Which radars cover Boulder?
The closest NEXRAD Doppler radar is KICX (Cedar City, UT), about 81 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 Boulder | View |
|---|---|---|---|
| KICX Cedar City, UT | 81 mi west-southwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGJX Grand Junction, CO | 191 mi east-northeast | 27,000 ft | Limited — the beam overshoots the lowest part of storms |
| KFSX Flagstaff, AZ | 232 mi south | 37,500 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.
