Which radars cover Meredosia?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 68 miles east-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 Meredosia | View |
|---|---|---|---|
| KILX Lincoln, IL | 68 mi east-northeast | 5,500 ft | Good — most storms and steady rain or snow show clearly |
| KLSX St. Louis, MO | 79 mi south | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDVN Quad Cities, IA | 123 mi north | 13,200 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.
