Which radars cover Tennessee?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 81 miles east-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Tennessee | View |
|---|---|---|---|
| KILX Lincoln, IL | 81 mi east-southeast | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 84 mi north | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 119 mi south | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.

Tennessee radar FAQ
Where is the nearest weather radar to Tennessee, IL?
KILX (Lincoln, IL), about 81 miles east-southeast. KDVN (Quad Cities, IA) is 84 miles away and also covers the area.
Does radar show snow in Tennessee?
Yes. TALON colors snow blue, a rain–snow mix pink and freezing rain purple using NOAA's precipitation-type analysis. Over Tennessee the lowest scan from KILX is about 7,000 ft up, so light snow from shallow clouds can be under-shown — check NWS winter alerts too.
Is TALON's radar for Tennessee free?
Yes — the US radar loop, rain/snow/ice colors, flash-flood risk, storm tracks and NWS warnings are free in any browser. Close-up radar, rotation detection and longer forecasts are part of TALON Pro.
Should I rely on radar for my safety?
