A strong cold front is on its way today with heavy showers and a few storms possible this evening & overnight. A secondary front will arrive late work week providing another cool down Friday and the weekend. High's will be nearly 20 degrees cooler tomorrow when compared to today's expected high's.
The SPC has placed a majority of east Tennessee under a Marginal risk for severe weather. The brunt of heavy showers and storms will stay contained to the Plateau, but some could roll through the valley this evening & early overnight. In addition to the Marginal severe risk, a Marginal risk for flash flooding (5-10%) is also in place (more details in the forecast video below). The main threat will be localized heavy winds and downpours. We will see gusty winds throughout the day (up to 20 mph) as southern flow dominates ahead of the front.
Most rainfall will take place between 8 pm and midnight with a few lingering showers into Tuesday morning. By Tuesday afternoon, dry air from the north and west will funnel in providing overnight low's into the 40's. Temperatures will begin increasing back mid-week to the lower 70's before another cold air mass knocks temps back down to the lower 60's for Friday.
With an active start to the work week, tune in for updates. Localized heavy showers and storms will be followed by cool temperatures into Tuesday. Be sure to break out those jackets if you haven't already because temperatures will be trending below average all week long.
