An arctic low is quickly diving southward towards SW Alaska, carrying cold and dry air behind as it moves towards the Gulf. Temperatures will drop below zero tonight along the Lower Kuskokwim Valley and northern interior portions of Bristol Bay, as far south as Koliganek and Port Alsworth, with apparent temperatures ranging from -20 to -30 degrees. Temperatures will warm slightly during the day Monday before dropping further Monday night. Lows could range from -5 to -15, with apparent temperatures dropping as low as -35. Three of the main factors that will determine how low temperatures get will be winds/gusts, sky coverage, and the influence of the Bering ridge moving into the area. There is still low confidence in how each of these factors will influence the setup over SW Alaska. Please continue to follow the forecast for additional updates as this system progresses. $$
