What this score means
The 0–100 number is our viewing score, not a percent chance. It combines NOAA signals with NWS clouds, darkness, moonlight and Montana regional thresholds.
Montana Regional Outlook
Northern Montana can see aurora during moderate geomagnetic activity, while Glacier adds exceptionally dark protected skies and open northern views.
How to use this tonight
Glacier is the benchmark; compare Whitefish/Flathead, the Hi-Line and Fort Peck when clouds vary across the state. Southern cities generally need a stronger geomagnetic push.

Data and truth boundaries
OVATION is a modeled short-term aurora signal and Kp is broad geomagnetic context. Neither is a sighting probability. Missing values stay missing.
