IMO, there's alot more that needs to happen than just trending west but I am also not necessarily sold on some of the recent trends we have seen with the ridging and better interaction of the two energies...we've seen this happen plenty of times of late where within this time range (3-5 days) there are these subtle shifts which trend better. I suspect by 12z Friday we will begin to see a trend back in the opposite direction with the heights in the west and energy interaction.
Also, even with the better interaction of energies, the upper level dynamics still aren't very favorable for low pressure development at the sfc...we have to look closer to where the baroclinic zone is present to get some llvl spinup present and I think its just too far south to do any good for us. But that said, at least snow showers are still possible farther east.
