Knoxville weather forecast is looking grey and stormy, according to the National Weather Service. Monday might still see some sun peeking through, but don't get too cozy in your spring attire; by the afternoon, there's a 20 percent chance of showers with the day's high barely scraping 75 degrees. NWS predicts a restless night with showers and thunderstorms playing a game of tag - chances of rain are fifty-fifty before 11 p.m., then holding steady for showers till dawn breaks over a potentially stormy Tuesday morning.
Come Tuesday, don't bother trying to stay dry. NWS warns showers and thunderstorms are near-guaranteed, so better to fully embrace the 90 percent chance of precipitation. The skies are set to open with new rainfall amounts ranging from a modest tenth to a more noticeable quarter of an inch, though thunderstorms could easily ramp those numbers up. With an east wind that's due to shift southwest by morning, at 5 to 10 mph, the high for the day will hover close to 76 degrees.
Wednesday isn't looking any better with NWS doubling down on their storm forecasts. Showers, thunderstorms, and a high of 72 degrees – it's a trifecta that'll keep umbrellas up and spirits probably damp. The wind, now from the west, could show its strength with gusts potentially reaching 20 mph. The chance of precipitation persists at a stubborn 90 percent, making midweek plans questionable at best.
Thursday may offer a brief respite from the rains, just in time for the clear skies to coax temperatures up to a more spring-like 80 degrees. The reprieve will be short-lived though, with NWS flagging a 20 percent chance of showers in the wee hours post-2 a.m. Then, as the week draws to a close, Friday threatens to wash out any hopes of a dry end with a 60 percent chance of more showers and thunderstorms well into the evening.
Even the weekend isn't safe from nature's watery wrath. On Saturday, there's a fair 40 percent chance you'll be dodging raindrops under mostly sunny skies, with high temperatures reaching a hopeful 80 degrees. As night falls, the NWS suggests that the likelihood of showers and thunderstorms will decrease to 20 percent. But hold onto those umbrellas; Sunday sings the same soggy tune with a 40 percent chance for more showers and thunderstorms, despite a forecast promising mostly sunny skies and highs aiming for 81 degrees.
For detailed updates and to plan accordingly, keep an eye on the NWS Knoxville page. Whether it's the slight drizzle or the full might of a spring thunderstorm, Knoxville residents will need to stay weather-aware this week.
