Showers will linger through Thursday morning across Jackson Hole before tapering off in the afternoon. The next storm will then arrive early Friday morning with periods of rain and snow continuing off-and-on through Saturday afternoon. The higher elevations are going to see a heavy late-season snow event with a good soaking rain for the valley.
Off-and-on showers will linger through midday Thursday before tapering off to isolated sprinkles in the afternoon. The higher elevations could pick up another inch or two of snow on Thursday morning. Otherwise, Thursday will be a chilly day with mostly cloudy skies and highs in the low 50s.
A strong storm system will arrive early on Friday morning and will impact Jackson Hole through Saturday evening as the latest trends have slowed down this system a bit. The heaviest precipitation on Friday morning will occur in Yellowstone, before shifting south into Jackson Hole during the afternoon and evening. Yellowstone could pick up a few inches of snow on Friday morning above 7,500 ft.
Jackson Hole will see its heaviest precipitation from Friday night through Saturday morning, with additional rain/snow showers lingering into Saturday afternoon and early evening. The rain/snow line will rise to 7,500-8,500 ft. on Friday afternoon before falling to 6,000-6,500 ft. on Saturday morning. The town of Jackson could see some snow falling on Saturday morning with light accumulations possible in the GTNP valley and certainly in Yellowstone.
The higher elevations of the Tetons above 8,500 ft. will pick up 8-16 inches of snow from Friday morning through Saturday night. Total precipitation in the Tetons and Yellowstone over the next 3 days will range from 1-2 inches, while the Jackson Hole valley will see anywhere from 0.5-1.25 inches.
Sunday will be an in-between day with lingering cool temperatures and scattered clouds. Overall, conditions will start to dry out, but some isolated light showers can’t be ruled out either. On Monday, we will finally dry out with decreasing clouds and warmer temperatures.
