Which radars cover Plymouth?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 84 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 Plymouth | View |
|---|---|---|---|
| KILX Lincoln, IL | 84 mi east | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 93 mi north | 8,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 111 mi south | 11,200 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.
