What the National Weather Service wrote

Alaska DOT reported blizzard conditions through Thompson Pass, with blowing snow reducing visibility to less than 1/4 mile.

The wider storm

An area of high pressure formed over the Central Interior, causing cold air to build up over the Copper River Basin. Meanwhile, a weak trough from a lingering low just south of Yakutat caused the pressure gradient to increase through the Chugach Mountains. This caused blizzard conditions along Thompson Pass.
