Which radars cover Sleepy Hollow?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 36 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 Sleepy Hollow | View |
|---|---|---|---|
| KLOT Chicago, IL | 36 mi south-southeast | 2,300 ft | Excellent — the lowest scan sees close to the ground |

| KDVN Quad Cities, IA | 121 mi west-southwest | 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.
