Which radars cover Alsey?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 61 miles south-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 Alsey	View
KLSX St. Louis, MO	61 mi south-southwest	4,700 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	71 mi northeast	5,800 ft	Good — most storms and steady rain or snow show clearly
KDVN Quad Cities, IA	142 mi north	16,600 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.
