Which radars cover Preston Heights?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 8 miles north. 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 Preston Heights | View |
|---|---|---|---|
| KLOT Chicago, IL | 8 mi north | 400 ft | Excellent — the lowest scan sees close to the ground |
