Which radars cover Decatur?
The closest NEXRAD Doppler radar is KIWX (Fort Wayne, IN), about 54 miles northwest. 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 Decatur | View |
|---|---|---|---|
| KIWX Fort Wayne, IN | 54 mi northwest | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KIND Indianapolis, IN | 105 mi southwest | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KILN Wilmington, OH | 114 mi south-southeast | 11,700 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.
