Which radars cover Atglen?
The closest NEXRAD Doppler radar is KDOX (Dover AFB, DE), about 83 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 Atglen | View |
|---|---|---|---|
| KDOX Dover AFB, DE | 83 mi south-southeast | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDIX Philadelphia, NJ | 83 mi east | 7,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLWX Sterling, MD | 105 mi southwest | 10,300 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.
