The storm that made a loop last year was Jeanne, as has been mentioned countless times in the past 24 hours.

As for the forecast, on visible satellite you can see both a northerly component in Franklin, as well as a trough currently diving across the Carolinas and Georgia. If these meet, Franklin will be quickly swept off to sea. If Franklin doesn't make it far enough north, the ridge is likely to reassert itself, leading to the anticyclonic loop scenario.

(I'm only repeating this speculation, as it too has been discussed numerous times already in this thread)
