Which radars cover Heidelberg?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 25 miles north. 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 Heidelberg | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 25 mi north | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KARX La Crosse, WI | 129 mi east-southeast | 14,300 ft | Limited — the beam overshoots the lowest part of storms |
| KFSD Sioux Falls, SD | 166 mi west-southwest | 21,500 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.
