A cold front drops western Montana's highs into the 50s and 60s. Snow levels fall to 6,000 feet near Glacier, and frost may show Sunday.

Let's call the science straight. A strong cold front swept across western Montana Friday with gusty winds, showers and isolated thunderstorms, NBC Montana reports, and it's bringing a more fall-like feel for the weekend. Daytime highs in the 50s and 60s will be common as colder air filters in through Saturday and Sunday. Wind advisories covered the Missoula and Bitterroot valleys, the Flathead and Mission valleys and the Kootenai/Cabinet region through midnight Friday, with gusts up to 45 mph. Behind the front, snow levels fall to around 6,000 feet in the mountains, with a small chance of light snow on Logan Pass and the higher elevations of Glacier National Park. NBC Montana warns that anyone heading into Glacier's backcountry should be prepared for cold, wet and raw conditions, and that even light snow and rain can create a hypothermia risk when paired with gusty winds and chilly temperatures. Higher-elevation valleys and cold-prone areas such as Butte could see patchy frost as early as Sunday morning. Dry, breezy weather is expected for much of next week. Here's your weekend list: pack a warm layer and a rain shell for any hike, tell someone your route and when you'll be back, and cover tender plants or bring the pots inside Saturday night. A sunny September afternoon can fool you. The mountains keep their own calendar.
