December 12-14, 2022 | Significant Tornado Outbreak

[Neoncyclone]

Oh boy, this is one of those couplets that scream strong tornado, especially if it gets any worse, just SE of Rising Star, TX.

[Neoncyclone]

Luckily no debris ball so far, must have been a mean looking meso

[Neoncyclone]

Confirmed tornado just passed south of Decatur, TX. Couplet still strong.

It's now PDS Warned

Impressive storm system to say the least.

Confirmed tornado entering the heart of DFW now

Really solid debris ball on it too.

Literally told my co-worker that also lived in DFW for a while that Watauga always seems to get tornadoes. Hopefully it's very short lived.

Looks like it was, debris ball looks more like debris fallout now

Got ~1.5 inches from this squall line. I haven't checked the Rain Gauge yet.

Tornado on the ground in Grapevine, TX!

Yet another long duration outbreak 🙄

[ClicheVortex2014]

The latest HRRR rolling in looks disgusting for east Texas

[ClicheVortex2014]

Watching this one for sure

[ClicheVortex2014]

Definitely not surprised severe storms/tornado warnings popped off around DFW. Classic loaded gun sounding.

0-3km SRH looks like it would be 300+ instead of 1394. and I wonder what happened with the calculations for CAPE and so forth (the 9999's)

I’ve been watching this one since the beginning of this loop. That little hook when it was a “squall” is a good giveaway that, in a favorable environment such as this, a supercell is about to develop

Yeah some soundings have been glitching like that for a while now. Seems really random. Sucks, but after a while as you know, you don’t really need to know the exact values to know how favorable a sounding is

You really hate to see these in the winter. Hopefully it doesn't get too bad

[ElectricStorm]

Looks like they almost upgraded to moderate on the new outlook but they mention they wanted to see better instability

Hrrr is showing 1000-1300 sbcape so that’s understandable. But if it’s underestimating moisture then they might have to pull the trigger later. The next shift might also have different opinions.

[ClicheVortex2014]

No more active severe warnings. We’re transitioning from the morning convection regime (along cold front/near warm front) to cold front/warm sector… shown well by LWIR. Got new cells slowly developing in both areas.

[ClicheVortex2014]

Kinda have a secondary warm front moving north. It has dew points in the upper 60s with clearing clouds. Currently in the southern fifth of the enhanced risk

[ClicheVortex2014]

New MCD says they’re considering a PDS watch. Good sign that they’re still considering a moderate risk upgrade. I don’t remember ever seeing a PDS tornado watch with anything other than a moderate or high risk. 

[ElectricStorm]

They still kept it at enhanced on the new outlook, definitely would be unusual to see a PDS watch for an enhanced risk. I'm sure there are others but I distinctly remember a PDS watch on 5/22/19 for a enhanced/slight risk area in OK. Another PDS watch was up for the moderate area that day but that's the only one I can think of
