Once again allow me to apologize for the tardiness of the post here. Still dealing with the wintry weather across the area. Luckily our forecast for SE LA was pretty good as the freezing line remained just to the northwest overnight. Lots of ice though from Baton Rouge westward and then some snow up along the I-20 corridor around Shreveport. We also had some thunder and lightning earlier, along with some of the sleet and snow flakes mixing in with the rain. What a crazy system! Thundersleet is pretty rare for anybody, and especially down here. Just a really dynamic system as the surface low works it's way south of our coast and then begins to turn up into the Carolinas
Of course rain is overspreading the Carolinas as we speak. There is a freezing rain advisory for much of western North Carolina until midnight tonight. While I don't expect this to be a huge issue . . . as we mentioned yesterday some of the colder spots and elevated road surfaces could get slick at times so be careful driving around tonight. Most of the area right now though is above freezing so that is good news. After rain tonight and the first half of the day on Saturday, things should clear out in time for a nice Sunday.
The next chance of some showers will be on Monday however this system looks fairly week. What's interesting is the potential for another massive shot of arctic air by the end of next week. Take a look at this . . .
That is the GFS surface forecast for 192 hours which is next Saturday morning the 12th. Now granted this is still over 7 days out, and I never really trust any model or forecast over about 3 to 4 days. However what's important to note here is the large arctic high over MS and AL, and the -10 Celsius degree temperature line down into the area!!! That is very cold air, as the freezing line is pushing all the way into the gulf. Now again this has several days to change, but if this were to happen it could be some of the coldest air this season. Certainly will be something to watch.
Ok that does it for me today. I hope everybody has a great weekend. I'll try to jump on for another update tomorrow or Sunday as Matt will be driving back from Disney on Sunday.
