Which radars cover Potsdam?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 49 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 Potsdam | View |
|---|---|---|---|
| KILN Wilmington, OH | 49 mi southeast | 3,500 ft | Good — most storms and steady rain or snow show clearly |
| KIND Indianapolis, IN | 101 mi west | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 118 mi northwest | 12,300 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.
