Which radars cover Colp?
The closest NEXRAD Doppler radar is KPAH (Paducah, KY), about 54 miles south-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 Colp | View |
|---|---|---|---|
| KPAH Paducah, KY | 54 mi south-southeast | 3,900 ft | Good — most storms and steady rain or snow show clearly |
| KVWX Evansville, IN | 80 mi east-northeast | 6,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 107 mi northwest | 10,600 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.
