There's something here people are missing ...

so Lyons explains the due West movement in spite of all models screaming "north"by noting the low latitude and that it can be hard to turn a large storm north. Well, it didn't seem to be much trouble to turn Ivan from the W to WNW earlier today, and it's at higher latitude now.

Prediction is one thing- can't expect science to know the future. But science/meteorlogy SHOULD be able to point to something and tell us "this is why this storm just went west" and I haven't heard a convincing explanation yet.

There's some missing factor/reason why this went west- nothing happens in physics without a reason- what is it?

Maybe tonights G-IV jet mission will have some answers to that question.

Slight deviation in course or a jog, last frame or two seem to indicate the WNW resuming

Although Lyons may not have given a reason, I have heard several possible explanations on this board so far.

The storm is still very far south. At lower latitudes the coreolis effect has less impact on a storms path.

There is east to west flow across that area.

The storm is very large, and large storms can be less impacted by other steering patterns.

Those are all feasible reasons.

The atmosphere isn't a perfect pattern.
At different heights, the wind can blow at different speeds and directions. That can cause anomolies.
This may explain what happened this evening.
We'll have to watch a few more frames of
the loop tonight to see if the WNW did indeed resume.
