Which radars cover Grand Tower?
The closest NEXRAD Doppler radar is KPAH (Paducah, KY), about 57 miles southeast. 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 Grand Tower | View |
|---|---|---|---|
| KPAH Paducah, KY | 57 mi southeast | 4,200 ft | Good — most storms and steady rain or snow show clearly |
| KLSX St. Louis, MO | 97 mi northwest | 9,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KVWX Evansville, IN | 106 mi east-northeast | 10,500 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.
