Which radars cover Afton?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 37 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 Afton | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 37 mi west | 2,400 ft | Excellent — the lowest scan sees close to the ground |
| KARX La Crosse, WI | 110 mi southeast | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
| KDLH Duluth, MN | 137 mi north-northeast | 15,700 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.
