Which radars cover Deer Grove?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 46 miles west. 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 Deer Grove | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 46 mi west | 3,200 ft | Good — most storms and steady rain or snow show clearly |
| KLOT Chicago, IL | 83 mi east | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 103 mi south | 10,000 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.
