Which radars cover Big Spring?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 44 miles east. 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 Big Spring | View |
|---|---|---|---|
| KLSX St. Louis, MO | 44 mi east | 3,000 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 148 mi northeast | 17,800 ft | Limited — the beam overshoots the lowest part of storms |
| KEAX Kansas City, MO | 150 mi west | 18,100 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.
