Which radars cover Hartman?
The closest NEXRAD Doppler radar is KSRX (Fort Smith, AR), about 43 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 Hartman | View |
|---|---|---|---|
| KSRX Fort Smith, AR | 43 mi west-southwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KLZK Little Rock, AR | 88 mi east-southeast | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KINX Tulsa, OK | 120 mi west-northwest | 12,700 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.
