According to recent forecasts, Tennessee is preparing for a weekend of rain and thunderstorms. The National Weather Service has issued warnings that a cold front will move across the state, bringing with it increased moisture and atmospheric instability, which will cause thunderstorms to develop. The storms could bring heavy rain, potentially causing localized flooding in low-lying areas and places with inadequate drainage. Strong, gusty winds are also expected, which could knock down trees and power lines, resulting in power outages.
