Which radars cover Boulder Hill?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 15 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 Boulder Hill | View |
|---|---|---|---|
| KLOT Chicago, IL | 15 mi east-southeast | 800 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 88 mi north | 7,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 116 mi west | 12,100 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.
