Which radars cover Califon?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 58 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 Califon | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 58 mi south-southeast | 4,300 ft | Good — most storms and steady rain or snow show clearly |
| KOKX Upton, NY | 104 mi east | 10,200 ft | Limited — the beam overshoots the lowest part of storms |
| KBGM Binghamton, NY | 118 mi north-northwest | 12,500 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.
