Which radars cover Seneca?

The closest NEXRAD Doppler radar is KTWX (Topeka, KS), about 59 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 Seneca	View
KTWX Topeka, KS	59 mi south	4,400 ft	Good — most storms and steady rain or snow show clearly
KOAX Omaha, NE	104 mi north	10,100 ft	Limited — the beam overshoots the lowest part of storms
KEAX Kansas City, MO	120 mi southeast	12,700 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.
