Which radars cover Jefferson?
The closest NEXRAD Doppler radar is KLWX (Sterling, MD), about 27 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 Jefferson | View |
|---|---|---|---|
| KLWX Sterling, MD | 27 mi south | 1,600 ft | Excellent — the lowest scan sees close to the ground |
| KCCX State College, PA | 110 mi north-northwest | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
| KDOX Dover AFB, DE | 119 mi east-southeast | 12,500 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.
