The National Weather Service in Knoxville is forecasting a tumultuous mix of weather patterns over the coming days. According to their latest update on NWS website, residents can expect showers and thunderstorms, particularly before 2 pm today, with the skies clearing later in the evening. Despite the overcast start at 64°F this morning, Knoxville should see a partly sunny day with a high near 80°F. A calm wind is expected to gain strength, turning southwest at around 5 mph in the afternoon.

Likely providing a brief respite, the weather tonight will shift to mostly clear skies with a low hovering around 62°F.

The sun will mostly manage to shine through, pushing temperatures to a high near 83°F, while gusts could reach up to 20 mph. New rainfall could amount to up to a quarter of an inch, but thunderstorms might bring higher totals.

Continuing the mixed bag of weather, Friday's forecast is promising, featuring sunny skies and a high near 89°F, with a light wind turning southwest. However, the night will bring with it a slight chance of showers and thunderstorms, possibly starting after 2 am, while the low settles around 66°F.
