Predictably, the mid-week storm is turning into another southern slider and missing PA.  That's the seasonal norm.

It was all too delicate and tenuous of a setup.  Too many things to go wrong.  It's a shame all the models at once locked onto a big solution because it's a massive tease, but I think that's the danger of model watching outside of a couple days lead.

Also further demonstrates the tendencies of a cold-ENSO winter, and why the events in warm-ENSO winters are much more "stable" and easier to track.  This isn't even 1996 anymore, and the increased speed of the northern jet is difficult to navigate.

Anytime you are depending on the PV let alone interactions with individual lobes rotating around its absolutely tenuous. To be honest aside from maybe a run of the cmc this was never going to be a huge storm for us anyways.

For midweek - NAM looks like it wants more of a longer duration, steady, WAA type snow. Maybe a more modest…but more realistic “good” solution. 

Right now its really the only model showing it, but its an easier path (All Southern Stream) to something vs what we needed with the big phase. If it can amplify nothing to really suppress it.

The seasonal trend has been for a fast Pacific flow and for bigger storms to get shunted south and east whenever the TPV is involved. There's just no way to slow down the energy crashing into the Pacific North West which is knocking down the ridge. I still think we atleast get a storm bigger than 3 inches this season but it won't be this next one.

I agree, only to add that has been a problem to some extent (fast Pac flow) for more than just this season.

Eventful day with flooding, 50 MPH wind gusts, mini-paste bomb and now snow squalls.

NWS total will make a run at 3” (thought I saw 2.6” so far)

Will probably wind up over 5” since yesterday. Great winter scenes this weekend - just crappy the first batch got washed away. 

It was a great little event, I agree to bad the first batch got washed out, but better to have snowed and melted than to have never snowed at all. :lol:

Made the best of yesterday with an impromptu sled and snowman session with the boy. Daughter just got her permit so took her driving tonight to get some bad weather driving experience (some donuts in an empty parking lot too :whistle:) then finished it off with dog walk pulling the boy in the sled in heavy snow. Sometimes I think cold and snowy weather gets me more motivated to be outside than warm weather lol
