Tennessee Valley and Southern Appalachians.

Some absolute monsters on that 12z EPS.

Not a single mention of the destructive, likely significant tornado in the northern suburbs of Birmingham (Fultondale/Center Point) tonight?

Also can a moderator change the title of this thread, considering it is certainly no longer 2019?

Did some skimming of SSTA data tonight and I'm intrigued by that warm pool centered at ~150˚W and 30˚S to the south of the cold SSTAs with the Nina. Based on looking into some previous analogs around this time, it seems like that strong meridional dipole is not present in years such as 2006, 2009, 2012, 2017, and 2018 (generally quieter severe seasons especially late season). It is more prevalent in several big Nina springs though, including 1974, 1976, and 2011. It's probably to some degree why this CDAS-derived SSTA analog product from Tropical Tidbits is essentially grouping a who's who of Nina springs with a lot of tornadoes/severe weather, including some with very large outbreaks. You can see the SSTA dipole present in the Southern Hemisphere in the mean here.

Can you both take your crap to DMs?

Yes. This is exactly it. The confluence between the TPV dipping southeastward into Ontario and the SE ridge downstream.

The reason for lower totals further east is because of the shearing of the parent shortwave and resultant partial loss of dynamic support with time. This has nothing to do with temperatures.

The January 67 blizzard was not a phaser. It was one shortwave (more amplified than this one, but it was not a Jan 1978 type scenario).

No, it isn't. Stop clogging up the thread. This system has never been a "phaser" and it doesn't need to be for foot plus totals. The reasons why have been discussed ad nauseam over the past few days, but you continue with this borderline trolling nonsense.

2015? Sure. 2011? Not a chance in hell.

This. That would mean there's barely a shortwave left due to confluence from the ULL/TPV and the SE ridge, there would barely be a "brunt".

I don't really see how one can establish a "trend" when models keep flip-flopping back and forth, nor can I see a solution where Indianapolis gets the brunt of this.

This thread is a ****ing trainwreck right now.
