Which radars cover Collinsville?
The closest NEXRAD Doppler radar is KOKX (Upton, NY), about 66 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 Collinsville | View |
|---|---|---|---|
| KOKX Upton, NY | 66 mi south | 5,200 ft | Good — most storms and steady rain or snow show clearly |
