Which radars cover Latham?
The closest NEXRAD Doppler radar is KILX (Lincoln, IL), about 16 miles northwest. 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 Latham | View |
|---|---|---|---|
| KILX Lincoln, IL | 16 mi northwest | 800 ft | Excellent — the lowest scan sees close to the ground |
| KLSX St. Louis, MO | 120 mi southwest | 12,600 ft | Limited — the beam overshoots the lowest part of storms |
| KLOT Chicago, IL | 126 mi north-northeast | 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.
