Fog or Cloud?

 We have been in an inversion almost all day where the clouds have been low at this elevation. The temperature has been in the mid teens and it is a poor day to drive anywhere. The cloud/fog blends in with the snow and it is hard to see where the road is and to stay out of the ditch.
The weather forecaster has said we will get 3-6" of new snow but I have filled the bird feeder three times today when normally I only have to fill it once. The birds have been going non-stop all day eating the suet and sunflower seeds. If I have to believe the weather people or the birds regarding the coming storm I think I put more trust in the birds. They always seem to know when a big storm is coming and today they have really tanked up.

 Above photo of the fog/cloud is so thick we can't see the end of the driveway. Below photo shows the visibility through the trees is better but still very limited. Not a good day to be driving about as visibility is so poor if you get stuck with the 99% humidity and snow if you get stuck you could freeze to death or in the least be very miserable. Best to just stay put and make sure there is enough firewood for the stove. The humidity also creates black ice and makes even dirt roads slippery.
