Summary
After a dry day on Thursday, a weak system will slide across the region on Thursday night. Light totals are expected by Friday morning. The rest of Friday and Saturday will then be dry before the action picks up on Sunday. Moderate to periods of heavy snow will fall through Tuesday, with decent totals expected for Jackson Hole and Grand Targhee. The details then become fuzzy as we look into the rest of next week.
Details
Jackson Hole and Grand Targhee were able to squeeze out another inch on Wednesday, bringing their season totals to 319" and 308" respectively. Before I jump into the forecast, I quickly wanted to share where we are sitting in regards to our snowpack.
Jackson Hole is currently sitting at 91% of average and they are cruising along just below the average line. As for Grand Targhee, they are currently sitting at 88% of average but not terribly far below the average line. In general, our snowpack is doing okay but we will need a solid month of March to really crank us up to where we want to be!

Back to the forecast!
Thursday - Thursday Night: We return to partly sunny skies with continued warm temperatures on Thursday. Mid-mountain temperatures will rise into the 30s so dress light if you plan to take a few laps up on the hills. Clouds will then begin to increase by late Thursday afternoon as another weak system takes aim for the region. Snow levels will again be an issue so as the showers kick off on Thursday evening, expect a rain/snow mix below ~8,000 feet. Periods of light showers will continue through the evening hours and into Thursday night before we dry out sometime after midnight. In total, we are looking at 1-2 inches (at best!) for the upper elevations by Friday morning.
Friday - Saturday: Dry weather will then prevail on Friday and Saturday as we await the arrival of our next storm on Sunday. The first in a series of heavy doses of precipitation will slam into California on Saturday and begin to make their way further west.
Sunday - Early Next Week: We will then join in on the action come Sunday as strong southwesterly flow barrels into the Teton Range. The southwest flow will be accompanied by good amounts of moisture and storm energy to bring us moderate to periods of heavy snow through early next week. Snow levels will again likely be an issue at the onset of the storm but colder temperatures will stream into the region by late Sunday night or early Monday morning. In total, we are looking at 4-8+ inches through Tuesday but look for adjustments over the next few days.
Later Next Week & Beyond: The models then diverge slightly on the details for the middle of next week. We could continue to see periods of off-and-on snow showers through the entire week or we could dry out and await the arrival of our next storm over the following weekend. I'll have more details over the next few days so stay tuned...
Thanks for reading and look for my next update on Friday morning!
