Knoxville is waking Sunday, October 25, to clear skies and a cool 45-degree start, but the afternoon has a much softer plan: sunshine and a high near 72. Rain is not expected, and light northeast winds should stay between 0 and 5 mph as the city warms up.

According to the National Weather Service in Morristown, tonight will stay mostly clear with temperatures dropping to around 45 degrees. Monday brings another sunny afternoon near 73, with calm conditions and no rain in sight.

Sunny Afternoons, Jacket-Worthy Nights

The warm-up continues Tuesday, when mostly sunny skies push the high to about 76 degrees. Tuesday night will turn mostly cloudy with a low near 49, followed by a mostly cloudy Wednesday afternoon near 74 degrees.

Thursday’s high is expected to be near 72 to 73 degrees, while Friday reaches about 78 under mostly sunny skies. Some overnight lows will be in the low-to-mid-40s.

Halloween Looks Mild And Mostly Dry

Saturday, Halloween, is shaping up to be partly sunny and unusually mild for late October, with a high near 79 degrees. Clouds increase Saturday night.

The extended outlook adds several warmer days to the dry pattern described in Hoodline's earlier Knoxville forecast. No watches, warnings or advisories are listed for the area, making the next several days favorable for outdoor plans.

Light Winds But Very Dry Air

Winds should stay light or calm through much of the week, but afternoon humidity is expected to fall into the 30s and even the upper 20s on some days. That combination should keep fire-weather concerns limited, though anyone using outdoor flames should still be careful with dry leaves and vegetation.
