Which radars cover Marathon?

The closest NEXRAD Doppler radar is KBGM (Binghamton, NY), about 17 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 Marathon	View
KBGM Binghamton, NY	17 mi south	900 ft	Excellent — the lowest scan sees close to the ground
KTYX Montague, NY	92 mi north	8,500 ft	Fair — the beam can pass over shallow snow and low-level rotation
KENX Albany, NY	101 mi east	9,700 ft	Fair — the beam can pass over shallow snow and low-level rotation

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
