Jackson Hole Mountain Resort will remain closed until at least Monday, February 13th due to a significant number of downed power poles along Highway 390.

Grand Targhee is reporting 4 inches on Thursday and this is only the beginning of a very active and wet period over the next 24-36 hours. 

Very warm and moisture-laden southwesterly flow will bring periods of very heavy snow and copious amounts of precipitation to the region through Thursday night and into Friday. It will likely remain all snow above 8,000 feet but rain will be encountered across the lower elevations and valley floors. 

Like a majority of the storms this season, southwesterly flow will favor Jackson Hole over Grand Targhee for the best accumulations. But since JHMR is closed, our full attention will remain on GT. Look for 8-16 inches of heavy, dense snow through Friday evening before colder air finally begins to enter the region on Friday night. 

According to the latest forecast from the Bridger-Teton Avalanche Center, "very dangerous avalanche conditions exist and all avalanche terrain should be avoided."

As the colder air arrives on Friday night and into Saturday, our main flow of weather will slowly transition from out of the southwest to eventually out the northwest by Saturday evening. This will bring us another round of light snow on Saturday, with 2-4 inches possible by Sunday morning. 

Our skies will then finally begin to clear out as we head into Sunday. Sunny skies, mild temperatures, and valley inversions will be the forecast through the middle of next week.

Our full attention in the extended forecast remains on February 17th and beyond as the ensemble forecasts introduce another active pattern for the West. 

We'll get a better idea on the exact storm track by early next week but all signs are pointing toward an active period through next weekend and possibly for the rest of February. 

Thanks for reading and stay safe out there!
