A new TIP and TLE have been released by Space-Track.org. The window is down to 12 hours, from May 8th at 4:52 PM EDT until May 9th at 4:52 AM EDT. There are still two passes in play that could produce a visible reentry for the local area. The passes are now a minute earlier than the previous 18-hour window. Also note the center of the 12-hour window is now over New Zealand and on the same track that passes over central Florida.
I should also mention there are other state and commercial entities that are releasing reentry predictions, specifically EU SST and The Aerospace Corporation. Their predictions have the same two passes in play.
