Which radars cover Nason?
The closest NEXRAD Doppler radar is KVWX (Evansville, IN), about 68 miles east. 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 Nason | View |
|---|---|---|---|
| KVWX Evansville, IN | 68 mi east | 5,400 ft | Good — most storms and steady rain or snow show clearly |
| KPAH Paducah, KY | 77 mi south | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KLSX St. Louis, MO | 100 mi west-northwest | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
