Certainly things can go boom! I don't think the GFS/Euro will have a good handle on it until 1-2 days prior, or even the day of. Sometimes they can not detect some features well due to the lower res. There is still model inconsistency, even with the GEFS members. Of course, the high res mesoscale models will show better clarity since they are at a much higher res.
There is still a low, it's a surface low that is embedded within the boundary. The setup looks good at 500mb concerning no shear, however there is shear taking place in the mid layers, which isn't good. If the shearing takes place, this means the system would likely give away to flurries on the back side of the boundary.
