Which radars cover Seaton?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 37 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 Seaton | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 37 mi north-northeast | 2,400 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 101 mi southeast | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 145 mi east-northeast | 17,200 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.
