Conditions are still not exactly what i would consider as favorable for COLIN and this is probably the reason why he is not able to get a defined surface circulation going.
Granted this is all based off of 3 Z information but it is the information that we have until 6 Z would become available but that would not be till close to 8Z.
Upper Level low is essentially moving in Tandem with what is the remnants of COLIN. This ULL is providing shear but because the remnants are on the east side its also helping to fire off convection. However...the system is under between 10 to as much as 30 + knots of shear..
So this shear is helping to actually cause the northern part of the system to be sheered off and the convection on the northern end keeps warming and fading out. It also continues to fight against dry air on its western side as well as its eastern side.
This is the shear tendency map and you can see what is either to the north or NW of the remnants of COLIN. Essentially increasing shear. So the environment is not going to get any better with the direction that his leftovers are heading.
Then also the size of this system being broad is also another factor that is going to slow down any potential development.
The other factor that I think may also come into play here is with the MJO
While the MJO is still in the center ...the MJO as of the 3rd actually took a right hand turn instead of a left and appears to be heading over towards phase 5 potentially.
Basically until the ULL gets out of the way and the shear subsides any development should be slow to occur.
