Sneaux next week [Historic snowstorm in southeast Louisiana on January 21, 2025]

And -- at least in SE Louisiana -- it will remain cold enough for about the next ~40 hours that the snow will stick around for two or three days ... Might not be gone-gone until Friday.
Thinking on this some more ... I'll lay my chips on Saturday, early afternoon. There's a lot of accumulation to clear out -- I can see some icy/snowy nooks and crannies lasting into the weekend. Saturday highs are supposed to be north of 65F, so that will certainly finish off the rest of it.

EDIT: What faceman just said.
