Which radars cover Granville?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 64 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 Granville | View |
|---|---|---|---|
| KLOT Chicago, IL | 64 mi east-northeast | 5,000 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 74 mi west-northwest | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 77 mi south | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
