Which radars cover Warrenton?

The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 26 miles east-southeast. 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 Warrenton	View
KLSX St. Louis, MO	26 mi east-southeast	1,500 ft	Excellent — the lowest scan sees close to the ground
KILX Lincoln, IL	133 mi northeast	15,000 ft	Limited — the beam overshoots the lowest part of storms
KSGF Springfield, MO	165 mi southwest	21,200 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.
