ANCHORAGE (KTUU) - While under partly cloudy skies Thursday in Anchorage we will see a high near 8 degrees.
A few snow showers will linger across the Copper River Basin through Thursday morning along with flurries elsewhere across Southcentral due to storm development in the northern Gulf. This low also helps to pull colder air down and across the southern Mainland bringing colder trends through the end of the week.
Gusty winds from the Interior will increase this morning across channeled terrain and along the western Gulf, including Kodiak Island due to the rush of cold air from north to south. As the low-pressure storm becomes stationary over the northern Gulf, we can expect gusty winds to persist over the next several days for Seward, Portage Valley, and Whittier. Airflow out of the north will also increase for Broad Pass and the Matanuska Valley due to atmospheric pressure differences developing on Thursday afternoon. Wind across Thompson Pass and the Copper River Delta slowly increases Thursday into Friday, with peak wind flow anticipated on Saturday. Winds for these locations are highly dependent on the location of the low-pressure system.
For the extended period, the big picture will be low pressure persisting over the Gulf of Alaska and south of the Aleutians with strong high pressure over the eastern Bering Sea and cold Russian, Arctic air moving over the mainland. For the mainland, this translates into below-average temperatures pretty much for the rest of the forecast period and maybe over the next two weeks. This cold air in place will result in airflow out of the north producing gap winds through the mountains, passes, and coastal locations.
Partly cloudy skies in Anchorage on Thursday with some early snow flurries and a high of 8 degrees. Mostly clear Thursday evening as we drop down to -4 degrees below zero.
Partly sunny skies in Anchorage on Friday with a high of just 2 degrees. Mostly cloudy skies Friday night with a low of -10 degrees below zero.
Looking ahead, Friday we will be under mostly cloudy skies with a high of just 0 degrees but we drop down to 12 below on Saturday night.
