Which radars cover Aviston?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 58 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 Aviston	View
KLSX St. Louis, MO	58 mi west	4,300 ft	Good — most storms and steady rain or snow show clearly
KVWX Evansville, IN	105 mi east-southeast	10,400 ft	Limited — the beam overshoots the lowest part of storms
KILX Lincoln, IL	106 mi north	10,600 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.
