Which radars cover Decker?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 21 miles south-southwest. 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 Decker | View |
|---|---|---|---|
| KVWX Evansville, IN | 21 mi south-southwest | 1,200 ft | Excellent — the lowest scan sees close to the ground |
| KLVX Louisville, KY | 94 mi east-southeast | 8,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KIND Indianapolis, IN | 106 mi northeast | 10,500 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.
