Which radars cover Harmony?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 67 miles 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 Harmony | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 67 mi southeast | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KBGM Binghamton, NY | 109 mi north-northwest | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
| KOKX Upton, NY | 119 mi east | 12,600 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.
