Which radars cover Mount Vernon?
The closest NEXRAD Doppler radar is KCLE (Cleveland, OH), about 78 miles north-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 Mount Vernon | View |
|---|---|---|---|
| KCLE Cleveland, OH | 78 mi north-northeast | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILN Wilmington, OH | 98 mi southwest | 9,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPBZ Pittsburgh, PA | 119 mi east | 12,600 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.
