Which radars cover Blawnox?
The closest NEXRAD Doppler radar is KPBZ (Pittsburgh, PA), about 19 miles west. 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 Blawnox | View |
|---|---|---|---|
| KPBZ Pittsburgh, PA | 19 mi west | 1,100 ft | Excellent — the lowest scan sees close to the ground |
| KCCX State College, PA | 102 mi east-northeast | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCLE Cleveland, OH | 122 mi west-northwest | 13,100 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.
