Which radars cover Grass Range?
The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 82 miles south. 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 Grass Range | View |
|---|---|---|---|
| KBLX Billings, MT | 82 mi south | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KTFX Great Falls, MT | 125 mi west-northwest | 13,500 ft | Limited — the beam overshoots the lowest part of storms |
| KGGW Glasgow, MT | 130 mi northeast | 14,500 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.
