Vent not Sealed - Cold Air Coming In

Now that the days are getting colder here in the North East I noticed that my furnace vent is allowing cold air to enter the house. Is this normal conditions for this vent in the picture below.
If I hold my hands up to where the arrow is in the picture I could feel the cold air seeping in.
