3k NAM
![]()
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.
LINK
Given the above and the 12z Euro QPF below, 4-6" looks almost locked in for those along and north of I10/12. South of there will see more moisture but likely will mix with sleet. If the warm layer above the surface is stronger than expected then sleet mixing will push farther north, if it's weaker, then some bigger snow totals in the south. Good luck everyone

Where is the best place to go skiing in Baton Rouge tomorrow, or snowboarding? LSU Hilltop Arboretum/Highland Road Park Observatory?

You just pissed off a bunch of Houston baws with this post. It shows less than an inch there.

The LSU levees where they have the paved jogging track? Those are pretty steep.

I think I read 10:1, but rds cd can verify that
That’s what the model uses but not necessarily what actually happens. For instance, on the front range they had a ratio closer to 20:1

Snow could be 10:1 or 20:1 ratio.
half inch of water = 5 or 10 in of snow

My bad, my bad. I was only breezing through posts. Ok Houston baws, forgive me.

It still means less for us. South and east of Houston look to get more.

Cloud cover here in SW LA. Temp already dropped 3 degrees in the last hour. Down to 37 now.

OpenSnow is pushing 11:1, so 10:1 is likely going to be very close.
