This graph shows expected Wind Speeds (in mph) & Direction over the next 5 days, at around the 10,000-ft. elevation in the mountains. The lower Light Green Line represents Average Wind Speeds for the day. The upper Dark Green Line represents the maximum wind gust speeds expected. Average overall Wind Direction is labelled with an abbreviation, such as: W= West, SW= Southwest, NNW= North-Northwest, etc. This indicate the direction from which the wind is coming.
Thunderstorm Graph Description
This graph shows the probability of Thunderstorms around the Jackson Hole area & the Teton Mountains.
This graph represents the likelihood of Thunderstorms & dangerous Lightning occurring in the area, for both DAY & NITE. The bar scale represents LOW, MEDIUM or HIGH probability of Thunderstorms. DAY generally covers the time period between 6:00 AM & 6:00 PM. NITE is between 6:00 PM and 6:00 AM the following morning.
Snow Precipitation Graph Description
This graph shows the average expected snowfall amounts for the next 5 days in inches, broken down by DAY & NITE to give an idea of when the snow will be falling. Gray bars are for valley snowfall, Blue bars are for mountain snowfall at around the 9,000-ft. elevation in the Tetons. Number plotted is for a quicker read on mountain snow amounts.
Note: Snowfall amounts can vary widely from one location to another. In general, the Town of Jackson will get less snow than locations along the base of the mountains (Wilson, Teton Village & Moose). As you go further north into Grand Teton National Park (Moran, Colter Bay & South Gate of Yellowstone), expect much more snow than what is forecasted here. Mountain snowfall will vary widely by elevation & location, depending on favored flow directions & wind redistribution.
