Which radars cover Merriam?
The closest NEXRAD Doppler radar is KEAX (Kansas City, MO), about 27 miles east-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 Merriam | View |
|---|---|---|---|
| KEAX Kansas City, MO | 27 mi east-southeast | 1,600 ft | Excellent — the lowest scan sees close to the ground |
| KTWX Topeka, KS | 83 mi west | 7,200 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KSGF Springfield, MO | 142 mi south-southeast | 16,600 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.
