Knoxville woke to clear skies and a chilly 45 degrees Friday morning, but patchy fog remains possible before 9 a.m. Sunshine should take over quickly, sending temperatures to 72 degrees by afternoon with no rain in sight.

Foggy Starts, Sunny Afternoons

The National Weather Service in Morristown expects variable or light northwesterly winds as the fog lifts. Friday night will stay mostly clear, with temperatures falling to around 41 degrees before patchy fog returns after 5 a.m. Saturday.

Saturday brings another sunny afternoon near 72 degrees, followed by a mostly clear night and a low around 44. Sunday stays bright and mild, with a high near 70 and another crisp overnight low around 42.

Dry Stretch Runs Through Thursday

Monday should reach 73 degrees under sunny skies, while Tuesday warms to about 74 with mostly sunny conditions. Wednesday and Thursday remain mostly sunny, with highs near 73 and 75 degrees, respectively.

The latest update extends Knoxville's dry spell through Thursday, building on Hoodline's previous forecast. Afternoon humidity will run low, but light winds should keep fire-weather concerns limited, and no watches, warnings or advisories are listed for the area.
