Which radars cover St. Louis?
The closest NEXRAD Doppler radar is KGRR (Grand Rapids, MI), about 59 miles southwest. 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 St. Louis | View |
|---|---|---|---|
| KGRR Grand Rapids, MI | 59 mi southwest | 4,500 ft | Good — most storms and steady rain or snow show clearly |
| KDTX Detroit, MI | 76 mi southeast | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KAPX Gaylord, MI | 104 mi north | 10,100 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.
