After a low pressure zone off the pacific got out of control and moved toward the Bay, 0.8" of rain poured down at the CCAG. The TMAD's humidity finally reached it's highest, 99%, which is rare for a desert. This means the air is holding 99% of it's water vapor capacity. Not quite water yet, but close! I experimented with some slo mo films of the rain, and a Timelapse capturing rain on Friday, November 19. As you can see, it is very humid before a storm. I was playing four square with my friends an hour before the storm, and the temperature rose to 70F. I was a little confused, but two hours later it started pouring. I found out that the humidy was because of the cold front. War air slowly moves close to the ground as cold air moves over. In the Timelapse below, you can see the dark gray clouds shifting in when it's hot. A general rule is that if you can't visually picture the clouds shape (if the clouds are so clumped together) then it should be humid. Check out the Timelapse below. When the clouds start moving to the Northeast, the rain falls in sheets.
