Which radars cover Maplewood?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 20 miles west-northwest. 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 Maplewood | View |
|---|---|---|---|
| KLSX St. Louis, MO | 20 mi west-northwest | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 119 mi north-northeast | 12,500 ft | Limited — the beam overshoots the lowest part of storms |
| KPAH Paducah, KY | 136 mi southeast | 15,600 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.
