Which radars cover Portville?
The closest NEXRAD Doppler radar is KBUF (Buffalo, NY), about 66 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 Portville | View |
|---|---|---|---|
| KBUF Buffalo, NY | 66 mi north-northwest | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| KCCX State College, PA | 79 mi south-southeast | 6,700 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBGM Binghamton, NY | 121 mi east | 12,900 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.
