Which radars cover Nashua?
The closest NEXRAD Doppler radar is KGGW (Glasgow, MT), about 13 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 Nashua | View |
|---|---|---|---|
| KGGW Glasgow, MT | 13 mi west-northwest | 700 ft | Excellent — the lowest scan sees close to the ground |
| KBLX Billings, MT | 190 mi southwest | 26,800 ft | Limited — the beam overshoots the lowest part of storms |
