Which radars cover New Haven?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 30 miles east-northeast. 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 New Haven | View |
|---|---|---|---|
| KLSX St. Louis, MO | 30 mi east-northeast | 1,800 ft | Excellent — the lowest scan sees close to the ground |
| KILX Lincoln, IL | 147 mi northeast | 17,500 ft | Limited — the beam overshoots the lowest part of storms |
| KSGF Springfield, MO | 152 mi southwest | 18,600 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.
