Severe WX Severe Weather Threat - December 8th-10th, 2023

Warm moist air from the gulf collides with cold, dry air from the north, along a jet streak that occasionally brings lit matches in the form of low pressure disturbances along for the ride. This is why dixie alley is like no other for severe weather. Location, location, location.
Right.
 
Saturday 18z GFS run maintains a tornado threat in Louisiana but shifts it slightly northwest compared to the previous run. This forecast sounding is from near the LA/AR border - which would of course place it perfectly in the Radar Hole™ between SHV, LZK and DGX:

That hodograph is pretty straight, and the wind barbs pretty unidirectional. That TOR hazard type is likely fueled by quite large CAPE for the time of year. The reason the ceiling isn't expected to be higher with this event is because that's largely not overlapping with strong low-level directional shear.

Thanks for the input. Since I'm not an expert at reading these soundings, it's probably a good thing I'm not a professional met - and if I was the NWS would have to change their logo:

(Still, the sounding analogs of April 23, 2000 and March 4, 1966 were enough to raise an eyebrow for me. Not saying we'll see anything remotely as violent as Candlestick Park 1966 tomorrow, but it was enough to make me wonder.)
 
Dixie Alley has been THE Tornado Alley over the last few years and why is that?

Well basically because we sit right on the Gulf, which means it doesn't take a lot of time to get moisture return like it does in the Central/Southern Plains.
 
Well guys, I got an underground tornado shelter installed in my yard in early November so I've got it if needed, but I'm hoping I don't have to test it out just yet. I still feel just as nervous waiting for these days to occur but the shelter does give me a little piece of mind.

We moved in July and we now have a basement. Not thrilled with the idea of being down there all night.
 
18z RRFS-A. I'm curious if anyone has any soundings from this model?

00Z HRRR with some potentially troublesome storms moving into AL in the evening. CAMs may flip-flop between now and tomorrow afternoon, but with the current presentation I'd be on my toes in the northern half of AL.

Hwy 45 corridor and Tupelo Mississippi is my primary chasing target tmrw. I may eventually work over to Northeastern Alabama.

I knew the models would shift but damn not this far East. Whatever. I'll be wherever the action is tmrw.
 
00Z WRF 2 Is ridiculous lol

The OG WRF model even shows substantial convection southeast of Jefferson county by 3 or 4 o'clock uh03_max.us_se (7).png
