Which radars cover Petersburg?
The closest NEXRAD Doppler radar is KMVX (Grand Forks, ND), about 46 miles southeast. 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 Petersburg | View |
|---|---|---|---|
| KMVX Grand Forks, ND | 46 mi southeast | 3,200 ft | Good — most storms and steady rain or snow show clearly |
| KMBX Minot AFB, ND | 134 mi west-northwest | 15,200 ft | Limited — the beam overshoots the lowest part of storms |
| KBIS Bismarck, ND | 155 mi west-southwest | 19,200 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.
