Which radars cover Marion?
The closest NEXRAD Doppler radar is KEWX (San Antonio, TX), about 11 miles northeast. 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 Marion | View |
|---|---|---|---|
| KEWX San Antonio, TX | 11 mi northeast | 600 ft | Excellent — the lowest scan sees close to the ground |
| KGRK Central Texas, TX | 91 mi north-northeast | 8,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCRP Corpus Christi, TX | 129 mi south-southeast | 14,300 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.
