Which radars cover Grand Ridge?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 46 miles east-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 Grand Ridge | View |
|---|---|---|---|
| KLOT Chicago, IL | 46 mi east-northeast | 3,200 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 80 mi south-southwest | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
