Cooler Weather Spreads Across Midwest, Northeast With Scattered Showers

A widespread pattern of cooler, less humid weather is moving across several U.S. regions following recent heat and storms. Areas including New Hampshire, West Virginia, South Dakota, and Kansas are experiencing temperatures mostly in the 70s and 80s with morning lows in the 50s and 60s, along with reduced humidity and increased sunshine expected through the weekend. Rain showers and thunderstorms are tapering off in many places, though isolated storms and some rain chances persist into Friday or Saturday, particularly in southern and central zones. Canadian high pressure systems are bringing cooler air and clearer skies to much of the country, providing a break from muggy conditions and heat. However, smoke from Canadian wildfires is affecting parts of South Dakota, causing hazy skies despite minimal surface impact. Overall, a pleasant and cooler weekend with low humidity and sunshine is forecast, with temperatures warming slightly early next week and a potential return of scattered afternoon storms.
