As we head into the Labor Day weekend, expect some dramatic weather changes. Midwest will see strong storms rolling in, moving toward the Mid-Atlantic and Southeast with heavy rain. Utah might experience heavy rain due to a moving front. While the West Coast and Northeast enjoy cooler temperatures, the Heartland is set for more heat with temperatures feeling like 105 to 110 degrees. Let's dive into the details for each region.

Storms Moving South

Midwest to Southeast: Over the Labor Day weekend, thunderstorms could be severe from the Midwest across the Ohio Valley, and into the Mid-Atlantic and Southeast. Watch out for heavy rain and a slight chance of flash flooding, especially near the Mid-Atlantic coast this afternoon into Sunday.

Rain on the Horizon

Western U.S.: A front moving through might cause heavy rain in Utah on Sunday. The rain can be intense, especially in urban areas and where the ground is prone to flooding, like dry washes and burn scars.

Heat and Cool Balance

Midsection of the Country: The Nation's Heartland will continue to experience oppressive heat with heat indices up to 110 degrees. Temperatures will remain high during the day and night.

Showers and Thunderstorms

Northwestern U.S.: A deep upper low brings showers and storms as it moves inland. Temperatures here will be 10 to 20 degrees cooler than normal, with freezing conditions at higher elevations.
