Which radars cover Oak Grove?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 57 miles west-southwest. 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 Oak Grove | View |
|---|---|---|---|
| KMRX Knoxville, TN | 57 mi west-southwest | 4,200 ft | Good — most storms and steady rain or snow show clearly |
| KJKL Jackson, KY | 94 mi north-northwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGSP Greer, SC | 107 mi south | 10,700 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.
