Which radars cover Jefferson City?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 6 miles northeast. 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 Jefferson City | View |
|---|---|---|---|
| KMRX Knoxville, TN | 6 mi northeast | 300 ft | Excellent — the lowest scan sees close to the ground |
| KJKL Jackson, KY | 102 mi north | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGSP Greer, SC | 111 mi southeast | 11,300 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.
