The Knoxville area is expected to see warm and dry conditions for the rest of the workweek, with a slight chance of late-day/evening showers on Thursday, mainly north of I-40. Temperatures will reach the mid-80s on Thursday, just shy of the record high of 87°F set in 1896. Friday is forecast to be breezy and warm, with a near-record high, while Saturday could see temperatures approach the 90°F record.

Why it matters

The warm and dry conditions in Knoxville this week increase the risk of wildfires, as winds remain elevated and humidity levels are low. The potential for scattered showers on Thursday evening could provide some relief, but overall the region is experiencing an extended period of above-average temperatures.

The details

Thursday's forecast calls for continued warm temperatures, with highs reaching the mid-80s. However, the area will see an increase in cloud cover, which may prevent temperatures from reaching the record high of 87°F set in 1896. There is a 20% chance of late-day/evening showers and thunderstorms, mainly north of I-40 and closer to the Tennessee/Kentucky border. Friday is expected to be breezy and warm, with a near-record high temperature. Saturday could see temperatures approach the 90°F record, with increasing cloud cover and a chance of scattered showers and thunderstorms in the evening.

  • Tonight: Increasing clouds, mild and dry. Winds are light. Low: 60°.
  • Tomorrow: Continued warm, but with a few more clouds, along with a slight chance (20%) of a late-day/evening storm near the Plateau/S.E. Kentucky areas. High: 85° (Record: 87°/1896).
  • Thursday night: Spotty showers/rumbles during the evening, mainly north of I-40. Staying mild. Low: 61°.
  • Friday: Breezy and warm with a near-record high and dry. High: 86°. (Record: 90°/1896).
  • Saturday: Increasing cloud cover, with a chance of scattered showers and thunderstorms in the evening. Highs in the upper 80s, approaching the record of 90°F set in 1896.

The weather pattern is expected to remain tranquil as the region moves into a new work week, with slightly below-average temperatures and sunshine on Monday. Temperatures will then start to warm up again on Tuesday and Wednesday, with highs in the 70s and lows in the 40s.

The takeaway

The extended warm and dry conditions in Knoxville this week highlight the ongoing risk of wildfires in the region, as winds remain elevated and humidity levels are low.
