A pattern change is underway for the Northern Rockies, with cool and wet conditions coming this week. The coolest temperatures will occur on Thursday and Friday, with valley high temperatures in the 50s and 60s. Elevations above 6000 feet will see highs in the 40s. Rain will accompany the cooler temperatures in the valleys, and elevations above about 6500 feet will see wet snow. Cool overnight periods will bring the threat of frost down to the valley floors. If you're heading into the backcountry later this week, be prepared for cold and wet weather at all elevations, along with snow in the higher terrain.
Late this week we are transitioning to cooler weather, which is setting us up for an extended period of cool, wet, and raw conditions in the backcountry to start October. Hypothermia for those in the backcountry is the main concern, so if you plan on going out, be prepared for adverse weather!
