Coldest nights in nearly a year heading to Southcentral
For the first time since the first week of December, temperatures were seasonal for Southcentral. Afternoon highs topped out in the mid-20s for Anchorage with varying temperatures elsewhere across the region. Colder air has been filtering in from the heart of the state and will continue to do so in the days to come, leading to some of the coldest temperatures we've seen in nearly a year.
With the presence of high pressure to our northeast having a strong influence on our weather, not only will we stay on the cold side but snow will be hard to come by. Cold air that is bottled up in the Alaska Range will spill into Southcentral overnight into Friday. This will lead to briefly rising temperatures into the afternoon hours Friday, before temperatures begin to plummet into the evening hours. Add in the clear skies and calm winds, many of us will have the perfect recipe for radiational cooling to take place. Areas with more snow on the ground will see the coldest temperatures, with other locations still cooling off into the single digits, but being a few degrees warmer.
Our coldest morning looks to arrive Saturday night into Sunday, when many of us will fall below zero for lows. This trend of cold air is only reinforced with a system moving in from the west. Unfortunately this looks to bring us only passing clouds, as high pressure eats away at any snow chances.
Heading into Christmas week we do warm up slightly, but still below average. Afternoon highs will be in the lower 20s, with overnight lows dipping down into the 10s.
Have a great end to the workweek!
