Which radars cover Brooklyn?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 28 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 Brooklyn | View |
|---|---|---|---|
| KLSX St. Louis, MO | 28 mi west | 1,700 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 112 mi north-northeast | 11,500 ft | Limited — the beam overshoots the lowest part of storms |
| KPAH Paducah, KY | 133 mi southeast | 15,100 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.
