Daily snow observations from GHCN stations are available using the pulldown menus below to select the state, month, and year of interest for either snowfall or snow depth data. Average monthly snowfall at Togwotee Pass is very similar from November through April, and in fact, April is the snowiest month on average by a small margin. The * 83 months of September on record with no snowfall. The numbers are for the total amount of snow and for how many days it snows at least 0.1 inches (0.25 centimetres). Additionally, the Moran weather station (where average snowfall is 174 inches) receives heavier snowfall when storms move across the northern Tetons and northern Teton County, because there is a little gap just north of the Tetons where Grassy Lake Road is located, and moisture can stream through this gap unobstructed and result in heavier snow over northern sections of GTNP. Spring Frost/Freeze, Additional Information Heading north of Jackson Hole, snowfall increases significantly over the southern half of Yellowstone despite a more gradual rise in elevation compared to traveling east toward Togwotee Pass. Thus, there is no accurate snowfall measurement since the snow will usually drift deeply into the ground. http://www.firsttracksonline.com/snowmaking.htm, 51c. Based on this categorization, the most common form of precipitation in Laramie changes throughout the year. about 127% should be considered "true" SNOTEL Normals.
