Jonesborough sits in the Appalachian foothills of northeastern Tennessee, where nearby ridges and valleys shape local weather. Rain falls in every season, and passing fronts can shift conditions quickly. Low pressure often brings clouds and rain; rising pressure behind a front usually brings clearer skies.
Nearby Appalachian ridges can lift moist air, so higher slopes may get more rain than sheltered areas. Valleys can hold colder air on calm winter nights, making frost or fog more likely there. Higher elevations also tend to stay cooler than lower spots.
Summers are warm and humid, with frequent afternoon showers and thunderstorms. Spring brings changeable temperatures and strong fronts. Autumn is often milder and drier, though rain still occurs. Winters are cool, with occasional snow, freezing rain, or icy roads; amounts vary from year to year.
