Which radars cover Hemlock?
The closest NEXRAD Doppler radar is KILN (Wilmington, OH), about 90 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 Hemlock | View |
|---|---|---|---|
| KILN Wilmington, OH | 90 mi west | 8,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KRLX Charleston, WV | 92 mi south-southeast | 8,400 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KPBZ Pittsburgh, PA | 121 mi east-northeast | 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.
