Which radars cover Wilmington?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 55 miles south. 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 Wilmington	View
KLSX St. Louis, MO	55 mi south	4,000 ft	Good — most storms and steady rain or snow show clearly
KILX Lincoln, IL	77 mi northeast	6,500 ft	Fair — the beam can pass over shallow snow and low-level rotation
KDVN Quad Cities, IA	147 mi north	17,600 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.
