Which radars cover Clay?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 98 miles east. 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 Clay | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 98 mi east | 9,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 105 mi west-northwest | 10,300 ft | Limited — the beam overshoots the lowest part of storms |
| KDOX Dover AFB, DE | 105 mi south-southeast | 10,400 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.
