Which radars cover Lake Tekakwitha?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 18 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 Lake Tekakwitha | View |
|---|---|---|---|
| KLSX St. Louis, MO | 18 mi north | 1,000 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 139 mi north-northeast | 16,100 ft | Limited — the beam overshoots the lowest part of storms |
| KPAH Paducah, KY | 143 mi southeast | 16,700 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.
