Knoxville residents looking ahead to the Memorial Day weekend can expect a medley of showers and thunderstorms as reported by the National Weather Service in Knoxville. The detailed forecast released for the week paints a picture of increasing cloudiness today with a high near 73, calm winds, and no immediate precipitation, giving way to a slightly wetter outlook as the weekend progresses.

The chance of showers and thunderstorms tonight creeps up to 30%, with this trend intensifying into Sunday when the NWS anticipates a 70% probability of precipitation, the showers might be spliced by a thunderstorm especially during the afternoon hours, although calm winds are expected to persist, which in a way can be a silver lining for those wary of stormier conditions. Looking forward to Memorial Day itself, the chance of rain hovers around 60%, with showers likely after 2pm amidst temperatures peaking near 77 degrees, ensuring that backyard barbecues and outdoor festivities might require a backup plan.

As for the week that follows, a damp pattern settles in over Knoxville. Tuesday and Wednesday are slated for a 90% and 70% chance of showers and thunderstorms, respectively, the conditions remaining mostly cloudy with high temperatures approaching the 80-degree mark, a continuation of this wet spell set to last through to the end of the week, according to NWS, Knoxville.

For night owls and evening commuters, the outlook isn't much drier, with Monday and Tuesday nights anticipating heavy activity — a blend of showers and possible thunderstorms set to drench the region, and while the calm winds might not stir into gales, residents should still brace for bouts of nocturnal rainfall; the lows during these nights are projected to be around 63 and 65 degrees, respectively.
