Which radars cover Grass Lake?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 49 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 Grass Lake | View |
|---|---|---|---|
| KDTX Detroit, MI | 49 mi northeast | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KGRR Grand Rapids, MI | 81 mi west-northwest | 7,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIWX Fort Wayne, IN | 99 mi southwest | 9,400 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.
