Which radars cover St. Bonaventure?

The closest NEXRAD Doppler radar is KBUF (Buffalo, NY), about 62 miles north-northwest. 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 St. Bonaventure	View
KBUF Buffalo, NY	62 mi north-northwest	4,700 ft	Good — most storms and steady rain or snow show clearly
KCCX State College, PA	84 mi south-southeast	7,300 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBGM Binghamton, NY	128 mi east	14,100 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.
