Which radars cover Iron Mountain Lake?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 70 miles north. 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 Iron Mountain Lake | View |
|---|---|---|---|
| KLSX St. Louis, MO | 70 mi north | 5,600 ft | Good — most storms and steady rain or snow show clearly |
| KPAH Paducah, KY | 110 mi east-southeast | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
| KSGF Springfield, MO | 156 mi west | 19,300 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.
