Which radars cover Ursa?
The closest NEXRAD Doppler radar is KLSX (St. Louis, MO), about 102 miles south-southeast. 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 Ursa | View |
|---|---|---|---|
| KLSX St. Louis, MO | 102 mi south-southeast | 9,900 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KILX Lincoln, IL | 108 mi east | 10,800 ft | Limited — the beam overshoots the lowest part of storms |
| KDVN Quad Cities, IA | 114 mi north-northeast | 11,800 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.
