Which radars cover Oswego?
The closest NEXRAD Doppler radar is KCAE (Columbia, SC), about 48 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 Oswego | View |
|---|---|---|---|
| KCAE Columbia, SC | 48 mi west | 3,400 ft | Good — most storms and steady rain or snow show clearly |
| KCLX Charleston, SC | 103 mi south-southwest | 10,100 ft | Limited — the beam overshoots the lowest part of storms |
| KLTX Wilmington, NC | 106 mi east | 10,600 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.
