Overall its a power comparison between the 2 anticyclones. There has been a walking speed wobble to the ssw over the last 12 hours but it means nothing. There was a upper low that was over the mid-atlantic yesterday that moved into Penns.... it felt the trough now entering the SE U.S. and has moved off the coast. Ophelia is now SSW of it and has been meandering that way cause it lost its N push from it and also the ridge over Nate is sliding ENE. So Currently there is a weak ridge over west-central florida into the gulf. Ophelia is on its eastern side with midlevel flow out of the NNE around the weak ridge. Now as the trough digs off the east coast tonight and into Friday, Ophelia will lose the ridge as it disipates and feel the trough. This should push her ENE Friday. Into the weekend expect most of the energy with this trough to move out to the NE leaving Ophelia behind near 75-76W and 29-30N, expect her Sunday to turn back to the ssw then w into Monday. She could be a Cat 3 by then but I dont expect anymore strengthning due to NE shear and wake waters that she caused over the last few days. Movement towards the Florida coastline with possible landfalls could take place Tuesday or Weds. Too far ahead for any projection, but from Jupiter-Charleston SC should keep tracking this...................................................
