I haven’t heard it but that’s way too early especially with plants letting out between 4pm-6pm. I could see them closing it after that say 8pm.

MSY will be closed tomorrow. They already started cancelling flights about an hour ago for today going forward. You can still get a NetJets flight in though.

Flightaware Misery Map shows that
83% (and increasing) of flights that were scheduled to leave MSY tomorrow are canceled
73% (and increasing) of flights scheduled to arrive at MSY tomorrow are canceled
Bush and Hobby have similar percentages

Here's my thinking on snow totals as of 3 PM Monday. Keeping an eye on guidance & some potential that I may have to nudge higher totals a little farther south.
Still think bands of 8"-12" are possible but nearly impossible to predict.

90% will all be locked down at 530 today.
I’m one of them

In Calcasieu 1 app says 6-8 another says 4-5 and another says 4-8. Like I said anything over 3 I’ll consider myself lucky.

12z 3k NAM looks realistic, given the setup. It might be a bit overdone, but there will likely be a narrow band of heavy snow across South Louisiana. There will be warm air advection across South Louisiana - Red Shading (that will drive a warm nose over coastal areas), and there will be strong frontogenesis -Purple Lines (that is indicative of strong forcing for snow production). Smaller scale processes will drive the final location of the warm nose and the best snow production, and the global models can't resolve these. The HRRR and 3k NAM are probably your best bets moving forward, and even they will struggle with the final placement.
The above still holds, now for a bit of nuance. The 18z 3k NAM and HRRR show heavy snow banding setting up with potential convective elements. Where this banding sets up will determine who sees bigger totals. However, what if it sets up just offshore of SE TX, like the 18z HRRR? I wouldn't want to be on the hook for the Houston area forecast
Whoever gets one of these bands over them will probably see historic totals, while areas just to the NW won't see much at all.
3k NAM
HRRR
Now, what if you lived in CENLA and you've gone from this forecast graphic to the 18z runs? I'd burn my house down! (not really, but I'd be bummed)
I do, however, like the balls of the Lake Chuck office to go out hard early on.
