Which radars cover Blaine?
The closest NEXRAD Doppler radar is KMRX (Knoxville, TN), about 16 miles east. 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 Blaine | View |
|---|---|---|---|
| KMRX Knoxville, TN | 16 mi east | 900 ft | Excellent — the lowest scan sees close to the ground |
| KJKL Jackson, KY | 102 mi north-northeast | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGSP Greer, SC | 120 mi southeast | 12,800 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.
