Which radars cover Roy?
The closest NEXRAD Doppler radar is KBLX (Billings, MT), about 104 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 Roy | View |
|---|---|---|---|
| KBLX Billings, MT | 104 mi south | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
