Buckrail - Mountain range

JACKSON, Wyo. — Over the past week, we saw a transition to a warmer and drier pattern across Jackson Hole. The higher elevations of the Tetons saw up to two inches of snow last Monday and a trace of snow on Sunday night, and the Rendezvous Bowl Plot recorded 0.87” of rain and liquid-equivalent snow over the past week.

The town of Jackson picked up about a quarter of an inch of rain over the past week, while Teton Village received a half-inch, the heaviest of which fell on Thursday. Wednesday was the warmest day of the past week when the high temperature hit 70 at the Jackson Hole Airport and 69 at the Town of Jackson weather station.

As a result of the warmer temperatures, snowpack melted at nearly two inches per day across the higher elevations over the past week. Even so, current snow depths remain above average for early May. Across the valley, the snow depth at Togwotee Pass is slightly above average as well. The snow depth at the base of Jackson Hole Mountain Resort is now down to zero.


Weekly Weather Outlook — May 4-10

May is well-known for being one of Jackson Hole’s wetter and more unsettled months with dry spells typically lasting no more than a few days. That is not going to be the case this week! An unusually persistent dry pattern is taking hold with minimal rain chances expected for at least the next seven days.

Even our most recent storm system trended too far north and we only saw light precipitation amounts on Sunday and Sunday night as a result (this did include some light snow on early Monday morning as well).

We’re now on the back edge of this system and the rest of Monday is looking dry with skies becoming mostly sunny in the afternoon. Highs will reach the low 50s in the valley with light to moderate winds from the west/southwest.

Here is a look at Monday morning’s satellite and upper atmospheric weather chart, which shows moisture exiting the region to the northeast and a ridge of high pressure building in from the west.


Mostly sunny skies will continue on Tuesday with highs warming up into the low 60s in the valley. Wednesday will be the warmest day of the week ahead of a storm system that will pass north of our area on Wednesday night and Thursday.

Winds will pick up out of the southwest on Wednesday afternoon and a light shower can’t entirely be ruled out on Wednesday afternoon or evening, but most areas in Teton County should stay dry.

However, a cold front will arrive on Wednesday evening, ushering in cooler temperatures for Thursday. Temperatures will start to warm back up again on Friday and the stretch of dry weather will continue through the weekend.

Most nights will see temperatures falling below freezing this week, largely due to a lack of cloud cover. Our average high temperature in early May is in the low 60s, so we won’t be exceptionally warm this week despite the dry conditions.

Looking beyond seven days, long range models are advertising a shift to more unsettled weather by approximately the middle of next week, though confidence is low this far out.
