Which radars cover Como?

The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 43 miles west-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 Como	View
KDVN Quad Cities, IA	43 mi west-southwest	2,900 ft	Excellent — the lowest scan sees close to the ground
KLOT Chicago, IL	87 mi east	7,900 ft	Fair — the beam can pass over shallow snow and low-level rotation
KMKX Milwaukee/Sullivan, WI	104 mi northeast	10,100 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.
