Which radars cover St. Mary?
The closest NEXRAD Doppler radar is KLVX (Louisville, KY), about 42 miles 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 St. Mary | View |
|---|---|---|---|
| KLVX Louisville, KY | 42 mi northwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
