Which radars cover Andover?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 74 miles south-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 Andover | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 74 mi south-southeast | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOKX Upton, NY | 99 mi east | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBGM Binghamton, NY | 106 mi northwest | 10,400 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.
