Which radars cover Logan?
The closest NEXRAD Doppler radar is KTFX (Great Falls, MT), about 109 miles north. 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 Logan | View |
|---|---|---|---|
| KTFX Great Falls, MT | 109 mi north | 11,000 ft | Limited — the beam overshoots the lowest part of storms |
