Which radars cover Oak Forest?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 17 miles west. 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 Oak Forest | View |
|---|---|---|---|
| KLOT Chicago, IL | 17 mi west | 900 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 103 mi north-northwest | 10,000 ft | Limited — the beam overshoots the lowest part of storms |
| KIWX Fort Wayne, IN | 108 mi east | 10,800 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.
