Was mentioning in another thread, while it may have had the right idea for all the wrong reasons, the GFS for the 6 days or so prior to the storm had the mix and sleet area consistently in S PA more than any other guidance. Actually sniffed that out and preformed better than the mesos in that regard....but again, more so a function of slp being more N but if we followed Miller B trends and used the GFS as guidance, it was consistent with the mixing looks yet we all shrugged the GFS off as a messy transfer, too far N etc when in actuality at least for Southern PA it didn't do bad. Took till the end to get the higher snow totals and QPF in the LV so it failed there.
