We begin this Tuesday with a gorgeous view from Clingmans Dome. Current temperatures in the valley lie in the mid to upper 30's with a few high clouds overhead. Anticipate increased cloud cover towards the overnight hours tonight as a system will work in for your Wednesday. High's today in the upper 50's.
Looking ahead, there is the system I am referring to. Bringing all weather phenomena from snow, ice, and rain, it will move east through the day today arriving to East Tennessee by the second half of the day tomorrow. Though we won't see snow for some time, prepare for some rainfall in the evening to overnight hours tomorrow. The SPC (Storm Prediction Center) has issued a Marginal risk of severe storms from Middle Tennessee and west. This will be the best area to watch for gusty winds, heavy downpours, and lightning. Given the current timing, showers & any storms will weaken as they work east (good news here at home).
Taking a look at model guidance, things stay dry overnight tonight and early Wednesday. By the late-morning to early afternoon, a few could see an isolated shower, otherwise things stay cloudy. For the evening though, showers begin working in from the west. As you can tell, this line of showers/ isolated storms begins breaking down once it moves through Middle Tennessee. Rainfall will be similar to our last system with upwards of a quarter of an inch possible (locally higher amounts possible).
The all important Thanksgiving forecast looks beautiful with improving skies through the day and high's very mild in the mid to upper 60's. Thanksgiving will likely be our best day Wednesday through the weekend, so enjoy the holiday!
