Which radars cover Lewisville?
The closest NEXRAD Doppler radar is KSHV (Shreveport, LA), about 65 miles south-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 Lewisville | View |
|---|---|---|---|
| KSHV Shreveport, LA | 65 mi south-southwest | 5,100 ft | Good — most storms and steady rain or snow show clearly |
| KLZK Little Rock, AR | 127 mi northeast | 13,900 ft | Limited — the beam overshoots the lowest part of storms |
