How is there this big strip of blue over Nola when everything else around it is a nice glob of purple. I’d be so mad if we got three inches and LaPlace gets 11 or something nuts

That model shows big drops north and south of Lake Ponchatrain

Rds, Is that a lake effect for both the north and south of lake?

That much snow will cripple Lake Charles.

This whole storm is setting up just like the one in Shreveport in Feb 2021. Beautiful fun snow then it melted and iced over. That is when all hell broke loose.

Good luck to everyone.

PSA: Use the hi-res models from here on out.


How does that differ for those of us that like looking at the pictures?

Yep everyone will get a rude awakening when the fun wears off if we get 6+ inches

This yellow area was the sweet spot for significant snowfall of most of the model runs for an entire week leading up to the NWS issuing this graphic Saturday morning. Now the entirety of the yellow shaded area all seems at some risk of not seeing any significant snowfall at all. Definitely going to be some FOMO for some folks in this area who were hoping for snow.

Yeah, people expecting 6+ are going to be disappointed. Of course folks will exaggerate and claim they got a foot


And let’s be honest how this will play out on here. For the areas that get more than predicted we might get five people on here bragging about being correct. For all the areas that don’t get near the top end of the forecast, there will be 50 chest beaters on here saying how they predicted it.
People are strange.

It doesn't. I still look at the snow maps even though I know they won't verify. It's a sickness

So why use the high resolution ones instead of the globals now? What is the difference?

Also, I believe the GRAF high resolution is still showing upwards of 9"-10" in the BR area, right?

Seriously, just use the 10:1 assumption on the snowfall. This is going to be very close to that.

I fall in the 6-8” range. I have a low graded metal carport and patio so I’m keeping my rock rake and ladder handy in case I need to start pushing snow off the roof. I’m worried about all the weight. Just a thought.

I applaud Lake Chuck for going big right out of the gate. It would have been easy to look at known model biases and climo for this setup, and just broad brushed a possible 2" and adjusted from there.

The smaller scale things that will drive snow location can't be resolved by the global models. I guess the GRAF is hi-res. I just know that it appears to be wrong more than it's right, based on what I see posted on here.

511.org cameras show red, but the closest camera traffic is still flowing.
