Which radars cover Suwanee?

The closest NEXRAD Doppler radar is KFFC (Atlanta, GA), about 56 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 Suwanee	View
KFFC Atlanta, GA	56 mi south-southwest	4,100 ft	Good — most storms and steady rain or snow show clearly
KJGX Robins AFB, GA	104 mi south-southeast	10,100 ft	Limited — the beam overshoots the lowest part of storms
KGSP Greer, SC	120 mi east-northeast	12,700 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.
