That helps, it's a pure spacing issue with the wave behind and the wave off coast. It's actually more the TPV in SE canada that ends up squashing things. The ocean low phases with it. 

While the ULL diving south is closed and robust the trough axis is positively tilted.

One way we can still win is if the main ULL has more latitude as it heads east. I honestly prefer it NOT to dig too far South to begin with. I dont think theres enough spacing for this thing to turn a corner and ride the coast.

TL/DR: Strength and Latitude ftw 

 

CMC is quicker and drops the 500mb low right over us.  I don't see how that spacing is going to work for anything more than a clipper though.

I’d feel worse if an op does that. We are still a long way out.

It can still change but we’re probably about 24 more hours of this trend continuing from me putting the MLK weekend threat into the “highly unlikely moving on” category.  The trend we don’t like has actually been happening steadily for like 3 days.  
 

This was the look I really liked 3 days ago.

Look at the spacing between the trough digging into the central US and the through over the Atlantic. Also note the hints at a weak low over the Canadien maritime. Just enough to prevent cutting but not suppressive. Plenty of room for that to amplify but the axis of the whole pinwheel around the PV is far enough east I wasn’t too worried about a cutter.  Plus note there is stj energy phased up with the trough. That was a really good look. 
 

But look at the latest run.

Everything went the wrong way. The stj got left behind. The Atlantic trough trended slower and the one digging into the US faster. There is no space to amplify now. Look at the flow over New England now v what was advertised 3 days ago. They are all subtle typical errors for that range but they all went the opposite way of how we wanted.  If this spacing issue continues to degrade I don’t think we’re that far from this being in the very unlikely category.  Tomorrow it will be inside 100 hours.  Huge longwave errors start to become less likely after that imo. I’d like to see improvement by 12z tomorrow.

@CAPE

You guys remember back in 2015 the week leading into the superbowl in early Feb when there was a northern stream shortwave originally tracking from Indianapolis ESE into our area? We tracked it for about 5 days. Started off with a sweet pass south of us.Very unusual track with suppressive flow. That kept bugging me and sure enough, suppression backed off in the short range and it tracked north of us and destroyed Boston. 

This weekend reminds me of that. I starkly remember thinking to myself back in 2015 that if that type of setup ever shows up again, that shortwave better start off passing pretty far south in the mid range... we'll see...

Eta: that might have been the storm that inspired @Jebman to post the most hilarious rambling rant against Boston that has ever been written. Anywhere. Lol

I went back and dug that up a couple winters ago. Just epic. Instant classic, and maybe the best series of posts ever made here.

Yea often a day before an event we want ridging if there is already cold locked in. Note the look I liked a lot more has a lot less blue.

Thank god we don’t live at 10 mb. Plus it gets displaced in a few days then elongated and stretched in the long range. Furthermore it’s not coupled well to the TPV which is what impacts us a lot more.  The PV isn’t very high on my list of problems right now.

I don’t think this was ever gonna be more than a 2-4 clipper 

Got a high in the perfect spot, a 50/50 low and the shortwave is a well defined 540-546 split. This is usually how a KU storm starts, not saying it will happen though.

Uh oh, almost time to trot out "your" hamburger disco from last year.

These 2 have been fighting since 1999

Reel yourself in man. Kind of uncalled for to post this in here and everyone knows the vax is ill-conceived or at the very least ineffectual.

Everyone I know has stopped taking it unilaterally but they already got most people early on.
