Snow and cold with advisories in parts of Southcentral today
While under cloudy snowy skies Wednesday in Anchorage we will see a high near 29 degrees.
We are seeing early snowfall in Kodiak as well as over the Kenai Peninsula northward to Anchorage Tuesday morning.
The Copper River Basin will also see a better chance for snowfall and could see some areas close to advisory snow accumulation levels this morning. When the storm leaves the area on Thursday then we can expect colder conditions with diminished cloud cover while winds pick up from out of the north through the usual gaps and passes.
For the extended period forecast beginning Thursday afternoon, we are looking at storms over the Western Aleutians with associated storm energy moving into the eastern Bering Sea.
The mainland will be staying dry at this time as cold air out of the northwest dives back down into Southcentral. As the storms move out of the Bering they will head towards the Peninsula and Kodiak Island.
Snow will move into the Peninsula and parts of interior Bristol Bay, but this storm will not move too much further north as the high pressure and cold Arctic air mass will be in place. So much of the storm energy will be diverted into the Gulf of Alaska and fall apart as it moves east on Friday. This weather pattern movement means that most of Southern Alaska will remain drier and colder.
Although Southwest Alaska will be open to brief bouts of clouds and snow through the weekend as the Alaska Range will keep Southcentral much drier given the fast-moving airflow out of the west in the upper regions of the atmosphere.
The upper air flow strengthens sometime Sunday night, and this will likely bring in more stormy weather for the Southern Mainland, with inland snow as well as stormy seas. Then, it looks to get colder thereafter as another Arctic air mass moves down from out of the north northwest.
