Which radars cover Triumph?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 49 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 Triumph | View |
|---|---|---|---|
| KLOT Chicago, IL | 49 mi east | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 81 mi west | 7,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 95 mi south | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
