Which radars cover Carrollton?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 44 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 Carrollton	View
KLSX St. Louis, MO	44 mi south-southwest	3,000 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	82 mi northeast	7,100 ft	Fair — the beam can pass over shallow snow and low-level rotation
KDVN Quad Cities, IA	160 mi north	20,300 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.
