It’s been a pretty foggy morning across the Huntsville metro area! But if you’re looking for insight on the extent of the fog from early morning GOES visible imagery, good luck! Mid-level clouds were obscuring lower-level features for a large portion of the region.
Fortunately, the earlier VIIRS pass gave a much better perspective on the fog, despite being on the very edge of the early morning pass.
Some nice details stand out in this image, particularly the multiple river valleys that can be picked out across north Alabama and middle Tennessee. This implies that the fog may be a little more localized than previously thought, and agrees nicely with the rapid improvement of visibility that is being reported after sunrise.
