Damien thanks! We are neighbors I see...Glad you watch this board... it is very up to the minute far ahead of what one can get publically and accurate too.
HankFrank speculated that subsidence may be the culprit in the current 'respirator condition' of TD9, and if you look north to about 26N you may see the cause...it looks like a ULL with associated convective activity around its core and some low level moisture to work with...this looks awfully much like the presentation of Harvey last weekend to me, except the convection is not persisting. It seems to be moving back to the SSW a bit.
From the WV on TD9 however it appears the moisture from the south and east is entraining a bit into where the llc is and some consolidation of the low level clouds has occurred. It is moving just north of west from about 17.5 north.
It will need about 24 hours of consistent improvement to make it in my opinion, but some signs of life remain...
