Which radars cover Seymour?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 11 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 Seymour | View |
|---|---|---|---|
| KGRB Green Bay, WI | 11 mi east | 600 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 107 mi south | 10,700 ft | Limited — the beam overshoots the lowest part of storms |
| KMQT Marquette, MI | 144 mi north-northeast | 17,100 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.
