Fog persists; chance for weekend snow
Patchy dense fog will continue into Friday morning. The active word here is "patchy" as the weather pattern is changing and the fog won't be as widespread and there will be more breaks in the low-lying moisture.
Dense Fog Advisories issued by the National Weather Service are set to expire at 5 a.m. Friday for Anchorage and the Mat-Su Valleys. There will still more fog forming Thursday evening and which will stick around into Friday, but it should lift a bit more, and by the afternoon, skies should be partly cloudy.
With temperatures in most areas getting down to the freezing mark, expect freezing fog at times which will make for slippery conditions on roadways, walks and other surfaces.
Further north in the interior and slope, there are many Winter Weather Advisories posted for snow Thursday evening into Friday. Driving along the Parks Highway will be snowy with up to 6 inches of new snow Friday with some ice hidden below.
The weather pattern continues to change this weekend and a front will slide down from the Northwest, and by Saturday afternoon, we will have increasing clouds that could start dropping rain that turns to snow in the evening. Overnight and on Sunday there could be anywhere from half-an-inch to an inch or so of snow accumulation in Anchorage with some other areas getting up to 2".
That front will also usher in colder air and temperatures will drop to more normal ranges (lows from the teens to mid-20s and highs around 30 degrees) by Sunday. Monday should clear out and be mostly sunny as a ridge quickly replaces the weekend disturbance.
Temperatures will drop further as the cold northerly flow continues and there will be a fair amount of sunshine next week.
