Which radars cover La Harpe?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 74 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 La Harpe | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 74 mi north-northeast | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 91 mi east-southeast | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 131 mi south | 14,700 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.
