Liberty Texas storm has gone tornado warning. Also Spc night put out high risk in the next few minutes 

They may have to extend the risk areas further west because of this

 

Also, the media will go crazy if there is a High Risk.

Moderate risk maintained, Kind of how I figured it'd go, here's the updated discussion.

SPC AC 291959 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0159 PM CST Tue Nov 29 2022

Valid 292000Z - 301200Z

...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT OVER PARTS OF NORTHEAST LOUISIANA...EXTREME SOUTHEAST ARKANSAS...CENTRAL AND NORTHERN MISSISSIPPI...AND NORTHWEST ALABAMA...

...SUMMARY... Strong tornadoes, very large hail, and severe wind gusts are forecast this afternoon into the overnight period across parts of the lower to mid Mississippi Valley, Mid-South and parts of the Southeast. ...20Z Update... A regional tornado outbreak still appears possible from northern LA into central/northern MS and potentially into western AL. Rich low-level moisture has streamed northward with the aid of a strong low-level jet, as steep midlevel lapse rates (greater than 8 C/km on 12Z SHV sounding) have overspread the region from the west. MLCAPE has increased into the 1500-2000 J/kg range across the warm sector, and storms are gradually increasing in coverage and intensity across parts of LA/MS. Strong and favorably veered wind profiles will support several long-lived supercells late this afternoon into this evening. With relatively weak low-level lapse rates, it may take some time for storms to become tornadic, but a few long-track strong tornadoes will be possible late this afternoon into tonight as supercells mature and move northeastward. The primary change at 20Z is to expand the Marginal Risk slightly eastward across a larger portion of western GA, southeast AL, and FL Panhandle. This change was made to account for the possibility of nocturnal storms reaching these areas prior to the end of the forecast period at 12Z.

I'm getting really old data on the correlation coefficient out of Jackson (Radarscope only) - this does not have a confirmed tornado as far as I know

Looks like super-res correlation is down on KDGX, you'll have to use what little regular correlation coefficient has to offer

SPC mentioned it may take a while for the storms to fully get going due to weak lapse rates, and so far that seems to be the case. But it does look like things are starting to ramp up a bit with one confirmed tor and a few other cells that are starting to look dangerous

Things look to really be ramping up in Louisiana, pretty worried about how many discrete storms are popping up with relatively decent spacing... 

Also the Tullos storm has been tornado warned.
