Subzero wind chills expected in Southeast this weekend
A change in the weather pattern will bring subzero wind chills to Southeast Alaska this weekend. The cold air moves in Friday night, dropping temperatures below average for this time of year. By the weekend, strong winds will bring a brutal chill to much of the region.
Much of Southeast will experience the warmest temperatures of the next three days early Friday morning.
By the afternoon wind will pick up and start advecting cold air from areas inland and to the north. Winds out of the north and north east will drop temperatures from the 20s in the morning to the teens by late-afternoon. Strong winds will also drop wind chills to below zero by the afternoon for most of Southeast. The strong winds will actually be the saving grace overnight.
Gusts will continue to top 60 mph in many areas, with sustained winds above 30 mph stirring the air down near the ground, keeping it from rising up into the atmosphere and cooling further. Because of this, the temperatures will remain in the single digits above zero overnight instead of dropping below zero.
However, the wind will keep it feeling much colder than it actually will be. In fact, it will feel like it is below zero in many areas, almost the same as the air temperature would drop to without the wind.
Saturday will be the coldest day of the next few. Temperatures will struggle to climb into the teens across the region. Then once again drop to the single digits overnight as the winds start to die down.
Sunday will start the warming trend, still frigid, the temperatures will be slightly warmer than Saturday.
By Monday the next storm system starts moving in from the west. This will bring warmer temperatures and the chance of snow to much of the region. Temps will hover in the 20s for Juneau through the start of next week.
