Below are links to a HYSPLIT 12-hour trajectory prediction based on the
last estimated lat/long that I saw on APRS.fi at 0300 UTC and Bob's
altitude estimate of 15,000 feet.  The first link is to a PDF and the
second is to a Google Earth KMZ.

This prediction puts the balloon over Bermuda at around 2100 UTC on 30 Mar
2012.
