Which radars cover Gilman?

The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 58 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 Gilman	View
KLOT Chicago, IL	58 mi north	4,400 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	82 mi west-southwest	7,100 ft	Fair — the beam can pass over shallow snow and low-level rotation
KIND Indianapolis, IN	116 mi southeast	12,100 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.
