Which radars cover Pontoosuc?
The closest NEXRAD Doppler radar is KDVN (Quad Cities, IA), about 75 miles north-northeast. 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 Pontoosuc | View |
|---|---|---|---|
| KDVN Quad Cities, IA | 75 mi north-northeast | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 104 mi east-southeast | 10,200 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 136 mi south-southeast | 15,600 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.
