Which radars cover Four Square Mile?
The closest NEXRAD Doppler radar is KFTG (Denver/Boulder, CO), about 20 miles east-northeast. 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 Four Square Mile | View |
|---|---|---|---|
| KFTG Denver/Boulder, CO | 20 mi east-northeast | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KPUX Pueblo, CO | 92 mi south-southeast | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCYS Cheyenne, WY | 102 mi north | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
