RAPID CITY, S.D. (KEVN) - A Dense Fog Advisory is in place until 8 a.m. Friday morning, unless canceled early, for Butte, northern Lawrence, southern Meade, Pennington & Custer County plains. Dense fog will reduce visibility to a 1/4 mile at times. Icy conditions are likely in areas due to surface temperatures being below freezing. Even if the air temperature is a little above freezing, slippery spots will still be possible.

Foggy conditions taper off during the morning and some sunshine will be possible through the middle of the day before clouds return during the afternoon. Snow will move in during the evening hours Friday. Some light freezing drizzle could mix in with some of that snow initially, but it will fall as all snow by Saturday morning and through the day. Winter weather alerts will likely be issued by Friday morning for those expected to pick up more than a few inches of snow.

As of now, it looks like 2″-4″ of snow will be possible in Rapid City. The southern hills and southern plains will likely pick up 3″-6″ of snow. Spearfish, Sturgis and parts of northeast Wyoming will get around 1″-3″ with Sheridan getting 2″-4″ of snow. The closer you get to the North Dakota state line, the less snow you’ll get. Snow will likely create slippery roads. Winds will gust to 40 mph on Saturday, which will reduce visibility and make it difficult for crews out treating roadways due to the blowing snow.

A few snow showers could linger Sunday, especially for the southern hills and southern plains, but minimal additional accumulation is expected. Temperatures gradually return to near normal on Tuesday, but snow showers return Wednesday and temperatures drop back into the 20s to end the week.
