Wintry Nov 30-Dec 1 Flurries/Snow Showers

Tomorrow afternoon-early Tuesday morning continues to look more interesting. I am especially interested in those bands being shown on both the NAM and RGEM. If they do happen I wouldn’t be surprised to see a brief period of light-moderate snow. One thing to watch will be how the temperatures react tomorrow. With how cold the upper levels are( -4 to -7C at 850) I would say we will probably be supportive of snow around surface temperatures of 37-39 degrees. Hoping we can sneak in some flakes before sunset, but either way I think quite a few people on here in North Alabama and Georgia got a real good shot of seeing their first flakes of the season!

I 100% agree. These bands are going to be super thin but could rip snow for a few short minutes. Don’t be surprised to see some isolated reports of a quick dusting under those heaviest spots.

will be very isolated though. There is a ton of moisture at the 850mb level and I find it very hard to believe that it doesn’t break containment.
3km nam has been the driest of any model so far and even it has snow showers breaking out of the mountains.

Someone correct me if I am wrong, but the 12z HRRR was also interesting looking at the simulated reflectivity. Almost looks like there is a convective nature to those shower/snow showers.09B35A5E-8CE1-4A0C-AB6B-AB67941F1B53.png
 
I really do think people east of the mountains have a chance at a flurry. 3k and GEFS and I think HRRR have all shown activity in central/east NC and a bit in the upstate. Low chance, but I don’t think you can rule out flakes

Some bright bands showing up against the mountains in E TN

yep and these convective streamers can be a blast. CAN be. I’m not trying to over hype this. But they can dump some snow.

here is the WRF-ARW. That tiny streamer drops 1-2”

but it’s 100% just a wait and see what happens type of event. Completely random

Call me pessimistic, but I just don't see that happening anywhere east of the mountains. NW flows hardly ever produce the goods here unless we already have the cold air in place. Or maybe a random clipper. But even then, we still need the cold air in place. That's one of the many negatives to living east of the apps, unfortunately. By far the most painful example was December 2017. Never want to relive that crap again!
