A series of minor disturbances will bring periods of light snow to Teton County over the next several days with mild temperatures on Wednesday giving way to much colder temperatures from Thursday through Saturday.

Wednesday – Wednesday Night:

Partly cloudy skies on Wednesday morning will give way to mostly cloudy skies and gusty southwest winds on Wednesday afternoon. Temperatures will be mild with highs in the low 40s in the valley.

A cold front will arrive early Wednesday evening (near or just before sunset), and a quick round of moderate to heavy snow showers will develop behind the front and continue through the evening before tapering off later in the night.

Snow totals overnight will range from 2-5 inches in the Tetons and a trace to an inch in the valley. Snow will initially have trouble accumulating in the valley due to warm temperatures at the onset.

Thursday – Saturday:

Colder and drier conditions with isolated flurries will prevail on Thursday with highs near 30 in the valley under a mix of sun and clouds. Snow showers will then pick up again later Thursday night and continue off-and-on through Friday and into the first half of the day on Saturday.

Temperatures will be colder on Friday with highs in the low to mid 20s in the valley before warming into the low 30s on Saturday.

Sunday – Monday:

A warming trend will occur during this period with highs reaching the upper 30s in the valley. A storm system will be passing just north and west of the area during this time as well. There is a chance we could pick up some snow during this time, but it really depends on the northward vs. southward extent of the storm track which is uncertain at this time.

Extended Outlook:

There is a chance we could see a stronger storm arrive from the northwest around next Tuesday-Wednesday. However, warm air is also expected to arrive from the south, which could result in rain in the valley while the higher elevations could potentially see heavy/wet snow.

There is still a lot of uncertainty with the storm track this far out, as a favorable southwest flow could deliver heavy precipitation, but it’s also possible the strongest part of the storm could miss us (like most storms have recently).
