Was about go Jaws and then the next few frames it just gets shredded.

I am not sure if the upper air pattern at that time frame really supports that outcome.  It definitely does not look like the last couple of weeks where we had a raging 50-50 low, eating away at storms as they approach our region. To my untrained eye the jet stream looks more sw to ne in its configuration over our region, which I would think would support a coastal low.  Then again I am not the expert on these 500 MB Maps..

I’d rather take no snow than what the Euro shows now verbatim.

There are some differences in the advertised longwave pattern between the globals. Euro digs the trough more than the GFS and delays the eastward progress of the thermal boundary a bit. Shortwave energy and associated surface low track is further NW.

Lol, the models still can’t agree on the potential Sunday night into Monday possibility, but some of you guys are depressed about what might happen after the undecided prior period?

On to 12z…

You are right, but the kind of agreement between operational models and ensembles is not typical and is normally only seen in slam dunks. For example, 2/6/10 and 1/16 were seen around a week out and held strong until game time with little waffling.

Looks like EuroAI I just worked up my nerve to look at (lol) actually looks to bring a northern stream lobe down and pulls up some precip from the system next week. That's a new twist. Interestingly, the southern storm is rain and not snow. Hmmm

Unlike the last storm, there is nothing to prevent it from trending NW as psu alluded to the other day.

hardly any blocking over greenland, s/w energy hanging back west. That PV is pressing south, but one tiny shift the other way, the track is coming north.

And you want a proverbial reshuffle? Careful now… you might get a SE ridge with that.
