Which radars cover Terre du Lac?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 55 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 Terre du Lac | View |
|---|---|---|---|
| KLSX St. Louis, MO | 55 mi north | 4,000 ft | Good — most storms and steady rain or snow show clearly |
| KPAH Paducah, KY | 117 mi east-southeast | 12,200 ft | Limited — the beam overshoots the lowest part of storms |
| KSGF Springfield, MO | 159 mi west-southwest | 20,000 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.
