JACKSON, Wyo. — Another big storm is on the way for the Teton Range late this week. The National Weather Service in Riverton has issued a Winter Storm Watch for all of Teton County from 11 a.m. Thursday through 5 a.m. Saturday.
Significant amounts of Pacific moisture arriving via westerly flow will result in a long-duration snow event with snow arriving on Thursday afternoon and continuing through Friday night.
Two-day snow totals through Saturday morning will range from 1-2 feet (12-24 inches) in the Tetons and 2-6 inches in the Jackson Hole Valley.
Winds will not be as strong during this storm compared to prior days, but gusts of 30+ mph will still occur across the higher elevations with the primary mountain-top wind direction being out of the west/southwest.
Skiers and riders can expect the deepest powder conditions on Friday, while Saturday morning will offer leftovers as well.
Travel conditions over Teton Pass will start to deteriorate on Thursday evening, while the most challenging conditions can be expected during the Friday morning and Friday evening commutes. Be sure to check WYDOT for possible closures due to avalanche control.
We will see a break in the action on Saturday morning, then another storm passing south of the area will result in a glancing blow for Jackson Hole with another round of light to moderate snow expected on Saturday afternoon and Saturday night.
With winds out of the south/southwest, there won’t be as much of a difference between snow totals in the valley versus the higher elevations compared to the Thursday-Friday storm.
For Teton Valley and Grand Targhee – Heavy snow is also expected on Thursday and Friday, but less snow is expected on Saturday compared to JHMR and the southern end of the Teton Range as south/southwest winds are less favorable for Targhee.
We should see a break in between storms on Sunday, then the next storm is expected to arrive on Monday-Tuesday as our active February pattern continues.
