Which radars cover Allentown?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 72 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 Allentown | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 72 mi southeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KBGM Binghamton, NY | 114 mi north-northwest | 11,800 ft | Limited — the beam overshoots the lowest part of storms |
| KDOX Dover AFB, DE | 122 mi south | 13,100 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.
