Todays weather in Knoxville TN - Saturday - 30 May 2026

Two flood alerts are active in Knoxville right now, and this morning's briefing puts the most important information first. A Flood Watch runs until 2:00 PM, and a Flood Advisory was in place through mid-morning — both tied to heavy rainfall, warm temperatures, and serious runoff potential across East Tennessee.Current conditions: 81 degrees with showers and thunderstorms already rolling through. The rain chance sits at 82 percent — not a maybe. Winds are light out of the east at zero to five miles per hour, so this is purely a rain event. If you're near low-lying areas or small streams, take the flood alerts seriously.For your commute, expect standing water on roads, reduced visibility, and slow going until the heavier activity eases after 2:00 PM. Bring an umbrella, know your route, avoid pooling underpasses, and consider leaving early or waiting it out. Low-clearance vehicle drivers should plan carefully.Tonight calms down considerably — storms taper off by 8:00 PM, skies go partly cloudy, and the low drops to a comfortable 61 degrees.Looking ahead, Sunday offers a pleasant window with mostly sunny skies and a high near 82, before storms return Sunday night. Monday carries a 73 percent storm chance, so this pattern has more to give. Relief arrives Tuesday, and Wednesday through Friday looks genuinely sunny and pleasant with highs near 79.For now: watch the flood alerts, give yourself extra time, and stay aware on the roads. Storms now, clearing later — Knoxville, you've got this.This episode includes AI-generated content.
