Which radars cover Grantville?
The closest NEXRAD Doppler radar is KTWX (Topeka, KS), about 36 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 Grantville | View |
|---|---|---|---|
| KTWX Topeka, KS | 36 mi west | 2,300 ft | Excellent — the lowest scan sees close to the ground |
| KEAX Kansas City, MO | 72 mi east-southeast | 5,900 ft | Good — most storms and steady rain or snow show clearly |
| KICT Wichita, KS | 142 mi southwest | 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.
