A mild and dry weather pattern will continue through Wednesday, with highs in the mid 60s-lower 70s and lows in the 40s. However, a strong cold front will sweep across the region Wednesday night, bringing a fast-moving band of showers (and a few thunderstorms) during the evening hours. Strong north winds will send a much colder airmass into the TN Valley in the wake of the front, with skies remaining mostly cloudy through Friday.
