Which radars cover Casco?
The closest NEXRAD Doppler radar is KGRB (Green Bay, WI), about 24 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 Casco | View |
|---|---|---|---|
| KGRB Green Bay, WI | 24 mi west | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 119 mi south-southwest | 12,600 ft | Limited — the beam overshoots the lowest part of storms |
| KMQT Marquette, MI | 137 mi north | 15,600 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.
