The latest weather update from the National Weather Service in Knoxville presents a concise forecast for the days ahead—offering a glimpse of sunny skies and potential showers as the week progresses. According to the NWS Knoxville, today's early cloudy skies are set to clear gradually with a calmer wind turning west in the afternoon and a high reaching a modest 36 degrees.

Tonight's forecast shows mostly clear conditions with temperatures dipping to around 24 degrees; however, gusts could reach as high as 20 mph, changing the perceived chill for anyone caught outside. The wind is anticipated to come in from the southwest, pushing through at 5 to 10 mph. Looking forward to Martin Luther King Day, the NWS predicts sunny weather with the high nearing 38 degrees—a mild respite—and winds from the west around 10 mph but with possible gusts up to 20 mph, as reported earlier today.

The coming week appears to continue with the theme of sunny or mostly sunny days, offering fair weather particularly on Tuesday and Wednesday. With highs forecasted at 35 and 47 degrees respectively, light winds are to replace the previous calmness, possibly bringing some gusts into play. However, by Wednesday night, there’s a 20 percent chance of rain showers, potentially mixing with snow after 5am, this slight variability marks a subtle shift in an otherwise stable weather pattern.

As Thursday arrives, the likelihood of snow showers lingers at 10 percent before 7 am according to NWS Knoxville, but the day is primarily set to be mostly sunny with a high around 45 degrees; by Thursday night the skies are again mostly clear, with a low around 24 degrees. Transitioning into the weekend, Knoxville residents can anticipate warmer weather, with highs reaching the 50s, although showers become more probable with a 30 percent chance on Friday night and increasing to a 40 percent chance by Saturday.
