Which radars cover Ontario?
The closest NEXRAD Doppler radar is KCLE (Cleveland, OH), about 59 miles 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 Ontario | View |
|---|---|---|---|
| KCLE Cleveland, OH | 59 mi northeast | 4,500 ft | Good — most storms and steady rain or snow show clearly |
| KILN Wilmington, OH | 113 mi southwest | 11,600 ft | Limited — the beam overshoots the lowest part of storms |
| KPBZ Pittsburgh, PA | 127 mi east | 13,900 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.
