Knoxville woke up to clear skies and about 57°F at McGhee Tyson this morning, the kind of calm, pleasant start that screams spring. It will stay warm and mostly friendly through much of the day, but a late‑day system is set to shake things up tonight. Outdoor plans look fine for most of the afternoon, although it will turn breezy and feel pretty blustery at times.
Afternoon Gusts And Spotty Showers
Afternoon highs should top out near 83°F with southwest winds around 0 to 15 mph and gusts that could reach 25 mph. Mostly sunny skies will gradually give way to a slight chance of showers around midday and a better shot at rain between roughly 2 and 5 p.m., with overall rain chances near 40%.
The main event arrives Saturday night into early Sunday, when a more widespread line of showers and thunderstorms is expected to move through. Rain is a near‑lock, with new rainfall totals around three‑quarters of an inch to one inch possible. Behind the front, forecasters are looking for a noticeable cool‑down that may allow frost to develop in the colder spots Monday through Wednesday mornings, according to the National Weather Service Morristown.
Sunday And The Week Ahead
Rain should wind down Sunday morning, with lingering showers still possible into the early afternoon. The high will only make it to about 66°F, a clear drop from today’s warmth.
Cooler air settles in for early next week, with daytime highs holding in the 60s and chilly overnight lows dipping into the 30s to low 40s across inland spots and higher terrain. The silver lining for anyone tired of dodging raindrops is that dry weather looks likely through the workweek, with a gradual warm‑up by midweek.
How To Prepare
If your plans involve being outside tonight, consider shifting them earlier or having a solid backup plan. Gusty winds can knock over unsecured items, and standing water could slow you down on the roads.
For Sunday morning drivers, plan on giving yourself extra time. Heavy downpours could reduce visibility and make travel slick, so keep an eye on updated forecasts before heading out and be ready for changing conditions.
