Which radars cover Princeton?

The closest NEXRAD Doppler radar is KDMX (Des Moines, IA), about 93 miles north. 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 Princeton	View
KDMX Des Moines, IA	93 mi north	8,500 ft	Fair — the beam can pass over shallow snow and low-level rotation
KEAX Kansas City, MO	115 mi south-southwest	12,000 ft	Limited — the beam overshoots the lowest part of storms
KOAX Omaha, NE	159 mi west-northwest	19,900 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.
