The Google Search Console is missing a full day of data from the Search Analytics report.
First reported to me by @furnishHQ, if you look at your Search Analytics report in the Google Search Console, you will see that July 28th is just missing. It was skipped over.
I created an animated GIF to show you how when you scroll through the data, the 28th is missing.
It is not uncommon for Google's reports in the Search Console not to work 100% correctly. I assume this will be fixed soon and it is just a reporting glitch.

Update: Gary Illyes from Google said on Google+, "Thanks! We're aware of the delay and working on it."
