Question-- High Pressure and the Westward Track

[southerngale]

My local met said that the high pressure over the central states that is preventing the storm from making a northern turn is forecasted to move to the west, thus keeping Erika on a more or less straight westward track. He said, however, that the high hasn't made that move yet and they would be keeping an eye on it overnight. Anyone here know when this high is forecasted to head west? And what would it mean track-wise if it didn't move? Or the move is delayed? This is all, of course, assuming he knows what he is talking about in the first place!!

The main high moved southward from eastern Michigan into western Pennsylvania in the last three hours (between 5:00 PM ET and 8:00 PM ET).

The high is most definitely moving west with the storm. The trof is digging down the east coast very fast now, and the high is retrograding westward toward Texas.

I agree, wxman. My comment is what I have observed the direction the high pressure moved in the last three hours.

Ya. The barometric pressure has been dropping steadily here on the Mississippi Gulf Coast since noon today, so it's moving out.
