How do I read it?

Summary: In the rows labeled "sky conditions", find a column of blue blocks. You can probably observe then.

Details: Read the image from left to right. Each column represents a different hour.
The colors of the blocks are the colors from CMC's forecast maps for that hour.
The two numbers at the top of a column is the time. A digit 1 on top of a 3 means 13:00 or 1pm. It's local time, in 24hr format. (Local time for Burlington is -5.0 hours from GMT.).
