While much of the country will enjoy tranquil weather on Sunday, some areas could still see scattered thunderstorms that could bring lightning, heavy rain leading to spotty flooding, and gusty winds.

Flash flood threat

There is also a potential for flash flooding in parts of the Southwest on Sunday.

This includes many national parks in Arizona and Utah on Sunday, including Grand Canyon National Park, Zion National Park and Bryce Canyon National Park, all which recently experienced significant flash flooding impacts from monsoon storms.

While the threat is not as widespread and intense as the previous event last weekend, scattered thunderstorms later in the day could bring downpours and frequent lightning. Flash flooding is possible where the heaviest rain develops.

Any burn scar areas from recent wildfires in Utah and Arizona will be especially vulnerable to any heavy rain that falls on Sunday.
