It comes as higher ground in northwestern Montana is expecting to see the first snowflakes of the season, the NWS said in its public discussion for Wednesday.
This will be caused by “sharply colder air” behind the “strong cold front associated with the next low-pressure system marching across the northern Rockies.”
Meanwhile, in the mid-Atlantic, “record heat” is expected for the day, with heat lasting “a couple more days” for the Ohio and Tennessee Valleys.
The NWS said: “A cold front has brought relief to the heat across the northern Plains while triggering clusters of strong thunderstorms across the Midwest this morning.
“As the front continues to push east and southeastward, a day of record heat is expected to impact the Mid-Atlantic states where high temperature could reach 100 degrees around the nation’s capital.”

Tuesday saw extreme heat warnings in place for parts of the Midwest, with temperatures forecast to soar into the 90s.
The last few days have seen extreme weather hit different parts of the U.S., from heat waves to snowstorms to flash floods.
While millions across the Midwest struggled with a brutal heatwave, an unusually cold storm swept in from the Gulf of Alaska and hit the West Coast an early hint of winter.
Meanwhile, Three tropical cyclones hit the Pacific Ocean on Monday. These were Tropical Storm Hone, which brought heavy rain to Hawaii, Hurricane Gilma and Storm Hector.
In the Grand Canyon, a flash flood claimed the life of Arizona hiker Chenoa Nickerson, who was swept away into the Colorado River before her body was tragically discovered on Sunday.
The floods left several hikers trapped but more than 100 people were evacuated by UH-60 Blackhawk helicopters, after Arizona Governor Katie Hobbs activated the state’s National Guard.
