Which radars cover Clark?

The closest NEXRAD Doppler radar is KPBZ (Pittsburgh, PA), about 53 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.

RadarDistanceLowest beam over ClarkView
KPBZ
Pittsburgh, PA		53 mi south3,900 ftGood — most storms and steady rain or snow show clearly
KCLE
Cleveland, OH		76 mi west6,400 ftFair — the beam can pass over shallow snow and low-level rotation
KCCX
State College, PA		128 mi east14,000 ftLimited — 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.
