We had on & off bursts of moderate snow today. No accum. but, pretty to watch though. One thing I can tell is it's windy and cold....28.0° in Weaverville,

Yep same here Don. I thought the moisture in TN would make it over the mountains but I was wrong. Nice to see the flakes flying though. Windy with temp of 23 degrees.

Merry Christmas mountain folks! Hopefully a couple of you are enjoying a powdered sugar christmas. I believe we will have a lot more to post about in the next couple of weeks seeing as the indices seem to be going somewhat favorable. I am excited to use my new infrared thermo to check road and grass temps. I believe that if we can pull the -nao predicted for jan. and the jetstream will track lows from the gulf across the panhandle and to the nc/sc coast, we here in the mountains can really cash in. Lining up a couple of crucial blocking's has been painstaking over the last few years but it looks like we might have a window opening. On that note

Met..passed through on I40 overnight.and yes there is some snow on the ground in Haywood County near the TN border...almost enough to qualify for a white Christmas..very nice! Merry Christmas!

Ya it was very nice Christmas eve. We had some heavy burst of snow.

 

Nice cold Christmas morning here in Weaverville. Got down to 14.5°.........Hope you all enjoy the day!

YaDon we dot down to 9 yesterday morning. It was nice it felt like Christmas.

I think we could see several different opportunities for snow over this next month.

NAM shows the beginning of an ice storm here in the mountains early new years eve with the temps aloft crashing. GFS says nbd just a couple showers here nothing to see. None the less GFS shows a nice hit for us on the 1/2 & 1/3 storm so I have a good feeling we will be talking about something frozen pretty soon!

Ya I think we may get a couple of upslope events the next ten days.

Not to hijack the mountain thread. But if the NAM is correct then it will be too warm for ice in the mountains... if fact the overall setup no ice period. Looks to be a R>S system with the top down cooling.

Ah thanks NC.  Just finished my first semester at Mississippi State so I am still learning how to exactly read things.  I figured I would throw my opinion in for a critique.  How does a system like this compare to a warm nose that causes icing?  Does it have to do with the storms tilt as it comes ashore?

I may not be entirely right but to an extent yes. More of a factor is the placement of the ULLs. Which my climo is different from yours so its hard to compare. But generally you want the ulls to be close enough to each other so the thermal profiles are close together. Typically what provides ice in the piedmont is a miller b setup... which one low(surface and 850) typically goes along the mountains while transfering to a coastal but there will be a sw flow aloft caused by the 850 while having a hp pushing in cold air at the surface. 

 

Maybe there is someone more knowledgeable to explain it better. I can honestly say writing in life has not been a strong hold of my... Ive always found it difficult to explain my thoughts on paper. But if the nam is right then this will be a cold pocket aloft meaning below freezing from about surface all the way up to the top of the clouds.

Thanks NC I appreciate the explanation.  What your saying makes a lot of sense and I agree the sw flow plays a big part.  It will be interesting to see how this all plays out.  I would imagine if this scenario manifests itself, those above 3500' will stand a much better shot at accumulating snowfall then the Asheville area which lies aprox. 2000' & 2200' above sea level.  '85 tends to be 6-8 degrees colder then I am on a typical day, so he could have blizzard conditions at his house 30 miles away and there will be clear skies over downtown with 0% chance of snow.  Maybe we can get MikeGold to post a Bufkit analysis, I always enjoy looking at those because it gives us a better idea of what elevations will see what precip. type.

Was thinking the same thing '85.  Today would be a perfect day to drive up the parkway and sit at an overlook to see a little snow!  Too bad it is a Monday.  I am looking forward to seeing how cold this airmass is that has been modeled.  I saw a couple of maps that had Boone barely making it into the single digits.  It will be interesting to see if this verifies.

Ya I think this air mass could be one of the coldest air masses we have seen in 2 years. Will be interesting to see how it all plays out.
