Which radars cover Port Chester?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 43 miles east-southeast. 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 Port Chester | View |
|---|---|---|---|
| KOKX Upton, NY | 43 mi east-southeast | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KDIX Philadelphia, NJ | 83 mi south-southwest | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 111 mi north | 11,300 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.
