Knoxville residents will want to keep their umbrellas handy and prepare for potential weather disruptions as the National Weather Service in Morristown has issued a forecast packed with showers and thunderstorms. Today's climate sets the stage with "showers and thunderstorms, mainly before noon" transitioning into a likelihood of storms continuing "after 5pm," with rainfall up to half an inch possible, as noted in their latest update.

Adding to the soggy outlook, the Weather Service cautions that tonight could witness "showers and thunderstorms likely, mainly before 1 am." Residents should be wary as calm conditions bring a low hovering at around 64 degrees with south winds turning calm, culminating in a 60 percent rain chance, the NWS predicts.

Looking ahead, the weather isn't bound to improve significantly for weekend plans. Friday forecasts promise a "slight chance of showers and thunderstorms before 8am." Even as the Day progresses, showers and thunderstorms remain likely post 2 pm, with the National Weather Service warning of new rainfall amounts of less than a tenth of an inch, except higher amounts possible in thunderstorms.

The weekend spells trouble for outdoor events as "showers and thunderstorms likely, mainly before 8pm." Saturday doesn't grant a reprieve either, with somewhat sunny skies giving way to continued 60 percent chance of showers and thunderstorms. Reinforcing the unsettled pattern, the NWS anticipates a similarly punchy chance for Sunday and into Memorial Day, setting the holiday's high near 82 amidst showers and possible thunderstorms.

For those in East Tennessee and the surroundings, the message is clear: be prepared for a turbulent and wet end to May. Spotters are on alert too, as the NWS highlighted the possibility of conditions that could call for their reports during this weather spell, especially between today and Monday.
