Which radars cover St. Catharine?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 96 miles southwest. 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 St. Catharine | View |
|---|---|---|---|
| KEAX Kansas City, MO | 96 mi southwest | 9,100 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KDMX Des Moines, IA | 139 mi north-northwest | 16,000 ft | Limited — the beam overshoots the lowest part of storms |
| KLSX St. Louis, MO | 145 mi east-southeast | 17,200 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.
