Which radars cover Griggstown?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 35 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 Griggstown | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 35 mi south-southeast | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KOKX Upton, NY | 96 mi east-northeast | 9,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 120 mi south-southwest | 12,800 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.
