That seems extremely unlikely. There's nothing to move the Bermuda high out of the picture and hurricanes don't crash into high pressure ridges. They try to skirt around them.
The western edge of that ridge is what Frances is riding now. The ridge could weaken somewhat during the next couple of days allowing for a more northerly landfall than the current projection, but it's not going to go away.
If you don't have your stuff together now, there isn't much time left to do so.
We understand that....we're praying something changes. If enough people pray mountains can be moved!!! This monster is one massive mountain. Florida is going to be wiped out!!! God help Florida!!!

Reading the forecast discussions in the Midwest/Plains indicate the ridge will begin to move on Saturday. St. Louis office mentions winds turning SEly starting Friday. This would indicate the eastern ridge will be moving/weakening on its western end. Frances will follow the path of least resistance.
