What
Snow expected. Total snow accumulations between 5 and 10 inches and a glaze of ice. Winds gusting as high as 30 mph.
Impacts
Travel could be very difficult.
Additional details
The snow will come in two waves. Snow is more likely Saturday morning into Sunday morning with 3 to 6 inches expected. There will be a break with lighter snow Sunday afternoon and night. On Monday, snow is likely in the morning with 2 to 4 inches expected but rain becomes more likely in the afternoon as warmer temperatures intrude and this will limit snowfall totals. Any rain will act as freezing rain and accrete on surfaces below freezing. This could make for slick conditions early next week.
Precautionary actions
Slow down and use caution while traveling.

A band of moisture will move through the Interior Monday and Tuesday, bringing with it warmer air and periods of widespread rainfall which could approach upwards of an inch for some locations. Cooling conditions during the overnight hours, especially after the system departs, will lead to refreezing of snow-melt and rain on roadways, creating particularly slick and slippery conditions.

Issued for this forecast zone · National Weather Service Fairbanks AK
A series of fronts are expected to move across the Interior on Sunday and Monday. The initial front on Sunday will bring a band of snowfall across the area. With this first front, light snow accumulations are expected.
The next front moving across the Interior on Monday will be accompanied by warmer temperatures, which could bring the potential for a light rain/snow mix in the valleys and moderate snow amounts across higher elevations. This could lead to slick travel conditions, especially during the overnight hours Monday night into Tuesday when the temperatures could drop below freezing once again.
Accompanying the second front will be a period of gusty winds across the higher elevations. This could bring some blowing snow concerns Monday night/Tuesday morning, which could reduce visibility to one mile or less.

Reading from Sat 2 AM · NWS gauge page
What this week’s weather means for heating, cooling, pipes and fresh air.
Tonight’s low: 23°−5°
Overnight low near 23°F — not yet at drip-the-faucets cold, but worth watching if it's forecast to drop further.
About 80% less heating than a typical week.
Heating degree days, base 65°F
47, 17 and 5°F are the test points heat pumps are rated at. About 21 hours are near freezing and damp, when outdoor units defrost more often.
Dry air outside (dew point 19°F). Indoor air will run dry too — a humidifier keeping indoor relative humidity in the 30–50% range is more comfortable and cuts static shocks, without going so high it fogs cold windows.
No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
Today’s expected high is 6°3° warmer than typical.
On average 7°4° colder than normal (daily mean temperature).
