Knoxville rolled out of bed Sunday, May 10, 2026, to patches of dense fog hugging the rivers and pooling in low-lying neighborhoods, trimming visibility in the usual trouble spots. Temperatures are sitting in the low 50s this morning, and forecasters expect the fog to thin between about 8 and 9 a.m. EDT, giving way to sunny skies and a high near 82°F this afternoon. If you are heading out for early Mother's Day plans, build in a little extra drive time, since visibility can still drop quickly in valley spots.
Afternoon Warmth, Small Overnight Rain Chance
Once the fog clears, expect a calm and mostly dry day, with highs near 82°F, west winds around 0 mph, and humidity easing through the afternoon. A weak cold front approaches late tonight, bringing a small chance of light showers overnight and a low near 57°F. Monday carries a higher chance of spotty rain with cooler highs. According to NWS Morristown, fog is the main hazard this morning, and you can see the setup in our basks then gets soaked outlook.
Commute Tips and Outdoor Plans
If you are driving early, leave extra time, use low-beam headlights, and keep a healthy distance from the car ahead, since high beams can make the fog glare worse. Most outdoor events should be in good shape by late morning as skies clear and winds stay light, so midday plans look solid. Airports and major road sensors are already reporting improving conditions, and travel should settle back to normal by mid-morning.
Looking Ahead
Forecasters expect a modest cool-down on Monday with more widespread rain chances later in the week and another front around Wednesday that could bring additional light showers. A noticeable warm-up is expected by next weekend, with highs back in the 80s across the valley. This briefing will be updated if any warnings or advisories change.
