Which radars cover Riverton?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 24 miles north-northeast. 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 Riverton | View |
|---|---|---|---|
| KILX Lincoln, IL | 24 mi north-northeast | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KLSX St. Louis, MO | 100 mi southwest | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 134 mi north-northwest | 15,100 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.
