Now it appears to have the potential for supercell development ahead of the line (for AL on Saturday). If that trend continues, it wouldn't be surprising to see the SPC expand the Enhanced area farther north, covering the large majority of the state of Alabama.

Yeah, and along with an expansion of the enhanced risk, I would expect to see a moderate risk in there, as well. Again, that’s if the tornado probabilities, particularly with discrete supercells, increases.

ETA: based on model trends and discussions on weather message boards I read, I definitely think the chances of discrete supercells put ahead of the squall line is increasing for Alabama on Saturday. Of course, these would be the ones with the best chance to produce tornadoes, maybe even a few EF-2+ type tornadoes.

It's for sure increasing. Last night it seemed that the risk was more for winds than tornadoes. You on weather forums only or do you do discord too?

Right now, it looks like the highest tornado threat will be along I35 tomorrow before things line out and then on Saturday as the system moves into Alabama. It looks like mostly a squall line type setup for Louisiana and Mississippi.

Steve Caparotta said New Orleans Office thinks some parts of our area will get upgraded to a Moderate Risk for Saturday.

Question:
If the line speeds up, which some mets have mentioned could happen. Would that hamper super cell growth out in front? I don't really know if a faster squall line would hinder or help. Of course, if it could get through the area (AL on Saturday) prior to afternoon heating one would think there would be less instability.

Really? So NWLA has a less chance of a tornado outbreak than Texas and Alabama?

Hatched means they thing the risk is significant. It's called that cause on the probailistic map they put hatch marks.

Mesoscale Discussion 0008
NWS Storm Prediction Center Norman OK
0453 AM CST Fri Jan 10 2020

Areas affected...Central/Eastern AR...Far Northeast
LA...Northwest/West-Central MS...Far Southwest TN

Concerning...Outlook upgrade

Valid 101053Z - 101300Z

SUMMARY...An upgrade to Moderate Risk will occur across
central/eastern AR, far northeast LA, northwest/west-central MS, and
far southwest TN with the upcoming 13Z Convective Outlook.

DISCUSSION...Based on recent guidance, the probability for
significant wind gusts (i.e. gusts at or above 75 mph) to occur late
tonight into early Saturday across northeast LA, central/eastern AR,
far southwest TN, and northwest/west-central MS has increased. This
increase in probability merits an increase to Moderate Risk, which
will occur with the upcoming 13Z Convective Outlook. This expanded
Moderate Risk will include Little Rock, AR and Memphis, TN.

More details regarding the meteorological conditions will be
available within the outlook.

.South-Central States...
An outbreak of severe thunderstorms is possible later today through
tonight, with the most dangerous portion being tonight into early
Saturday morning with a potential derecho and embedded strong
tornado risk.
Primary changes this outlook are to expand the
Moderate Risk east across the Lower MS Valley and increase tornado
probabilities for the evening/overnight period.
