Which radars cover Decatur?

The closest NEXRAD Doppler radar is KFFC (Atlanta, GA), about 32 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 Decatur	View
KFFC Atlanta, GA	32 mi south-southwest	2,000 ft	Excellent — the lowest scan sees close to the ground
KJGX Robins AFB, GA	93 mi southeast	8,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMXX Maxwell AFB, AL	121 mi southwest	13,000 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.
