...LONG DURATION SNOW AND RAIN EVENT POSSIBLE THIS WEEKEND... A pattern change this weekend will bring the high probability of a significant winter storm to the southern half of southeast Alaska 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, moderate to heavy snow could start as early as Friday evening. This surge of moisture will be accompanied with warmer air, so the snow will most likely transition to rain beginning in far southern southeast Alaska as early as Saturday morning. This warmer air will push northward over the weekend, transitioning more areas to rain, potentially heavy rain. High uncertainty remains how far and how fast this warm air will surge northward. Stay tuned into the forecast over the coming days as we fine tune the forecast details.
