With so many pro-Euro/GFS on this forum, I assume the 15z SREF can be disregarded since it doesn’t account for the suppression/Canadian low up top as strongly?

What does it show?  I think a lot of us are also watching some really bad basketball right now which doesn't help.  LOL.

I don't think there is a pro one way or the other.  The SREF looks like the 12:00PM NBM which I mentioned just a minute a go...SE jogged stopped on it.  But I believe 12z doesn't get ingest until 3:00PM.  I also mentioned this should possibly trend back NW.

Nino climatology favors a more coastal track.  I sometimes wonder if these models have had three years of Nina tendencies plugged into their programming.....Nino climatology is a bias east, but modeling refused for days to see that.  I would not be surprised to see the bullseye end-up being western North Carolina.  The Piedmont isn't out of it.

We do know each occurrence is ingested into the Model's. So, 3 Year's of Nina's.. probably so .

It is a likely problem, and I believe this is why we are seeing SE jogs this winter.  It is like all of the model trends that we knew for 15 years have been reversed.   Modeling has been well northwest of where it should have been - almost like a severe Nina bias.   It can even be seen in LR modeling.

Yeah, makes sense. Glad you thought of it. Good catch man.

Whoops. Sorry, I missed that update.

I thought Ninas normally favored suppression and out to sea, which to me would fit this trend. Aren't Ninas when places further to our south usualy get good snows? 

Where's that juicy Nino STJ when you need it lol. 

Nina storm tracks are cutters west of where an inland runner would be.  There are two storm tracks.  Primary is just to the west of the Apps or the Apps.  Secondary can be a slider.  The Mid Atlantic hates Nina climatology.  Weak Ninas can be decent as we pick-up the slider track.  During the past three winters, the track through the eastern valley has been a primary track which is why I mention it - if that makes sense.

NOAA runs two supercomputer system...nicknamed "Dogwood" and "Cactus"...ones in Virginia, one in Arizona. Currently they are numerically driven...but their replacements are being worked on that will change them to machine learning based. If the Enso states are being over done one way or the other, then a programmer changed their algos.

And it will depend on where one lives as to what trend they want.  LOL.  I do want the SE trend to stop, but I don't want much of a NW trend for MBY selfishly.  

I’m just terrified of the prospect of having brutal cold with no snow to show for it. May have to chase with the kiddos on this one.

She basically seems to be going with the NAM graphic and describing the snow to rain transition based on diurnal heating. 
Time stamp is around 6 minutes in. 

I never would have imagined we would have temp issues

Look, I get it, I'm sorry for her. No matter what happens she is going to have a bunch of idiots messaging the WVLT studio, harassing her and her family. I suspect she is trying to temper expectations for viewers. 

Something needs to slow the chatter never really seen anything like it.

OK, let's get back to work.  21-4 run to end the game, and a TN win.  The SE trend stopped in Athens!   Time to Knecht the cold with the precip and get some snow!!!!

I don’t blame her at all. However one thing I believe that would help the local weather people in these situations is to show the viewers more than one solution and explain the difference. At this range they could show more than one accumulation map.

This is why a lot of Mets ride the NMB. It's the safer route than picking a single winning model.
