In the above image, 10,000 foot elevation temperatures are forecast to be between 14f (-10c) and 26f (-3c), dipping to 10f (-12c) Sunday and Monday (29-30 September), and moisture is expected to be plentiful across the area under a strong low pressure system. Our partners at Bogus Basin Idaho, Revelstoke Mountain Resort in British Columbia, and Kingfisher Heli also in British Columbia, are expected to receive significant snowfall between the 26th and 30th of September, best snowfall at Revelstoke, moderate to even heavy for the higher elevations, but snow is expected to fall down to 4,000 feet across the region. I would not be surprised to see over a foot of snow in favored areas along the great divide/ northern Rocky Mountains, and upper elevations at Revelstoke. Tahoe will also see snow, resort bases to top elevations, possibly heavy. Wow, an amazing start, and early October is looking busy as well. More details are coming. Below are depictions of forecast snow and rain between Thursday afternoon and Monday morning... Meteorologist/ Chris Manly
