Looks like rain...

In the Sahara Desert. It appears as though the trade winds that once were constantly flowing from north Africa to the Caribbean are no longer functioning. There has been a consistent stream of air flow pushing from the central Pacific that has brought much of the weather seen in the southern states over the past 18 months that I have been noticing this phenomenon. The persistence of this flow has driven many weather systems from the central/southern American continents out into the Atlantic and are now crossing the ocean and affecting the western/northern African continent. From the looks of current satellite images, it looks like a significant rain is going to fall on the desert coming from the west. And it looks pretty creepy on the satellite map.

This is the link to the base map, you can turn off the confusion and watch just the satellite loop, very telling. It's a new site so I haven't learned all its workings yet.
