We will see a transition from a cool pattern to a much milder pattern over the next several days with some light precipitation from Thursday through Saturday and drier conditions on Sunday and Monday.

Thursday – Thursday Night

A minor disturbance will arrive from the northwest with snow showers developing by late morning and continuing through the evening. Winds aloft out of the northwest will create a rain shadow effect over the JH Valley with lighter and more intermittent snow showers as a result – any accumulations in the valley will be brief/light.

The Tetons will pick up 1-4 inches of new snow from this disturbance. In the valley, precipitation should remain mostly snow but some rain could potentially mix in around town late in the afternoon and evening. High swill reach the upper 30s in the valley.

Breezy winds can be expected on Thursday out of the west/northwest in the mountains and south/southwest in the valley.

Friday – Saturday

Mostly cloudy skies will persist through the day on Friday with areas of fog and low visibility also possible. Milder air will also arrive with highs in the 40s in the valley and snow levels rising to 8,000-8,500 feet.

Isolated light showers will be possible on Friday and Friday night but will only amount to very light precipitation.

On Saturday, another minor disturbance will arrive from the northwest with more numerous showers expected in the morning giving way to fewer/more isolated showers in the afternoon and evening. Average snow levels during this event will be around 7,500-8,000 feet.

Sunday – Monday

Warmer and drier conditions will prevail both days with partly cloudy skies expected and highs reaching the 50s in the valley as high pressure strengthens over the area.

Extended Outlook

The next storm along with a cold front will arrive on Tuesday. Precipitation will likely start as rain in the valley but could change over to snow depending on the timing of precipitation with the cold air arriving behind the front.

This is unlikely to be a significant precipitation event, but the front will usher in much colder temperatures for the middle part of next week.
