Which radars cover Altona?

The closest NEXRAD Doppler radar is KIWX (Fort Wayne, IN), about 28 miles west. 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 Altona	View
KIWX Fort Wayne, IN	28 mi west	1,700 ft	Excellent — the lowest scan sees close to the ground
KGRR Grand Rapids, MI	108 mi north	10,900 ft	Limited — the beam overshoots the lowest part of storms
KDTX Detroit, MI	127 mi northeast	13,900 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.
