Which radars cover Calvin?
The closest NEXRAD Doppler radar is KTLX (Oklahoma City, OK), about 63 miles west-northwest. 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 Calvin | View |
|---|---|---|---|
| KTLX Oklahoma City, OK | 63 mi west-northwest | 4,900 ft | Good — most storms and steady rain or snow show clearly |
| KINX Tulsa, OK | 92 mi north-northeast | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KSRX Fort Smith, AR | 109 mi east-northeast | 11,000 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.
