High pressure over the region will result in a beautiful day for Jackson Hole with highs warming up into the low 60s under mostly sunny skies. Winds will become breezy at times this afternoon out of the west/southwest.
On Wednesday, highs will warm up into the mid 60s, but ahead of an approaching cold front, winds will become very strong in the afternoon out of the southwest with gusts to 40 mph possible in the valley. The cold front will arrive late in the afternoon, and we could see a few showers develop in the afternoon and nighttime hours but most of the moisture will stay farther north in Montana.
Temperatures will fall quickly behind the front, so any shower activity could result in snow accumulations of a dusting to an inch in the mountains, while a few snowflakes also can’t be ruled out in the valley overnight. Thursday will be a chilly day behind the cold front with skies becoming mostly sunny, while winds will pick up once again out of the west as the day wears on.
On Friday, a weak disturbance will pass just north and east of Jackson Hole, so a few light showers can’t be ruled out during the day, but for the most part, conditions should stay dry. Temperatures will start to warm up more this weekend as high pressure strengthens over the Rockies.
