Residents across parts of southwest North Carolina, east Tennessee, and southwest Virginia are bracing for a weekend of unsettled weather, complete with risks of strong thunderstorms and potential flooding, the National Weather Service in Morristown warned Friday. According to the latest forecast, today's overcast conditions in Knoxville could give way to patchy fog in the morning and a 30 percent chance of showers and thunderstorms in the afternoon, particularly after 5 pm.

The Knoxville temperature, a sticky 68 degrees with 100 percent humidity, sets the scene for potential thunderstorms later in the day, which can bring with them the threat of hail and damaging winds, according to the National Weather Service. Tonight, the chance of precipitation increases to 40 percent with the possibility of storms occurring mainly between 1 am and 5 am, with continued overcast skies and fog into the early morning.

Looking ahead to the weekend, starting Saturday, the forecast suggests partly sunny skies but with a 50 percent chance of showers and possible thunderstorms in the afternoon. This pattern of showers and storms is expected to continue into Sunday, with a 40 percent chance of precipitation during the day, increasing to an 80 percent chance overnight, possibly heralding a thunderstorm after 2 am.

Memorial Day celebrations may need an umbrella, with showers and thunderstorms highly likely, mainly before 2 pm under a high near 84. The special weather statement cited a "period with a low tornado threat" in the Sunday-Monday timeframe, and residents are advised to stay vigilant. Heavy rainfall over the weekend also raises concerns about localized flooding.

For those hitting the roads early, the special weather statement also highlighted patchy dense fog affecting some areas this morning, recommending travelers "plan extra time and use low beam headlights." The fog and a mix of serene sunny spells and bouts of heavy downpours is a stark reminder of the rapidly changing spring weather that can impact outings and outdoor plans.
