I’d imagine the March 93 storm showed itself early, and with now ancient models.

As I recall at the time, the global medium range model (LFM, limited fine mesh!!) of that day had it about a week in advance.  And it was being widely discussed 5-7 days out in terms of its potential and severity.  It was heralded as a numerical model success, for good reason.  That system was similar to other "big dogs" like Feb. 2010 or Jan. 2016 (I assume Jan. 1996 too?), where the synoptic setup was just so blatantly clear, and models tend to grab onto those early and not waver much at all.

Huh?  OK, seriously...WTF is going on there?  I have to assume there's some kind of shortwave around the Lakes area screwing up the flow or something like that.  Or simply no antecedent cold air in place at all.

Exactly right. A northern stream shortwave/low draws mild air on return flow. Thing is... models can't get the NS right 3-5 days in advance. Last thing I'm worried about on fantasy op panels is a NS shortwave. It may end up happening but no f'n way the gfs just "figured it out"

It actually trended better. But still too much ridging in front and not enough behind so the mid level trough goes neutral too far west and floods us with mild air on the southerly flow ahead of it. Strengthen the ridge to the west and weaken the ridge to the east and it’s suddenly a big snow. Like I said yesterday it’s a cows fart in the right direction from a snowstorm. But gotta laugh at that. That would be painful.

Yup...well, that just figures!  But you're correct, it's not worth worrying about how the GFS is handling a NS shortwave that far out...if there even is a NS wave by then in that precise location.

Butterfly wings flapping is a prettier image, but cow's fart works too!! :lol:

Alrighty, back to Calculus... See weather? I’m behaving!

Also, Question: What is the different on TT between “MSLP and Precip” and “Radar (Rain/Frozen)? The Radar one shows snow in places where there would be rain on the MSLP map. The Precip Radar map also looks a tad different... maybe smoother? Or less abundant?

Radar is an instantaneous snapshot of precipitation. The MSLP panel includes 6 hours of precip

I have to admit that I am very discouraged.  I know that it is too premature to give up hope completely (not yet Reaper), but I cannot escape the feeling that this upcoming respite is really just a relaxation of the crappy pattern, the mirror image of a January thaw.
