Knoxville woke up under a gray blanket of clouds on Saturday, February 21, 2026, with temperatures already on the mild side and headed for an afternoon high near 60°F. A few light showers may brush the area early, but the real story is what comes next: a sharp turn to colder, windier weather by Sunday and a quick hit of snow in the mountains late tonight into Monday.
Today's Forecast and Morning Showers
Rain is a minor player to start the weekend, with just a slight chance of showers before 9 a.m. and totals generally under a tenth of an inch. From there, Knoxville is in for a mostly cloudy but comfortable Saturday, with highs near 60°F and a light north breeze of 0–5 mph, according to NWS Morristown.
Tonight Into Monday: Cool Down, Mountain Snow And Gusts
The quiet weather does not last long. Rain chances ramp back up late tonight, with a window of showers roughly between 8 p.m. and 4 a.m., as temperatures slip to around 34°F before edging into the upper 30s overnight. A passing cold front will tug colder air into East Tennessee and flip some of that moisture to a rain-and-snow mix over the higher terrain early Sunday.
Lower ridgelines below about 2,000 feet could see only a dusting to a few tenths of an inch. Elevations above 2,000 feet may pick up as much as 2 inches, and the very highest peaks could squeeze out locally higher amounts. At the same time, northwest winds will crank up Sunday into Monday, with valley gusts near 30 mph and mountain gusts pushing toward 40 mph. Those winds will drive wind chills into the single digits to below zero on the highest ridges, according to the National Weather Service Morristown.
What This Means For Travel
Between the colder air and the ramped-up winds, parts of the weekend and Monday will feel a lot harsher than the thermometer suggests. Secure trash cans, lawn furniture and anything else that might tumble down the street in a gust. Drivers in tall vehicles should be ready for some buffeting, especially on higher overpasses and more exposed stretches of roadway.
If you are headed into the Smokies Sunday night or Monday, treat the forecast seriously. Wet pavement can turn slick quickly when temperatures dip and snow starts mixing in at higher elevations. Check road conditions before you go, build in extra time and have winter gear handy. Around town, commuters should plan for gusty crosswinds and grab a warm extra layer for those early-morning errands.
Looking Ahead
After the cold shot, temperatures bounce back into the upper 50s by midweek. Rain is set to return Wednesday night into Thursday, bringing another round of showers and a warm high near 60°F on Thursday. Anyone banking on outdoor plans late in the week will want to keep an eye on updates, as the pattern looks ready to keep flipping between mild spells and brief brushes with wintry weather through early next week.
