Which radars cover Iola?
The closest NEXRAD Doppler radar is KGRK (Central Texas, TX), about 78 miles west. 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 Iola | View |
|---|---|---|---|
| KGRK Central Texas, TX | 78 mi west | 6,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KHGX Houston, TX | 108 mi southeast | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
| KEWX San Antonio, TX | 138 mi west-southwest | 15,900 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.
