Which radars cover Allen?
The closest NEXRAD Doppler radar is KFWS (Dallas/Fort Worth, TX), about 52 miles southwest. 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 Allen | View |
|---|---|---|---|
| KFWS Dallas/Fort Worth, TX | 52 mi southwest | 3,800 ft | Good — most storms and steady rain or snow show clearly |
| KDYX Dyess AFB, TX | 155 mi west-southwest | 19,200 ft | Limited — the beam overshoots the lowest part of storms |
| KTLX Oklahoma City, OK | 158 mi north-northwest | 19,700 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.
