Pattern December Dud đź‘€

The 20th - 24th threat definitely has some legs. Again the biggest problem is things moving too fast as I said before. But given we’re 180 or so hours out .. we’re only a few changes away for something bigger for the SC, NC mid Atlantic folks..

It’s all about timing with this one. It be a great time to have a giant -NAO block right about now lol
 
The CMC has cooked up an interesting look at the end of its run. A building CAD with light overrunning precip.

A bit more entertaining than usual given that's Christmas Eve.

I tried to look for something to hate about what the Canadian is selling here at the end of its run but I couldn’t. Shucks. Legit cold air modeled into SE Canada.IMG_0632.png
 
The Pacific onslaught on this GFS run is just insane. The MJO alone isn’t going to fix that problem. The MJO moving out of the Maritime Continent and across the Pacific (6-7-8) is a process that adds momentum into the Pacific Jet. Having the jet already energized isn’t a good starting point. So, we need to take a step back there before we can move forward. Something has the jet really energized so far here in early winter. You can see here on the 2nd image where the subtropical jet along 30N was weaker than normal from late Oct to early Nov, but has been stronger than normal since late Nov. The MJO has been in 5-6 during that time, not where you would expect to see an extended Pac Jet. Also, there hasn't been strong + East Asian Mtn Torque either. * Throws hands up *

Model could just be wrong. I haven't looked at what the other models are showing, though.

There, found it for you lol. I am so sick of 240 hour maps. I still sincerely wonder what type of error keeps occurring in all NWP that always results in these wildly wintery looks for the east and southeastern US that never come to fruition once model error decreases (i.e. shorter lead times).
 
Winter getting into "February" mode quickly...at least it's cold in Florida #sarcasm...

I honestly think the GFS is out to lunch here. This has been the theme so far to try to bring the warm hounds in the extended only to reverse as we get closer in time. Let's see how this goes the next few days before we worry about can kicking.
