This is the snow depth for January 7 according to the latest GFS run. At this point, this would be similar to the 2008 snowstorm in some places however it would be below freezing for most if not all of Southeast Louisiana and Southern Mississippi. The latest GFS run shows temps anywhere from the low 20s on the northshore to the low 30s near the coast. Consistency is our friend at this point. This is I believe the 5th or 6th model that has shown a winter weather event of some kind affecting the Gulf Coast during that time period. Let's hope it stays consistent.
Wouldn't mind a bit of snow - just a bit as we don't have the resources to deal with clearing the roads etc if more than 1-2 inches fall.
But ice? Please no. That last ice storm in 2014 was deadly. My sister was nearly killed in an accident outside Picayune (and is still not completely well; she suffered a very severe concussion). And later that night some members of a family didn't survive an ice related crash a couple of miles from my sister's accident.
Some cold weather would certainly be appreciated. It is entirely too warm right now.
I don't trust winter models that predict snow or ice for our area until a day or 2 out. Remember Don't remember if it was winter 2013 or 2012. They predicted all week up until a day before the event ice storm of the century all the way down to the south shore. And we would see snow. It did get quite cold and I remember having icecicles on my mailbox. It lightly sleeted that day. And we briefly saw very very light flakes but nothing more. Some areas close by did see snow. But it seems Thibodaux always lucks out in recent years. Even 2008 snow was literally 10 miles from me and it missed me. And I had to get to work that day in Houma and didn't have time to drive to see it. Of course no snow in Houma that day.
