Which radars cover Rocky Boy's Agency?
The closest NEXRAD Doppler radar is KTFX (Great Falls, MT), about 93 miles 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 Rocky Boy's Agency | View |
|---|---|---|---|
| KTFX Great Falls, MT | 93 mi southwest | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGGW Glasgow, MT | 145 mi east | 17,200 ft | Limited — the beam overshoots the lowest part of storms |
| KBLX Billings, MT | 175 mi south-southeast | 23,400 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.
