Jackson Hole Daily Snow
By Alan Smith, Meteorologist Posted 3 years ago April 10, 2021
Warmer and windy on Saturday
Summary
Closing weekend will mostly be dry aside from a few snow flurries possible as a cold front arrives on Saturday night. Strong winds can be expected on Saturday afternoon ahead of the front, followed by cooler temps, sunny skies, and lighter winds behind the front on Sunday. Next week looks unsettled with periods of snow showers and below average temps.
Short Term Forecast
Saturday will be sunny with warmer temperatures as highs reach the upper 30s on the upper mountain. However, an approaching disturbance will result in strong winds – especially in the afternoon with gusts to 50 mph expected.
A cold front will arrive on Saturday night and it's possible we could see a few flurries but little if any accumulation is expected.
Temperatures will be cooler for closing day on Sunday behind the front with highs in the mid-20s on the upper mountain. However, sunny skies will return aside from a few lingering clouds in the morning and winds will be lighter, so overall it will be a nice day to finish the season.
Extended Forecast
Most of next week looks unsettled with colder than average temperatures. First, a weak disturbance will arrive on Monday with light snow showers possible, but minimal if any accumulations are expected at this point.
A cut-off low pressure system will then develop west of the Tetons starting on Tuesday/Wednesday before eventually meandering south into Colorado by late in the week. Cut-off lows are always tricky and any slight variations in movement will impact how much precipitation the Tetons could receive.
Colorado and areas east of the Continental Divide in Wyoming will receive the brunt of the impact from this system. However, it's also possible the Tetons could pick up respectable snow amounts during roughly the Tuesday night to Thursday timeframe depending on the exact track.
Snow levels will also be down to the valley floor for most of this period.
Next Friday through Monday (April 16th-19th), snow chances should decrease as the low moves into Colorado but the pattern still looks unsettled with occasional snow showers possible depending on wind directions and how much moisture makes it this far north.
Confidence for this period is low since we're still about a week out and models have struggled to get a handle on this pattern. We'll also have to watch for any secondary disturbances that could develop.
We may eventually dry out with warmer temperatures by around April 20th, but once again, confidence is low given how much medium/long-range models have struggled recently.
Thanks for reading and check back for my final daily forecast of the season on Sunday. I'll also be posting a season recap sometime next week.
