Which radars cover Williams?
The closest NEXRAD Doppler radar is KBBX (Beale AFB, CA), about 36 miles 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 Williams | View |
|---|---|---|---|
| KBBX Beale AFB, CA | 36 mi northeast | 2,300 ft | Excellent — the lowest scan sees close to the ground |

| KMUX San Francisco, CA | 138 mi south | 16,000 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.
