Which radars cover Big Run?

The closest NEXRAD Doppler radar is KCCX (State College, PA), about 46 miles east. 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 Big Run	View
KCCX State College, PA	46 mi east	3,200 ft	Good — most storms and steady rain or snow show clearly
KPBZ Pittsburgh, PA	76 mi west-southwest	6,400 ft	Fair — the beam can pass over shallow snow and low-level rotation
KBUF Buffalo, NY	137 mi north	15,700 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.
