Which radars cover Constantine?
The closest NEXRAD Doppler radar is KIWX (Fort Wayne, IN), about 33 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 Constantine | View |
|---|---|---|---|
| KIWX Fort Wayne, IN | 33 mi south | 2,100 ft | Excellent — the lowest scan sees close to the ground |
| KGRR Grand Rapids, MI | 73 mi north | 6,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLOT Chicago, IL | 126 mi west | 13,700 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.
