Which radars cover Sun Prairie?
The closest NEXRAD Doppler radar is KTFX (Great Falls, MT), about 7 miles 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 Sun Prairie | View |
|---|---|---|---|
| KTFX Great Falls, MT | 7 mi southeast | 400 ft | Excellent — the lowest scan sees close to the ground |
| KMSX Missoula, MT | 122 mi west-southwest | 13,100 ft | Limited — the beam overshoots the lowest part of storms |
| KBLX Billings, MT | 179 mi southeast | 24,300 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.
