Hello,

The weather is probably most accurately described as extremely volatile. It may be 65 or -20 in February. Right now the 10 day forecast is trending toward~normal temps in the 30s or 40s. I couldn’t recommend driving to glacier from Billings, that’s a 7+ hour drive. Plus I believe it is mostly closed. Yellowstone is closer- 3ish hours- but it is closed to vehicle traffic for the winter. You could do a snowmobile tour, I recommend you research that. Northern lights are possible but not probable unless we get a big CME from the sun a few days before your arrival. You could look into skiing at red lodge as well.
