Knoxville residents are looking at a dynamic weather forecast as we close out 2025, with the National Weather Service (NWS) Knoxville anticipating some potentially hazardous conditions. According to a weather update, Sunday will see a mix of clouds and sun with temperatures peaking around 72°F, accompanied by light winds that will pick up with gusts as high as 25 mph. But as Sunday night rolls in, prepare for showers, mainly after 1 am, and a temperature drop to 37°F, with ongoing gusty conditions reaching up to 30 mph.
The NWS has also issued a Hazardous Weather Outlook that flags stronger southwesterly winds for Sunday afternoon through Monday, especially impacting the higher elevations with gusts potentially hitting 50 mph. Winds of 15 to 25 mph with gusts to 35 mph are expected for lower elevations starting Sunday afternoon, the NWS stated, providing a clear picture of the advisory to residents. The upcoming cold snap will bring temperatures down significantly, with wind chills nearing zero in elevated areas on Monday night and single digits to teens elsewhere.
Transitioning into Monday, the forecast predicts a 30 percent chance of lingering showers before 11 am, before the skies start to clear. The high should hover around 47°F, with a steady west wind that could usher in gusts around 25 mph again. The subsequent nights are expected to be cold with lows in the 20s, but skies should remain partly cloudy to clear.
Knoxville and the surrounding regions should keep their winter gear on hand, as Tuesday and Wednesday project sunny days but with notably chillier high temperatures, registering near 37°F and 44°F, respectively. The sun might offer some reprieve, but don't let it deceive, these days are forecast to end in the 20s as nighttime descends.
Moving forward through the week, the possibility of unsettled weather returns, culminating in a 30 to 40 percent chance of rain and snow on Friday night and Saturday. With the weather pendulum swinging from mild gusts and showers to frosty wind chills, Knoxville's communities are reminded to stay informed and prepare for these shifting conditions.
