Which radars cover Lacon?

The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 60 miles south. 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 Lacon	View
KILX Lincoln, IL	60 mi south	4,600 ft	Good — most storms and steady rain or snow show clearly
KDVN Quad Cities, IA	73 mi northwest	6,100 ft	Fair — the beam can pass over shallow snow and low-level rotation
KLOT Chicago, IL	79 mi east-northeast	6,800 ft	Fair — the beam can pass over shallow snow and low-level rotation

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
