Jackson Hole weather from November 15 to 21, 2022


JACKSON, Wyo.– Winter came early this year with heavy snowfall in early November, followed by unusually cold temperatures in mid-November. High pressure along the west coast is causing a prolonged dry spell that will last through the remainder of this week, but temperatures will continue to be colder than average at all elevations.

Recent weather summary

After four months of consistently above average heat from July to October, November has been a bit of a shock so far with near mid-winter conditions in the first two weeks of the month. So far this month, temperatures are 5.2 degrees below average in the city of Jackson.

The first 10 days of the month saw an active storm track with frequent snowfall. So far this month, the Rendezvous Bowl Plot at Jackson Hole Mountain Resort (elevation 9,580 feet) has received 47 inches of snow.

The average snowfall here for November as a whole is 58 inches, so we’re on pace for a month of above average snowfall despite the current dry spell.

The Jackson Hole valley also got a lot of snowfall early in the season, mostly due to a big storm last week that dumped 9.6 inches of snowfall in the city of Jackson over a 48-hour period. Southerly winds during this storm negated the rain shadow effect of the Teton Range, allowing heavy snowfall to accumulate in the lower valley.

So far this month, the city of Jackson has received 12.6 inches of snow, which is already above November’s historic average of 11.5 inches, even though we’re only halfway through. month.

Beginning November 11, a cold, dry pattern began in western Wyoming due to a blocking ridge of high pressure that moved along the west coast. However, a steady flow from the north over Intermountain West strengthened the cold air mass over Jackson Hole.

From November 11-14, high temperatures in the Jackson Hole Valley were only in the teens to 20s and low temperatures fell below freezing for the first time this year on the mornings of November 13-14.

Forecast from Tuesday (15/11) to Monday (21/11)

A prolonged period of dry weather and below average temperatures will continue for the remainder of this week and into early next week.

The only chance of snow will be Thursday as a disturbance passes east of the area, but we will only see showers from this system at best.

Areas along and east of the Continental Divide (including Togwotee Pass) in northern Wyoming will see light accumulations of snow, however, with moderate to heavy accumulations possible in the Big Horn Range and the Beartooth Range, so be careful if you’re traveling to that part of the state.

Otherwise, it will be a fairly calm week with cold temperatures being the big story. A reinforcement blow of cold air will arrive from the north on Thursday. This will be more noticeable down the valley in the days ahead with strengthening reversals expected.

Despite the dry pattern, ski resorts are in great shape to open over the next few days and weeks thanks to early November snowfall and recent cold temperatures, the latter of which have resulted in good snow conditions.

Extended Outlook

The high pressure is expected to collapse next week in the days leading up to Thanksgiving, which should open the door for storms returning to the area before Thanksgiving weekend. The cold snap is also expected to ease around the middle of next week as milder air from the Pacific Ocean arrives.
