Brad Travis mentioned something about a possible winter storm next weekend across the South. Anyone seeing any signs of that? I'm supposed to travel to the D.C. area Friday.

There was a couple runs off the GFS flaunting some wintery weather but being both 140+ hrs out & GFS not consistent, held off on mentioning it. Euro shows a nice disturbance but it's got a different track with no secondary low off the GA coast like the GFS had. 18z GFS more in line with the euro & doesn't bring snow or ice to the TAG region. Confidence is low but there's a possibility.

Keep an eye on that ULL that models bring over the area late Friday into Saturday. Backside deformation band looks to change over to snow.

There is quite decent model agreement, I like the potential.
If the GFS is right with the speed of the cold front, there is a good chance for accumulation for TN & N AL. If the euro is right, a large area could see a nice dusting still.
NAM looks the best though for a weenie!

Warm nose depicted on NAM sounding brings HSV close to sleet & freezing rain territory. Still plenty of time to see a warm trend, cold trend, low disappearing trend, speed trend up, down, etc...

FWIW, CAL from UAH is not impressed AT ALL with this setup. His thinking is this is a very poor setup for snow even if the models show accumulation.

The trend to keep the trough open instead of closing it off is lowering significant wintry precipitation chances for AL. I do still think there will be a small changeover on the backside, but it’s significantly less of a snow event it once was showing up as.

Absolutely, this would be magnificent if it were a Dixie alley cut-off low, but that's looking more unlikely every run.

I’ll be traveling to Maryland tomorrow. It should be mostly rain along I-81. I don’t think the precipitation is supposed to change over in East Tennessee until sunset.

Latest model runs have shown a dry slot keeping most of north central/east AL from seeing much wintry precipitation (sleet, freezing rain, snow). As is often the case, I think we'll see the occasional wave of flurries flow through, which may give some of us a nice dusting.

I’ve been tuned in to Fox 13 in Memphis. No major reports of issues in Memphis proper but reports of bridges in rural N. Mississippi icing up.

So far the only "event" I've seen was a brief burst of snow in the Gate 8 of Redstone Arsenal just before noon.

Not sure how far east the deformation band will travel but my thinking is that it'll likely dimish around limestone, but may still produce decent flurries through Marshal county. Travelers beware of black ice, it's still wet out there and the temperature is dipping below freezing rapidly. I'll be one of the unfortunate few who have to go to work in the morning :/

Luckily the wind is blowing and helping the road surfaces dry.

According to the post made to a trucker group this is mile marker 120 on I-40 in western Tennessee.
