Which radars cover Harrison?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 53 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 Harrison | View |
|---|---|---|---|
| KILN Wilmington, OH | 53 mi east-northeast | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KIND Indianapolis, IN | 86 mi west-northwest | 7,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLVX Louisville, KY | 108 mi southwest | 10,900 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.
