Still think confluence could play a role in this as originally discussed. CMC/ICON/Euro say what confluence, GFS/Ukie/GEFS say we think there will be some confluence. We all shall see in the next day or two (or three).

Know I'm preaching to the choir, butright now we just have a cone of possibilities including, but not limited to, track, strength, and qpf field. The models will continue to bounce around a bunch as these cones shrink in size....some will even stick to their guns until the end only to be completely wrong. Just follow the general guidance, in particular ensembles, for a "highest probability scenario." For now, we have a chance of a decent snowstorm somewhere...but that's all it is, a chance for some folks somewhere in the region.

Better sampling of the vort that drops in to create our cut-off (s/w) lands in BC in the next 12 hours. So maybe some model stabilization coming, but seems like downstream players are going to have just as much effect on outcome as upstream.

'Law of nature' for the models changes, nature itself is perfect and does exactly what it wants, we just try to guess using our best mathematics and knowledge to come to the same conclusion.

Getting into range where 6 hour fixes are satisfied.  Northern piece jumps ahead with this one. Trajectory of the second northern piece looks flatter. Leaving it to the southern piece. Ridging up front is similar to 0z, flatter than 6z.  Location of UL is similar to 0z.

You are correct it is  nature who decides what happens.  A model has never made it snow , rain ,or be sunny.

Lots of mess behind this as well which I'm thinking could lead to some late-game uncertainty because the energy to the west will affect the ULL blocking overtop and won't be sampled well for a while.

Those of you who hug the Euro will like this run. The answer will probably with the NAM.  Just kidding….

Going to be interesting when the short range models get into the mix. LOL

As the system progresses and potentially redevelops as a coastal
storm Monday into Tuesday in a period with uncertain stream
phasing, heavy rainfall potential should lift northward into parts
of the Mid-Atlantic and Northeast. Increasing progression should
limit runoff risks over much of this broad region. There is
however an increasing potential for the spread of wrap-back
accumulating snows and windy conditions across the marginally cool
Appalachians/interior Northeast Monday and Tuesday before the
whole system works increasingly offshore as a continued maritime
hazard. Behind this system, conditions across much of the CONUS
should dry out mid next week besides periodic intrusions from the
Pacific to bring some modest precipitation to parts of the
Northwest.
