Which radars cover Ollie?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 83 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 Ollie | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 83 mi east-northeast | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 92 mi west-northwest | 8,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 162 mi east-southeast | 20,500 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.
