Take a look on the left side of the animation. See those three aligned blue spots, with the one blue spot to the lower right? Those are called orographic clouds, formed when moist air is lifted up over an obstacle; the air cools and the moisture condenses, forming clouds. What kind of obstacle on the Martian surface could do that?
Volcanoes. Yes, volcanoes: in the animation, you can actually see clouds that have formed as the Martian atmosphere moves up the banks of the enormous volcanoes on the Tharsis shield, a massive uplift feature on Mars. The fourth cloud to the lower right is actually marking the spot of Olympus Mons, the largest volcano in the solar system.

This means what to us here on earth (not being a smart ass, serious question)
Well, we already know Mars has water. It means there is potential to send a manned mission, and in the future setup a base for further exploration on that planet. Obviously that would be very hard to do, but the existence of water makes it far more do-able.

Those must be some huge volcanoes. I was hoping it wasn't a new Burger King, MacDonald's or a Starbucks.

The water on mars is either underground or frozen at the poles. The amount of water in the atmosphere is negligible, in fact almost non existent.

Obviously. That doesn't negate anything.. We know most of it is underground from using the satellite technology and scanning the planet, and when the rover scraped the ground and found water right under the surface.

Mars is what Earth is going to look like in a couple billion years.

Not really. Earth is large enough that it will hang on to most of its atmosphere, at least it will never get as thin as Mars'. Also Earth will never get that cold. Once the sun balloons into a red giant earth will get even hotter (all the water will evaporate).
