Another bout of moderate rain is in the forecast late tonight and through much of Wednesday. Typically this wouldn't be too much of a concern but with the heavy rainfall we received over the weekend, a marginal risk for flash flooding is in place. Isolated flash flooding will be possible, specifically for those in low-lying and flood prone areas.
Analyzing model guidance, scattered showers arrive late tonight and become widespread throughout Wednesday. By Wednesday night, clearing will persist allowing for overnight lows around freezing. Some locations will even see mid to upper 20's overnight. The Smokies will have an opportunity for a light snowfall Wednesday night, as model guidance is hinting at upwards of an inch for the highest peaks. Into Thursday, high's for most will stay in the 40's and overnight lows will be in the teens and 20's.
Looking at the progression of the cold front tomorrow, it is clear to see the temperatures gradient between Middle and Eastern Tennessee. A 20 degree swing can be seen across the state as a powerful late-winter like system works through. Fortunately, dry conditions will prevail Thursday onward with warming temperatures as well.
Look for showers to lead to isolated flash flooding through tomorrow. Following, a cold air mass will take hold for Wednesday night through Friday before a gorgeous Easter weekend finds us.
