Which radars cover South Lyon?
The closest NEXRAD Doppler radar is KDTX (Detroit, MI), about 19 miles north-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 South Lyon | View |
|---|---|---|---|
| KDTX Detroit, MI | 19 mi north-northeast | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KGRR Grand Rapids, MI | 101 mi west-northwest | 9,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCLE Cleveland, OH | 117 mi southeast | 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.
