When using this view....

.....to look at the various steering currents, which feature has, or will have, the strongest influence on Matthew's track?

Looks like the upper level low moving through western Kansas, across the Oklahoma panhandle
into the Texas panhandle MAY enhance the more easterly movement, as we go though time.

I would expect that to help enhance a more Northeasterly track unless it begins moving in a SE direction. The high is still there to the East and not retreating East. Unfortunately what I am seeing is a track that will take Matthew into the same areas Ivan went.

That makes sense, David. The way the ULL is moving southward is "a start" to a more SSE and/or SE movement. They do tend to swing down and make that left turn [N to S movement to NW to SE movement].
