The top 7 most overused cloud metaphors, sorted by weather pattern

Along with innovation, agility, and efficiency cloud computing has brought us a bevy of clever metaphors around the cloud concept. Unfortunately these play-on-words headlines are quickly becoming cliches. Below is a list of the most common metaphors I've come across, and headlines that use them. I hope this list will force us all to be a bit more original. (Note: Sorted by weather event chronological order)
