Mild conditions over the next few days will give way to a cooler and more unsettled pattern starting Saturday night and continuing into next week.

Thursday – Friday

Widespread fog and low clouds are present in the Jackson Hole Valley again on Thursday morning with clear skies above 8,000 feet. The fog will eventually clear out around midday with mostly sunny to partly cloudy skies on Thursday afternoon. Afternoon temperatures will be quite pleasant for this time of year with highs in the upper 50s in the valley.

A cold front will move through on Thursday evening but most of the moisture and energy with this front has trended farther north. As a result, we will only see some isolated showers at best with the frontal passage, and snow levels will be in the 7,500-8,500 foot range behind the front.

Winds will become strong and gusty as the front approaches on Thursday evening, and this will likely be the most noticeable impact.

On Friday, we will clear out again with mostly sunny to partly cloudy skies and highs in the mid-50s.

Saturday – Monday

Clouds will increase on Friday night and Saturday and there is a slight chance of showers during the daytime hours on Saturday as the next disturbance approaches. Overall, mild conditions will prevail during the day on Saturday with highs in the mid-50s in the valley.

Snow levels will be 8,000 feet or higher with any daytime showers that occur on Saturday.

More widespread showers will arrive on Saturday night as a disturbance moves across Western Wyoming. This will most likely be an overnight event, but there is a chance we could see some showers linger through Sunday morning as well.

Snow levels will start out around 7,500-8,500 feet on Saturday evening but will fall overnight behind the passage of a cold front and could reach the valley floor by first thing Sunday morning.

Cooler temperatures will prevail on Sunday with highs in the 40s in the valley, but we will also see a drying trend through Sunday afternoon and into Sunday night.

Another disturbance will move across the Central Rockies on Monday, but confidence is low on whether or not it will track too far south for Jackson Hole to see any precipitation. For now, we should expect a chance of light snow showers with snow levels likely to be near the valley floor.

Extended Outlook

The pattern is looking fairly active from about Tuesday through Thursday (11/9 – 11/11) of next week with additional disturbances possible. We will likely see a combination of rain and snow on the valley floor, but perhaps we’ll see our first meaningful snow accumulations of the season in the valley at some point.
