Which radars cover Brockton?
The closest NEXRAD Doppler radar is KGGW (Glasgow, MT), about 79 miles west. 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 Brockton | View |
|---|---|---|---|
| KGGW Glasgow, MT | 79 mi west | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KMBX Minot AFB, ND | 186 mi east | 26,000 ft | Limited — the beam overshoots the lowest part of storms |
| KBIS Bismarck, ND | 216 mi east-southeast | 33,300 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.
