Which radars cover Long Grove?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 6 miles south. 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 Long Grove | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 6 mi south | 300 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 125 mi south-southeast | 13,500 ft | Limited — the beam overshoots the lowest part of storms |
| KLOT Chicago, IL | 129 mi east | 14,300 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.
