Which radars cover Ravanna?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 89 miles north. 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 Ravanna | View |
|---|---|---|---|
| KDMX Des Moines, IA | 89 mi north | 8,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KEAX Kansas City, MO | 122 mi south-southwest | 13,000 ft | Limited — the beam overshoots the lowest part of storms |
| KOAX Omaha, NE | 163 mi west-northwest | 20,900 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.
