The 0z GFS is just NASTY! It is the El Nino winter weather we have been waiting for since November.
The GFS shows the cold front that is currently to our south, moving back north as a warm front tomorrow. Meanwhile, the first of a series of shortwave troughs rotating around a positively tilted longwave trough over the Rockies will begin to effect our weather on Wednesday with a shield of rain. The first round of showers ends by late Wednesday night, with a break in the rain until New Years Eve night. The GFS then shows the next disturbance moving in Thursday night with rain engulfing the area south to north as New Years eve night. While this is going on, a reinforcing shot of shallow cold air advects into the area.
The 0z GFS show temperatures hovering in the 40's for the majority of SE Louisiana on Friday and Saturday as the train of disturbances trigger numerous showers for our area. It doesn't appear to be a flooding event by any means though with rainfall totals through Sunday totaling 1-3 inches of rain on the South Shore and 1-2 inches on the North Shore. But if your doing anything outside after tomorrow, it looks downright miserable.
Good news at least in my opinion is that it appears the AO may begin to dropdown pretty well. Still have to see if it really does as forecast. If so, then any effects here down south will around the middle of January about when we would want. Just need to keep the STJ active.
What? You're going to another site for winter forecast fantasies? Shame on you, lol ;)
You know this guy likes to blow it out of proportion when the jet stream graphics he draws is nothing close to what the jet stream will look like this weekend, he has the polar jet stream all the way down to the gulf coast when is only the subtropical jet stream in your neck of the woods lol.
The most recent runs of the Canadian and European ensemble packages show potential for cross-polar flow and a Siberian intrusion, as well as the threat for a significant, or worse, winter storm affecting Texas, the Old South, Appalachia and the Eastern Seaboard. Cold air makes its first meaningful push January 6-8; the chance for widespread snow and ice (maybe rain thunder along the coastlines) is targeted for January 10-14. Given the impressive stratospheric warming event and inputs from tropical forcing, I suspect this tendency for widespread cold and increased frozen precipitation is going to be around for a long while.

coffeecups: Came home to Harvey from Slidell. Had a little rain here and there. There was no rain in Slidell when I left at 3:30pm. While in NO EAST, I saw where it looked like it was storming around Covington going towards Slidell. Wet but no rain when I got home

coffeecups: I will eat some strawberries on my cruise in early May---just a few of course, as long as I stay away from my better half.

coffeecups: I'm hoping that I don't see any 'rare' rain events here.

coffeecups: ps I guess the memory of that snow is probably the only winter that I will get.

coffeecups: Somewhere around 1956 and 1958 it snowed so much that I thought I was in a blizzard. Of course I was only a child then, but the memory of that has NOT been met or surpassed.
