Which radars cover Dewey?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 57 miles west-southwest. 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 Dewey | View |
|---|---|---|---|
| KILX Lincoln, IL | 57 mi west-southwest | 4,200 ft | Good — most storms and steady rain or snow show clearly |
| KLOT Chicago, IL | 89 mi north | 8,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIND Indianapolis, IN | 114 mi east-southeast | 11,800 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.
