The Knoxville area is currently under a Dense Fog Advisory, with visibility dropping to less than one mile in certain locations, according to the National Weather Service in Morristown, TN. The advisory, which extends until 9:00 a.m. EDT this morning, affects Anderson, Blount, Smoky Mountains, Knox, Loudon, North Sevier, Northwest Blount, Roane, and Sevier Smoky Mountains Counties. The reduced visibility has the potential to make driving conditions dangerous for commuters and residents alike.

In addition to the fog, the forecast suggests a 70% chance of showers and thunderstorms today, mainly before 2:00 p.m. and then possibly again after 4:00 p.m. According to NWS Knoxville, expected rainfall amounts may vary between a quarter and half an inch. As the humid air holds its breath, the possibility of local flooding and strong to severe storms later this afternoon and evening remains a concern for the area. The threat of hazardous weather appears low for the rest of the week, though scattered showers and thunderstorms continue to dance in the forecast.

Tonight, the weather service anticipates an 80% chance of showers and possibly a thunderstorm before 11:00 p.m., with additional patchy fog rolling in after 11:00 p.m. Residents planning nighttime activities should stay vigilant and prepare for potential disruptions caused by the weather conditions. The low is expected to hover around 61 degrees, with a southwest wind around 5 mph.

Looking ahead to the weekend, the forecast sees a 60% chance of showers and thunderstorms on Saturday, especially before 11:00 a.m., and then again between 11:00 a.m. and 2:00 p.m. The skies are predicted to partially clear by Saturday night, with a low around 52 degrees, and a north wind around 5 mph providing a gentle reprieve. 

Residents can look forward to more agreeable conditions by Sunday, with mostly sunny skies and a high near 72 degrees.
