Knoxville's Thursday starts cool and calm, with temperatures around 45 degrees and patchy fog possible early. Sunshine should take over, sending the afternoon to near 73 degrees with no rain in sight. It is the kind of October setup that asks for a jacket at breakfast and makes you question it by lunch.

Patchy fog is possible near rivers and lakes Thursday morning. After that, both days should turn sunny, with highs near 73 Thursday and 72 Friday, plus light winds, according to the National Weather Service in Morristown.

Weekend Plans Get A Dry Forecast

Saturday and Sunday stay sunny and mild, with highs around 72 and 70 degrees and overnight lows in the low-to-mid 40s. Monday remains mostly sunny near 73, while Tuesday stays mostly sunny near 74 and Wednesday remains mostly sunny to partly sunny near 73. The forecast stays dry through Wednesday.

The updated outlook extends Knoxville's dry streak into Wednesday, adding to the sunny 70s pattern covered in Hoodline's earlier forecast. No watches, warnings or advisories are listed for the area, while the weather service says afternoon humidity will run low, making cool mornings and dry air the recurring theme.
