Jackson Hole Weather Thursday February 18, 2021

Mostly cloudy skies will prevail on Thursday with occasional flurries, but overall conditions should stay relatively dry through the daytime hours. Highs will reach the upper 20s in the valley but will only be in the single digits above 9,000 feet.

The next storm will arrive late on Thursday night and will come with two main waves. The first period of heavier snow will occur on Friday morning, before snow becomes lighter and more intermittent on Friday afternoon.

Snow will then pick up in intensity again on Friday night and Saturday morning as the second stronger wave arrives. Snow showers will continue on Saturday afternoon and evening as well before tapering off later Saturday night.

Storm total snowfall from Thursday night through Sunday morning will range from 14-29 inches in the Tetons and 3-9 inches in the Jackson Hole Valley. For skiers, Saturday will offer the deepest powder conditions.

Travel conditions over Teton Pass will be most challenging on Friday morning and Saturday morning, while late Friday afternoon/early Friday evening won’t be as bad due to relative lulls in the storm expected.

After this storm, conditions will only dry out somewhat on Sunday and Monday but additional snow showers will be possible. Cold temperatures on Sunday will give way to a more noticeable warm-up on Monday along with an increase in winds. The next storm is then expected to arrive on Monday night and Tuesday.
