Which radars cover Arcanum?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 56 miles southeast. 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 Arcanum | View |
|---|---|---|---|
| KILN Wilmington, OH | 56 mi southeast | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KIND Indianapolis, IN | 94 mi west-southwest | 8,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 112 mi north-northwest | 11,400 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.
