Which radars cover Des Arc?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 98 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 Des Arc | View |
|---|---|---|---|
| KLSX St. Louis, MO | 98 mi north | 9,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPAH Paducah, KY | 104 mi east | 10,200 ft | Limited — the beam overshoots the lowest part of storms |
| KNQA Memphis, TN | 141 mi south-southeast | 16,300 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.
