Which radars cover Allison Park?
The closest NEXRAD Doppler radar is KPBZ (Pittsburgh, PA), about 14 miles west-southwest. 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 Allison Park | View |
|---|---|---|---|
| KPBZ Pittsburgh, PA | 14 mi west-southwest | 700 ft | Excellent — the lowest scan sees close to the ground |
| KCCX State College, PA | 105 mi east-northeast | 10,400 ft | Limited — the beam overshoots the lowest part of storms |
| KCLE Cleveland, OH | 115 mi west-northwest | 11,900 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.
