Which radars cover Katonah?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 51 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 Katonah | View |
|---|---|---|---|
| KOKX Upton, NY | 51 mi east-southeast | 3,600 ft | Good — most storms and steady rain or snow show clearly |
| KENX Albany, NY | 94 mi north-northwest | 8,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDIX Philadelphia, NJ | 98 mi south-southwest | 9,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
