Snow is falling over the higher elevations, as an upper-level low swirls over the Northern Rockies. Alta, Utah reported nine inches of snow on Tuesday, which makes it their third highest one-day snowfall total in June. Lake-effect rain and snow has also developed off the Great Salt Lake, with snow above 7,000 feet.
Mountain snow will continue through Wednesday night or Thursday morning in parts of the Northern Rockies. Winds will gust up to 30 mph and visibility may be less than half a mile at times. Snow levels will drop to 6,500 feet through Wednesday, where winter storm warnings are in place. Winter weather advisories are also posted for the Tetons and the Wasatch Mountains.
Closer to pass level, look for a mix of rain and snow, with no accumulation expected. But if you have an early summer vacation planned for Glacier National Park, remember to bring your snow gear as more than a foot of snow is not out of the question.
