JACKSON, Wyo. – October 2025 has been wetter than average and warmer than average for Teton County, though the past few days have been much colder with significant mountain snowfall. The next 7 days will be milder and drier, with a more active pattern possible after November 5th.
Recent Weather Pattern
Last week, we experienced a stretch of mild and dry weather with highs reaching the 60s from Wednesday to Saturday.
However, the first significant winter storm of the season impacted the area on Sunday and Monday, and temperatures have been much colder since Sunday.
The Sunday-Monday storm produced snow totals of 6-13 inches in the Tetons above 8,000 feet, including 13 inches apiece at Grand Targhee and at Jackson Hole’s Rendezvous Bowl Plot.
Snow also fell in the valley with totals of 0.9 inches in Jackson, 1.5 inches in Driggs, and 3.5 inches in Alpine.
After the storm, we saw our coldest temperatures of the season with a high of 38º in Jackson on Monday afternoon and a low of 13º on Tuesday morning.
For perspective, the average high and low in Jackson are 54º and 25º on October 23, and 50º and 23º on October 29. Averages are quickly decreasing at this time of year.
Preliminary October 2025 Review
Although there are still 2 days left in the month, no more significant weather systems are expected before the end of the month, and we can already say for certain that this month will end up being wetter than average and warmer than average. Snowfall has also been right around average in the Tetons.
Temperatures this month have been 1.2º F above average in the town of Jackson when factoring in both highs and lows. The warmest temperature of the month was 75º on October 9, and the coldest temperature of the month was 13º on October 28.
Jackson also received 2.46 inches of precipitation, which is above the 15-year average of 1.70 inches. By comparison, last October, we only received 0.61 inches of precipitation in town.
Precipitation totals elsewhere in October include 3.12 inches in Driggs and 4.44 inches at the Raymer Plot at Jackson Hole Mountain Resort.
The town of Jackson received 1.5 inches of snowfall in October, which is below average but more than last year, when we only received a trace in October.
In the Tetons, snowfall ended up right around average for the month. Early in the month, warm temperatures resulted in more precipitation falling as rain than snow, but by mid-month, several light to moderate snow events occurred over the higher elevations.
The recent storm on Sunday-Monday produced the heaviest snowfall of the season so far in the Tetons.
For the month as a whole, the Rendezvous Bowl Plot at Jackson Hole Mountain Resort has received 32 inches of snow, which is very close to average. The long-term October average at this location is 30 inches.
Current settled snow depths (the height of the snow currently on the ground) range from 10-14 inches at 9,000 feet, with only a few inches at 7,000 to 8,000 feet. A reminder that the snow season is just getting started.
Upcoming Weather Pattern
The pattern over the next seven days is looking quiet across our area as a ridge of high pressure dominates the weather pattern.
Storm systems passing north of our area will result in occasional clouds and gusty winds, along with a slight chance of showers in the Sunday to Tuesday window. However, snow levels will likely be 9,000 feet or higher if any showers occur.
This speaks to the milder airmass that is also expected. While we aren’t going to see temperatures in the 60s like we did last week, from Friday through early next week, valley highs will reach the 50s each day.
The increase in cloud cover will also result in milder overnight temperatures (20s to 30s) compared to the past couple of mornings when we were in the low teens.
The 7-day snow forecast from the European Ensemble Model shows this pattern well with the dominant storm track staying to the north in Canada, where heavier snowfall is expected.
While the next 7 days look mild and fairly quiet, there are some signs in the longer-range models that a more active pattern could return after November 5th with increased chances for precipitation.
November 2025 Outlook
We are now getting to the time of year when it will really begin to feel like winter as average temperatures quickly decrease and snow becomes more common.
November is the fourth coldest month of the year on average in Jackson, with an average high of 40.9º and an average low of 19.2º.
We can still see a wide variation in temperatures, however, with mild snowless spells and cold snaps featuring subzero temperatures both possible at this time of year.
In the past 15 years, we have seen temperatures as warm as 65º (in 2020) and temperatures as cold as -20º (in 2014) in the town of Jackson.
The town of Jackson averages 1.57 inches of precipitation and 12.2 inches of snow in November. The snowiest winter in town during the past 15 years was in 2010 with 28.3 inches.
In the Tetons, average snowfall in November is 76 inches at Grand Targhee and 58 inches at Jackson Hole Mountain Resort’s Rendezvous Bowl Plot. Data is courtesy of the Bridger-Teton Avalanche Center and BestSnow.net. The snowiest November at the Rendezvous Bowl Plot was 92 inches back in 2010.
For November 2025, we are anticipating near to above average precipitation and near to above average temperatures based on recent long-range model projections.
We may be right on the edge of the dominant storm track at times, though, with a stronger signal of above-average precipitation just to our north.
While confidence is low overall, the outlook for early-season skiing looks somewhat more optimistic compared to the past two years, when we had slow starts to the snow season.
