Which radars cover Avon?

The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 66 miles north. 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 Avon	View
KDVN Quad Cities, IA	66 mi north	5,200 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	68 mi east-southeast	5,400 ft	Good — most storms and steady rain or snow show clearly
KLSX St. Louis, MO	136 mi south	15,600 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.
