KOHX radar — Nashville, TN
KOHX is the National Weather Service's WSR-88D Doppler radar for the Nashville area, operated with the NWS office OHX. View it live in TALON — the loop, super-res reflectivity, storm-relative velocity, rotation and correlation coefficient.
| Station | KOHX (Nashville, Tennessee) |
|---|---|
| Location | 36.2470°, -86.5630° · Wilson County |
| Elevation | 676 ft above sea level |

| Products in TALON | Super-res reflectivity (0.25 km), velocity, storm-relative velocity, rotation (azimuthal shear), correlation coefficient PRO |
How high can KOHX see?
A radar beam travels in a nearly straight line while the Earth curves away underneath it, so the farther a storm is from KOHX, the higher above the ground the radar is looking. Tornadoes start in the lowest few thousand feet, so storms close to the radar show low-level rotation much better.
| Distance from KOHX | Lowest scan (0.5°) | Next scan (1.5°) |
|---|---|---|
| 10 mi | 500 ft | 1,400 ft |
| 25 mi | 1,500 ft | 3,800 ft |
| 50 mi | 3,600 ft | 8,200 ft |
| 75 mi | 6,300 ft | 13,200 ft |
| 100 mi | 9,600 ft | 18,800 ft |
| 150 mi | 18,200 ft | 32,000 ft |
Height of the beam's center above the radar, using standard refraction. Terrain can raise or block the beam.
Severe weather inside KOHX's range
Since 1950, NOAA has recorded 548 tornadoes within 60 miles of the KOHX radar, 136 of them rated EF2/F2 or stronger. They have been most common in May and April. The strongest was an F5 on April 16, 1998, which passed about 52 miles south-southwest of the radar and caused 3 deaths. The most recent was an EF1 on November 22, 2025, which touched down about 44 miles northwest of the radar.
Hail: 1,368 reports of hail 1 inch or larger within 60 miles of the KOHX radar since 1955, 118 of them 2 inches or larger. The largest was 4.50-inch hail (grapefruit size) on June 4, 1985.

KOHX radar FAQ
How often does KOHX update?
Every NEXRAD radar completes a full scan about every 4–6 minutes in storm mode, and repeats the lowest tilt more often (SAILS) during severe weather. TALON loads each new scan as it arrives.
What is the range of KOHX?
Reflectivity reaches about 290 miles and velocity about 185 miles, but useful low-level detail is within roughly 100 miles — see the table above.
Is KOHX down?
Radars occasionally go offline for maintenance. When one does, TALON's US radar map fills the gap from neighboring radars (KHPX, KHTX, KLVX).
