Finally the end of the work week has arrived but with some changes in the weather forecast. We are starting the morning with patchy fog and partly cloudy skies and will transition to partly cloudy skies this afternoon. High's remain warm in the upper 70's with clouds increasing throughout the later half of the day. A look at the SPC shows a Marginal Risk for severe storms just to the west. A line of showers & storms ahead of a cold front will work through late tonight and into Saturday morning. The good news is these will weaken as they move east, but some thunder/lightning and some gusty winds aren't out of the question.
Looking at model guidance, we see light scattered showers across East Tennessee initially tonight. Working further into the overnight hours and into Saturday morning, the line associated with a cold front will work through. As mentioned, the heavier showers/storms will stay to the west but a few strokes of lightning and gusty winds in heavier pockets are possible as we get into Saturday. By Saturday afternoon, things will calm back down with cloudy skies overhead. Sunday and early next week will all be similar with partly to broken skies and a few afternoon isolated showers possible.
Rainfall totals through Saturday afternoon will be in the half an inch to inch mark. Totals will vary given heavier pockets of showers/thunderstorms will provide more rainfall, but overall upwards of half an inch will likely be the average. With severe potential very low, this will be a good opportunity to receive a fresh bed of rainfall and keep any potential drought at bay.
That will wrap it up today, but we will be providing updates on social media as this line of showers works closer. If you don't follow us on Twitter or Facebook, you can follow along by viewing our tweets along the right side of this page. Have a great weekend and anticipate a big swing in temperatures in the next 7-10 days (more details to come Monday).
