while showers associated with a slow-moving cold front will overspread the Pacific Northwest. By early next week, Tropical Storm Erika — if it survives wind shear and the mountains of the Dominican Republic — may pose a threat to the Southeast and southern Mid-Atlantic States.
Looking ahead, the 6- to 10-day outlook calls for unseasonable warmth from the Plains to the Atlantic Seaboard to contrast with cooler-than-normal weather west of the Rockies. Above-normal rainfall is expected from the Pacific Northwest into the upper Midwest as well as the coastal Southeast, while drier-than-normal conditions prevail in New England and the south-central U.S.
