Which radars cover Irmo?

The closest NEXRAD Doppler radar is KCAE (Columbia, SC), about 11 miles south-southeast. 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 Irmo	View
KCAE Columbia, SC	11 mi south-southeast	600 ft	Excellent — the lowest scan sees close to the ground
KGSP Greer, SC	79 mi northwest	6,800 ft	Fair — the beam can pass over shallow snow and low-level rotation
KCLX Charleston, SC	100 mi south	9,700 ft	Fair — the beam can pass over shallow snow and low-level rotation

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
