Which radars cover Mertens?
The closest NEXRAD Doppler radar is KFWS (Dallas/Fort Worth, TX), about 43 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 Mertens | View |
|---|---|---|---|
| KFWS Dallas/Fort Worth, TX | 43 mi northwest | 2,900 ft | Excellent — the lowest scan sees close to the ground |
| KGRK Central Texas, TX | 97 mi south-southwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDYX Dyess AFB, TX | 142 mi west-northwest | 16,600 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.
