Strange High Pressure Weather 2023-01-29 (Fairbanks, AK, US)

For a few months, I've been studying meteorology on the introductory level. The current weather is confusing to me:

=> Alaska Surface Report

=> PAFA weather observations

=> Fairbanks, AK hourly forecast

From what I've read and observed, usually when a high-pressure bubble develops in the winter, then you get clear skies and colder temperatures. But the opposite is the case: we have overcast skies and warm weather, and snow. Also, humidity is quite high: late yesterday afternoon, about 4pm AKST, we had frost suddenly form on all our parked vehicles. And that appears to be the NOAA forecast continuing for the next few days: warm temps, cloudy skies, and steady snow.

I'm curious what is the name and explanation for the current situation.
