Which radars cover Louisville?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 55 miles 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 Louisville | View |
|---|---|---|---|
| KVWX Evansville, IN | 55 mi southeast | 4,100 ft | Good — most storms and steady rain or snow show clearly |
| KILX Lincoln, IL | 105 mi north-northwest | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 117 mi west | 12,300 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.
