Which radars cover Leon Valley?
The closest NEXRAD Doppler radar is KEWX (San Antonio, TX), about 38 miles east-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 Leon Valley | View |
|---|---|---|---|
| KEWX San Antonio, TX | 38 mi east-northeast | 2,500 ft | Excellent — the lowest scan sees close to the ground |
| KDFX Laughlin AFB, TX | 101 mi west | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KGRK Central Texas, TX | 112 mi northeast | 11,500 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.
