Which radars cover Bartlett?
The closest NEXRAD Doppler radar is KLOT (Chicago, IL), about 25 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 Bartlett | View |
|---|---|---|---|
| KLOT Chicago, IL | 25 mi south | 1,500 ft | Excellent — the lowest scan sees close to the ground |
| KMKX Milwaukee/Sullivan, WI | 72 mi north-northwest | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KDVN Quad Cities, IA | 126 mi west | 13,800 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.
