18z GFS looks similar to 12z CMC. Screw the Euro.

 

It looks a lot better. The ns vort is weaker and never pops a low. All guidance today had it in some fashion.

 

The clipper turns into a 50/50 as well. All we can do is pray. We know precisely what to look for...the absence of the midwest low.

This already is a good forecasting run last 4/5 days and will continue to be. Models, already very erractic and inaccurate this season, will reall be in the multiple outcome every 6 hour mode if we continue with the clipper-phasing-coastal scenarios.

Well at least this time there's no clipper redevelopment BS and hopefully no damn GLL low to screw us.

Yeah the 50-50 low would work out nicely if we can get a transient, well timed block up north to trap it underneath. There are some hints.

The clipper closed off and crawled away and the ns vort was weaker. I saw it early on. Better confluence and no low in the midwest is key on this run. 

 

Exactly.  This is the look we need and it has appeared before among the other solutions.  18Z with the big high in western Canada extending/draping down through the Lakes and into the east rather than the GL low or narrow split in the high allowing a low to develop there  Notice how in the 12Z run at 120-h (valid 12Z Sunday), the inverted trough from the low near the Gulf/south TX extends up through Michigan.  At 18Z for the same time (114-h), that inverted trough is "cut off" more by the Canadian high.  I sure hope this is what actually happens.

 

La la lock that sh*t up RIGHT NOW.

 

No kidding!  If only we could.

interestingly, the GFS had a blizzard for NE about 5 days ago, lost it by having the vort pass to our south, then got it back, albeit in a different fashion than the original blizzard

 

at this range, we just have to expect that the models will be somewhere in the ball park, whether it's the bleachers or box seats we'll never know until it's over
