Heavy fog is hanging on into the daylight hours in the Metro area, slowing the morning commute for many.
Along Wisconsin Avenue in northwest D.C. this morning, you can see about a block ahead of you. And that's it. It's forcing cars to go considerably slower than normal at this time of hour.
At the region's three airports, things are running smoothly, though minor delays of 15 minutes or less are being reported in some cases. The dense fog warning from the National Weather Service will remain in effect for the region for another hour. The sun is expected to break through at that point to clear things up.
