Which radars cover St. Xavier?
The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 51 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 St. Xavier | View |
|---|---|---|---|
| KBLX Billings, MT | 51 mi west-northwest | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KRIW Riverton, WY | 169 mi south-southwest | 22,100 ft | Limited — the beam overshoots the lowest part of storms |
| KGGW Glasgow, MT | 197 mi north-northeast | 28,500 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.
