Post From Friday, June 7th:
A cold Low-pressure system will be moving across the Pacific Northwest & Northern Rockies Friday & Saturday, June 7th & 8th. This will bring some rain, a few thunderstorms, and a mix of rain and snow to the mountains of Northwest Wyoming. A cold front is currently stalled over central Idaho, but it will progress eastward the next 24-hours.

Yellowstone National Park will see more significant accumulations of snow late Friday night/early Saturday morning. As well as, the Beartooth Mountains of Southwest Montana. Lesser amounts in the Tetons, Wind Rivers, & Bighorns of Wyoming. Snow levels will be low enough to possibly create a mix of rain and snow in Jackson Hole.
