Weather Discussion & Outlook

Some some clouds & snow showers hanging around over western Wyoming today, tonight, & Saturday with light accumulations. Then Saturday night the jet stream out in the Pacific punches further inland and carries more moisture over us, with more snowfall for the mountains along with some very strong winds. Temps will warm enough during the day Sunday for rain to mix with snow in the valley, so I held snow accumulations down a bit. But the mountains, will get significant accumulations, along with the wind, avalanche danger will rise over the weekend (Check jhavalanche.org for latest avalanche forecast.) Jet still overhead in a NW flow Monday, but cooling temps and less moisture. Drier by Monday night and winds drop off Tuesday, with a drier NW flow Tuesday into Wednesday. The next storm moves across the Pacific Northwest Wednesday and should bring more snow Christmas Eve & Christmas morning, with cooler air & drier weather later Christmas Day and for Friday.
