Which radars cover Rockville?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 68 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 Rockville | View |
|---|---|---|---|
| KBOX Boston, MA | 68 mi east | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KOKX Upton, NY | 72 mi south-southwest | 6,000 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 96 mi west-northwest | 9,100 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.
