Which radars cover Mount Vernon?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 51 miles east. 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 |
|---|---|---|---|
| KOKX Upton, NY | 51 mi east | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KDIX Philadelphia, NJ | 73 mi south-southwest | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 116 mi north | 12,100 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.
