Helena is in the middle of a stretch of genuinely nice fall weather, and forecasters say it'll hold through Thursday. An upper-level ridge sitting over the region is keeping skies mostly sunny and temperatures comfortable — the kind of October days that make you remember why people choose to live here.
The good news ends Thursday night. A strong cold front tied to an upper-level trough is expected to push through, bringing significantly cooler temperatures, gusty to strong winds, and rain at valley level with snow in the mountains. Friday looks like the first real taste of winter conditions for the season.
If you've been putting off a hike up Mount Helena or a drive through the canyon to catch the fall color, this week is your window. The forecast is a reminder that Helena's shoulder season doesn't linger — when it turns, it turns fast.
