BILLINGS — It is a new cold front that starting to push its way into the Billings area this afternoon causing all the fog. We started off Friday with light rain and snowfall in the area which then elevated the humidity in the city.

Once cold air moves in with the cold front that causes the humidity to the go all the way up to 100%, creating the fog.

At 3 p.m. the temperature in Billings is 33° with the humidity of 96%, which explains the fog.

Around the rest the state you can see how cold it is up along the high line. Temps there are only into the teens and as the cooler air settles down in southern Montana, where we've already got the moist air in place, it causes advection fog.

We call this advection fog, because the cooler air is affecting into the area causing the humidity to go skyward.

In a meantime, we still have a Winter Storm Warning for the Beartooth Mountains. There we could see another 5 to 8 inches of snow with wind still gusting to 45 mph.

To the North and East of Billings, we have Winter Weather Advisories for another 2 to 4 inches of snow in those areas.

The Doppler radar shows you the snow continues to overrun the cold air that's dropping down from Canada and kicking off the snow showers.

The high-resolution forecast model shows that little baroclinic band of snow continue to push its way into the Eastern edge of Montana.

However, Billings might see another batch of snow move in about 830 a.m. on Saturday morning.

After that we might see a few scattered snow flurries on Sunday morning, but clearing skies by Sunday afternoon.

Our temperatures will continue to roll back down from the 30s into the 20s overnight and then bounce back up to 31 degrees on Saturday.

We will keep it in the 30s through Tuesday and then jump up into the 40s on Wednesday and Thursday.
