Which radars cover Onarga?

The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 62 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 Onarga	View
KLOT Chicago, IL	62 mi north	4,700 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	80 mi west-southwest	6,900 ft	Fair — the beam can pass over shallow snow and low-level rotation
KIND Indianapolis, IN	115 mi southeast	11,900 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.
