High pressure will hold over much of the Northeast and the Mid-Atlantic on Sunday, leading to a mainly dry day. Clouds and sunshine are expected for those regions. Some showers and thunderstorms are also expected especially near Lake Erie and across Maine, Vermont and New Hampshire.
A lingering front will hold over the Carolina coastline, bringing rounds of showers and thunderstorms from southern Virginia and North Carolina down to southern Georgia and much of Florida. Some of the thunderstorms may be heavy with drenching downpours.
Across the central Plains, some thunderstorms are expected to spread into Kansas, Missouri and Illinois. An afternoon storm will bring thunderstorms to parts of Colorado, Nebraska, Wyoming and the Dakotas. Some of these storms could be severe late in the day, with the potential to produce damaging wind gusts and flooding.
From west of the Rockies and to the Pacific Coast, the high heat and dry conditions will continue, keeping those regions at elevated risk for wildfires. Sunshine is forecast to push temperatures well into the triple digits.
