Which radars cover St. Ann Highlands?
The closest NEXRAD Doppler radar is KFTG (Denver/Boulder, CO), about 50 miles east-southeast. 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 St. Ann Highlands | View |
|---|---|---|---|
| KFTG Denver/Boulder, CO | 50 mi east-southeast | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KCYS Cheyenne, WY | 87 mi north-northeast | 7,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPUX Pueblo, CO | 126 mi south-southeast | 13,700 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.
