Which radars cover Joslin?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 19 miles west-northwest. 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 Joslin | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 19 mi west-northwest | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 107 mi south-southeast | 10,600 ft | Limited — the beam overshoots the lowest part of storms |
| KLOT Chicago, IL | 111 mi east | 11,200 ft | Limited — the beam overshoots the lowest part of storms |
