Forecast

Lenoir City's weather is humid subtropical, which means it's usually warm and humid in summer, and cool in winter. The Appalachian Mountains surrounding Lenoir City affect air pressure, making it change frequently. Valley locations like Lenoir City tend to have lower air pressure due to the surrounding mountains. When air rises over mountains, it cools, and pressure drops.

In summer, high pressure brings warm air from the Gulf of Mexico, making it hotter and more humid. Low pressure from the Atlantic Ocean brings cooler air, making it milder. Winter brings cold air from Canada, causing low pressure, which brings cold fronts and snow. Spring and autumn have mild temperatures with moderate air pressure.

During spring, warm air from the Gulf clashes with cold air from Canada, causing unstable air pressure, leading to thunderstorms. In autumn, cooler air from Canada dominates, bringing stable air pressure and clear skies. Lenoir City's geography, with surrounding mountains and nearby lakes, influences air pressure patterns, making weather forecasts unpredictable.
