In northwestern Montana, the season’s first snowflakes are anticipated due to “sharply colder air” brought on by a strong cold front moving through the region.
Conversely, the mid-Atlantic is bracing for “record heat,” with high temperatures predicted to linger for a couple more days in the Ohio and Tennessee Valleys.
The NWS remarks that a cold front has delivered relief from the heat in the northern Plains, while also igniting thunderstorms across the Midwest.
“As the front continues to progress eastward, record-breaking temperatures are predicted in the Mid-Atlantic, potentially hitting 100 degrees near Washington, D.C.,” they said.
On Tuesday, extreme heat warnings were issued across parts of the Midwest, with temperatures climbing into the 90s.
The last few days showcased diverse and extreme weather patterns across the U.S., swinging from heat waves to snowstorms and flash floods.
While many Midwestern areas struggled with sweltering heat, a cold front from the Gulf of Alaska brought early winter vibes to the West Coast.
Additionally, three tropical systems formed in the Pacific Ocean, including Tropical Storm Hone, which caused heavy rainfall in Hawaii, along with Hurricane Gilma and Storm Hector.
In a tragic incident, a flash flood in the Grand Canyon claimed Arizona hiker Chenoa Nickerson, who was swept into the Colorado River, with her body discovered on Sunday. Flooding left several hikers stranded, prompting rescue operations involving UH-60 Blackhawk helicopters after Arizona’s Governor activated the National Guard.
