Which radars cover Dieterich?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 66 miles south-southeast. 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 Dieterich | View |
|---|---|---|---|
| KVWX Evansville, IN | 66 mi south-southeast | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 91 mi north-northwest | 8,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIND Indianapolis, IN | 121 mi east-northeast | 12,900 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.
