Special Weather Statement
Issued: 12:34 AM Dec. 23, 2025 – National Weather Service
...LONG DURATION SNOW EVENT POSSIBLE THIS WEEKEND... A pattern change this weekend will bring the high probability of another long duration snow event that would give the northern half of southeast Alaska significant snowfall over several days. A quick-moving low pressure system will track through the eastern gulf Wednesday night through Thursday, bringing light snow to the central and southern areas. Then, a forecasted plume of moisture will move into the area beginning late Friday, with active weather lasting into next week. With cold air in place, and no significant warm up expected between now and this weekend, this plume of moisture would result in significant snowfall that would last through the weekend. Areas of uncertainty include how much moisture will be available for the snow - greater moisture amounts would result in greater total snowfall. Also, a surge of warm air from the south could allow for snow to mix with or possibly change over to rain later in the weekend, or transition the character of the snow from a dry snow to a heavy and wet snow, both of which would change final snow totals as well as snowfall rates. Stay tuned into the forecast over the coming days as we fine tune the forecast details.
