Which radars cover Williams?
The closest NEXRAD Doppler radar is KFSX (Flagstaff, AZ), about 73 miles 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 Williams | View |
|---|---|---|---|
| KFSX Flagstaff, AZ | 73 mi southeast | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWA Phoenix, AZ | 138 mi south-southeast | 16,000 ft | Limited — the beam overshoots the lowest part of storms |
| KESX Las Vegas, NV | 156 mi west-northwest | 19,300 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.
