Which radars cover Grover?
The closest NEXRAD Doppler radar is KCYS (Cheyenne, WY), about 36 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 Grover | View |
|---|---|---|---|
| KCYS Cheyenne, WY | 36 mi west-northwest | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KFTG Denver/Boulder, CO | 77 mi south-southwest | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPUX Pueblo, CO | 167 mi south | 21,500 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.
