Which radars cover Williston?
The closest NEXRAD Doppler radar is KDOX (Dover AFB, DE), about 22 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 Williston | View |
|---|---|---|---|
| KDOX Dover AFB, DE | 22 mi east | 1,300 ft | Excellent — the lowest scan sees close to the ground |
| KLWX Sterling, MD | 89 mi west | 8,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDIX Philadelphia, NJ | 109 mi northeast | 11,000 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.
