Which radars cover Jacobus?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 75 miles south-southwest. 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 Jacobus | View |
|---|---|---|---|
| KLWX Sterling, MD | 75 mi south-southwest | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCCX State College, PA | 99 mi northwest | 9,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDOX Dover AFB, DE | 100 mi southeast | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
