Colder air has arrived and it feels a bit more like winter on Wednesday morning with morning lows in the upper single digits to low teens in the valley and around zero at the top of the tram.

Wednesday – Thursday

Mostly sunny skies and chilly temperatures will prevail on Wednesday with highs reaching the low 30s in the valley. Wednesday night will be the coldest night of the season so far with overnight lows falling to near zero in the valley.

Thursday will start out with mostly sunny skies before giving way to increasing high clouds in the afternoon with highs reaching the low 30s in the valley.

Thursday Night – Saturday

A storm approaching from the west will result in a long duration snow event for the Tetons from Thursday night through Saturday with snow falling at light to moderate rates, but adding up nicely over time.

Light snow will arrive on Thursday night before picking up more during the day on Friday and into Friday night.

The JH Valley will pick up light snow accumulations on Friday morning through about midday, with amounts ranging from 0.5-1.5 inches around town and south of town, while the West Bank and areas north of the airport could see slightly higher amounts.

As warmer air arrives, temperatures will rise into the upper 30s in the valley on Friday afternoon with snow mixing with or changing to rain. Snow levels could reach as high as 7,000 feet or so during the warmest part of the day on Friday.

Snow levels will eventually lower to the valley floor again on Friday night and Saturday, but any valley snowfall on the backside of this storm will be light.

The Tetons will see their heaviest snow on Friday and Friday night, with lighter snow showers continuing on the backside of the system on Saturday before tapering off by late afternoon or early evening Saturday.

Snow totals from Thursday night through Saturday afternoon will range from 6-13 inches in the Tetons.

The highest travel impacts over Teton Pass can be expected on Friday morning, Friday evening, and Saturday morning.

Extended Outlook

Clearing skies and dry conditions can be expected on Sunday and Monday with highs in the upper 30s to low 40s.

Overall, Thanksgiving Week is looking quiet with no major travel impacts expected at this time. It’s possible we could see a glancing blow from a weak storm on Tuesday (11/23), but this would only result in light snow if anything at all.
