Which radars cover Dayton?

The closest NEXRAD Doppler radar is KBMX (Birmingham, AL), about 76 miles northeast. 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 Dayton	View
KBMX Birmingham, AL	76 mi northeast	6,400 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMXX Maxwell AFB, AL	109 mi east	10,900 ft	Limited — the beam overshoots the lowest part of storms
KGWX Columbus AFB, MS	114 mi north-northwest	11,800 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.
