Which radars cover Napoleon?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 54 miles 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 Napoleon | View |
|---|---|---|---|
| KDTX Detroit, MI | 54 mi northeast | 3,900 ft | Good — most storms and steady rain or snow show clearly |
| KGRR Grand Rapids, MI | 83 mi northwest | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 93 mi southwest | 8,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
