Which radars cover Herkimer?
The closest NEXRAD Doppler radar is KTWX (Topeka, KS), about 67 miles south-southeast. 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 Herkimer | View |
|---|---|---|---|
| KTWX Topeka, KS | 67 mi south-southeast | 5,300 ft | Good — most storms and steady rain or snow show clearly |
| KUEX Hastings, NE | 96 mi west-northwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KOAX Omaha, NE | 100 mi north | 9,600 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
