Friday, February 13, starts sunny and calm across Knoxville, with morning temperatures in the mid-40s. Skies stay clear, and the afternoon warms to a high near 55, with light northeast winds.
Weekend Rain Risk
The quiet stretch does not last long. Rain is likely Saturday night (Feb. 14), with the main, widespread rainfall moving in on Sunday (Feb. 15). The National Weather Service in Morristown notes a 40–50% chance that some spots could see an inch of rain or more, which would mark the heaviest rainfall of the week for the area, according to NWS Morristown.
Timing And Travel
Showers are expected to arrive late Saturday evening and ramp up overnight, with steadier, heavier rain through Sunday. The wettest window currently looks to be Sunday morning into the afternoon. Winds in the valleys should stay light, around 0–5 mph, while the Cumberland Plateau could turn breezy from Saturday night into Sunday morning. Anyone commuting or planning outdoor activities on Sunday should prepare for slower travel and soggy conditions.
Why This Matters
This round of rain follows an extended dry spell across parts of Tennessee, so meaningful accumulation will help replenish soil moisture and local streams. The U.S. Drought Monitor still shows areas of moderate to severe drought across central and eastern Tennessee, which makes Sunday’s rainfall totals particularly important, according to the U.S. Drought Monitor.
Fast Tips
Plan by packing rain gear and giving yourself extra time for Sunday travel, and avoid driving through any standing water. Check the latest forecast updates and road conditions before heading out.
