Knoxville woke up to clouds and a cool breeze on Sunday, April 19, 2026, with temperatures near 48°F. The day will end on a much brighter note, with drier weather and sunshine breaking through for most neighborhoods by midafternoon and a high around 64°F.
Afternoon Clearing And Light North Winds
Low clouds and a few stray showers are sliding off to the east this morning, opening the door to mostly sunny skies and a north wind around 5 to 10 mph. Highs should top out near 64°F, with only a small chance that any lingering showers drop brief rain totals of just a few tenths of an inch, according to the National Weather Service in Morristown.
Cool Nights And Frost Risk In The Hills
Tonight will be mostly clear with lighter winds and lows around 43°F in the city. Higher-elevation spots north and east of Knoxville could slip into the 30s, which brings a small risk of patchy frost Monday night. Gardeners in outlying valleys might want to play it safe and cover up any tender plants.
Warming Trend And Weekend Storm Chance
Starting Tuesday, a warming trend takes over. Highs climb into the 70s on Tuesday, then reach near or above 80°F by Wednesday and Thursday. Southwest winds on Wednesday could gust up to about 20 mph. Rain chances make a comeback late Friday into Saturday, with a slight chance of evening storms Friday and showers and thunderstorms likely on Saturday, per the NWS forecast discussion. If you are planning outdoor events, earlier in the week looks like your best bet or at least have a fallback plan for the weekend.
What To Do Today
Think layers this morning, then shed a few by afternoon once the sun takes over. No watches or warnings are in effect for the area today, but it is worth checking back on the forecast as the warmer weather and late-week storm chances move in.
