Which radars cover Marmarth?
The closest NEXRAD Doppler radar is KBIS (Bismarck, ND), about 154 miles east-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 Marmarth | View |
|---|---|---|---|
| KBIS Bismarck, ND | 154 mi east-northeast | 19,000 ft | Limited — the beam overshoots the lowest part of storms |

| KGGW Glasgow, MT | 182 mi northwest | 25,000 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.
