Which radars cover Lake Hiawatha?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 65 miles south. 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 Lake Hiawatha | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 65 mi south | 5,100 ft | Good — most storms and steady rain or snow show clearly |
| KOKX Upton, NY | 79 mi east | 6,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KENX Albany, NY | 119 mi north | 12,600 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.
