Which radars cover Williamsburg?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 74 miles east. 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 Williamsburg | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 74 mi east | 6,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 88 mi west | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KARX La Crosse, WI | 155 mi north-northeast | 19,100 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.
