Which radars cover Marengo?

The closest NEXRAD Doppler radar is KCLE (Cleveland, OH), about 86 miles northeast. 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 Marengo	View
KCLE Cleveland, OH	86 mi northeast	7,600 ft	Fair — the beam can pass over shallow snow and low-level rotation
KILN Wilmington, OH	86 mi southwest	7,700 ft	Fair — the beam can pass over shallow snow and low-level rotation
KPBZ Pittsburgh, PA	137 mi east	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.
