Which radars cover St. Leon?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 62 miles east. 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 St. Leon | View |
|---|---|---|---|
| KILN Wilmington, OH | 62 mi east | 4,700 ft | Good — most storms and steady rain or snow show clearly |
| KIND Indianapolis, IN | 76 mi west-northwest | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLVX Louisville, KY | 106 mi south-southwest | 10,400 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.
