First, Saturday night into Sunday morning, big chinook. It is very likely that it will get significantly above freezing throughout the area. Then, about as strong a cold front as ever is seen in Interior Alaska comes blasting through late Sunday afternoon or evening. Here's the forecast for the 850mb temperatures (about 4500' MSL, a decent guide to the temperature of the low level airmass).
Yes, that's plotted correctly: the model is forecasting an almost 9C fall between 3pm and 6pm Sunday. There will be snow and lots of southwest wind as the cold air returns. Above tree-line on the highways north of Fairbanks it's really going to howl. The southwest winds will break through in town too; I would not be surprised to see Fairbanks Airport report blowing snow at some point Sunday night/Monday morning.
