Which radars cover Grenora?
The closest NEXRAD Doppler radar is KGGW (Glasgow, MT), about 127 miles west-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 Grenora | View |
|---|---|---|---|
| KGGW Glasgow, MT | 127 mi west-southwest | 13,800 ft | Limited — the beam overshoots the lowest part of storms |
