Which radars cover South Plainfield?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 43 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 South Plainfield | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 43 mi south | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KOKX Upton, NY | 84 mi east-northeast | 7,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 133 mi south-southwest | 14,900 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.
