Over the next 24 hours, 4 inches of snow has been forecast for Fairbanks, prompting a winter weather advisory from the National Weather Service for the whole of the Middle Tanana Valley.

“Use caution this morning as ice remains below the new-fallen snow on many of the secondary roads,” a Weather Service forecast states.

The advisory, which notes that drivers should “plan on slippery road conditions,” is in effect until 10 a.m. Saturday and covers Fairbanks, Fort Wainwright, Eielson Air Force Base, Ester, North Pole, Moose Creek, Two Rivers, Fox, Chatanika, Chena Hot Springs, and Sourdough Camp.

Joe Kryston, a meteorologist with the Weather Service, said the snow is anticipated to be heaviest in areas south of Fairbanks but added that several inches of snow are expected to fall in Fairbanks and its immediate surroundings.

“It’s going to stay below 30,” he said of the temperature. “We picked up over an inch this morning, and we’re expecting another one or two inches to develop overnight. It’s going to be cold all weekend.”

As of 8:13 a.m Friday, a Weather Service forecast for the area states that snow will “continue through the morning commute in the Fairbanks area with a heavier band of snow currently moving through.”

Up to 2 inches of snow may fall through the morning.
