You have to look at what is in front of you FIRST, then you might want to take history into consideration - but you have to take into consideration the conditions that exist now!
Its like y'all are looking at a 30 year old road map of an area that has been extensively developed, saying "there can't be a road here! its never been that way!" Maybe it wasn't, but the road is there, you can see it and touch it, and you have to deal with it.
The ridge is there and there's no sign of anything slicing through it. Not to say that its impossible ... but we have to deal with the conditions we have. Climo won't break the ridge. If you see something that will, say so, but its silly to predict a landfall in the panhandle if the upper air conditions just plain won't let that happen.
BTW, here's hopin' Chris is cravin' a Corona in the most desolated desert he can find....
You are correct. That's how I forecast.
Take a look at the synoptics I see. If I see something that is very unusual...then I consult climo. If it has NEVER happened before...then I take a second look. They teach you in school to not forecast records...unless you are for absolute certain it will occur.
Consult climo to help produce a forecast...NOT make one. This has happened before. Given the SYNOPTIC pattern...it can happen again. Go back to 1932 and 1933...when a storm was in this location (cat 1 and a TS)...you will probably see the same synoptic setup. The pattern happens all the time...it's just there is not a storm right in that spot to be steered under it.
Fredrick was 1.5 degrees south of where Chris is now....as a 50kt tropical storm.
It went into the Gulf. Why? There was a big high north of it...and it stayed over the Ohio Valley until a longwave trof moved into the central part of the country and a large upper low in the western Gulf yanked him north.
There is no longwave moving in that we can see...at this time. What we do see is a big ridge.

Because the GFS weakens it to an open wave? right?

Essentially the Days 6 and 7 points are simply extrapolations of the track beyond day 5. The fact that's it an 'L' and not a hurricane or TS symbol is merely them stating, "Whatever form the TC is in, we think it's center will be near here on day 6 (7)."
