Which radars cover Dayton?
The closest NEXRAD Doppler radar is KMPX (Minneapolis, MN), about 24 miles south. 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 Dayton | View |
|---|---|---|---|
| KMPX Minneapolis, MN | 24 mi south | 1,400 ft | Excellent — the lowest scan sees close to the ground |
| KDLH Duluth, MN | 129 mi north-northeast | 14,300 ft | Limited — the beam overshoots the lowest part of storms |
| KARX La Crosse, WI | 147 mi southeast | 17,500 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.
