Big Sky Daily Snow
By Bob Ambrose, Forecaster Posted 3 years ago January 20, 2021
Small Storm for Thursday into Friday
Summary
Clouds will be more prominent today as they stream in on an active NW flow. That NW flow aloft will transport in a narrow band of moisture Thursday afternoon through Friday morning that could bring storm totals of 3-6” to Big Sky through noon Friday. This weekend looks mostly dry with below average daytime temperatures. Chances of snow return to the forecast Monday through Tuesday.
Update
Today:
At 8:00AM it’s 9 degrees in the Village and 18 degrees at the top of Andesite Mountain (at 8800’). No new snow was reported in the last 24-hours. Skies are currently cloudy over both Lone and Andesite Mountains. Light west winds at the top of Andesite are currently blowing at 5mph with a recent gust to 11mph.
Today expect partly cloudy skies with sunny breaks along with seasonal temperatures across both mountains. Plan for a high temperature across the mid/upper mountain at 9000’ of 21 degrees by mid-afternoon. West/SW winds will be at 10-15mphwith ridge top gusts to 25mph.
Extended Forecast:
A few flurries Wednesday night will bring perhaps a skiff to an inch overnight. A storm system moves into the region around noon on Thursday bringing persistent light snow with 1-3” likely by evening. In the scale of storms, this is a very narrow system (geographic range) and at this time we can put a 60% chance of the confidence of this forecast. Another wave of moisture moves through Thursday night bringing better chances of another 2-4” into midday on Friday. The sun returns on Saturday and Sunday but with cold Canadian air that look to bring daytime highs to around 13-15 degrees at 8900’. Chances of snow return early Monday with continued unsettled conditions into Tuesday.
