Which radars cover Riverdale?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 73 miles south. 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 Riverdale | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 73 mi south | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOKX Upton, NY | 76 mi east | 6,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 111 mi north | 11,200 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.
