Which radars cover Ontario?
The closest NEXRAD Doppler radar is KIWX (Fort Wayne, IN), about 29 miles southwest. 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 Ontario | View |
|---|---|---|---|
| KIWX Fort Wayne, IN | 29 mi southwest | 1,700 ft | Excellent — the lowest scan sees close to the ground |
| KGRR Grand Rapids, MI | 83 mi north | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDTX Detroit, MI | 120 mi northeast | 12,700 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.
