Which radars cover Truro?
The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 37 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 Truro | View |
|---|---|---|---|
| KDMX Des Moines, IA | 37 mi north | 2,400 ft | Excellent — the lowest scan sees close to the ground |
| KOAX Omaha, NE | 131 mi west | 14,600 ft | Limited — the beam overshoots the lowest part of storms |
| KEAX Kansas City, MO | 167 mi south | 21,700 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.
