We had a break in the clouds earlier today and I was able to get a little footage of just how fast the puffy cumulus clouds (forming fairly low to the ground) were racing by.  You can also see some altocumulus coming into the frame from the right (and more from the south and southwest), indicating wind shear which will be supportive of strong to possibly severe storms later tonight.
