I think this very much has something to do with the no trade fee weekend at mtgox.

Does anyone have any news articles related to a possible cause?

Also, this is less than 3 day's worth of value so far, so it might be market fluctuation.

No article link on me, but my guess the cause is that there, with bitcoin having doubled a few times in a few weeks to new highs, are more people who feel it's overbought and want to cash out / lock in enormous gains that could briskly vanish / sell short than there are people who feel the opposite. Basically.

Here's a good place to watch the action: http://bitcoin.clarkmoody.com/
