I'm not really sure it'll be icy here in downtown with the temperature this warm on most models... but I really didn't look much today since I'm enjoying this warm weather in Clayton, NC :)

 

Sref plumes have precip popzr above 50% for monday.  Nam showing some icing also.  Not saying its for sure going to happen but everyone here wants an update until its not what they want it to be.

I understand your frustration, man. Sometimes I wish I have little more meteorology knowledge so I can spam up this topic but eh...

 

18z NAM is an ouch for downtown Asheville, but only for like 6 hours rather than 12 like 12z NAM was showing:

Frisk... their latitude really helps them up north.  They are simply just closer to the cold air source and don't have to rely on cad or a ULL to produce big snows.  Cad is usually the reason why we get icing down here.  When high pressure funnels in cold air from the north and backs it up against the Apps, temps drop until a storm approaches.  The warm air associated with the storm moves in over top of the cold air provided by the high.  As precip. begins to fall it may be rain in the upper atmosphere but if there is a layer in the lower atmosphere below 0 degrees celsius or the surface is below zero then the p-type will be sleet/zr.  Depending on how cold that layer is below freezing will determine if the rain becomes sleet or not.  Also our storms are typically gulf storms that have strong, warm, winds from the south, where as the north receives winds off of the much cooler Atlantic during their storms.  Hope that explains it somewhat. sucks.

 

Blue... no worries I am no met either, just studying to be one and I like to hear other peoples thoughts because I have learned soooo much from this board.  These type situations are the ones I know the least about predicting so I really want to hear some insight from those who know exactly what to look for.

Thanks, man :) I really don't see anyone in NC getting snow out of this storm unless you're on top of mountains because of that warm nose being too strong but someone is going to get bad ice storm. Chances is pretty meh for ice storm here in Bumcombe County but we'll see.

well it looks like buncombe county is left out of this wwa also.  never have seen a winter where the low lands have more winter weather threats than the mtns.  buncombe county is in the mtns. as well as all the counties west of buncombe.  can't quite figure this winter out.  would think even buncombe with the elevation would be in on the wwa.

My anemometer is a little worse for the wear after a Winter of hurricane force winds and rime ice. (Note the cups are bent )  I think it is about time to replace with a professional setup that automatically transmits data to the cloud so to speak. Looking forward to Spring..

 

(No comments on the potential ice setup that is coming since this is the mtn snow thread.)

Classic elevation event: 12Z NAM follows 06Z trend, better for NW NC ski areas (4,000 FT) snow tonight and Monday compared to 00Z. Models have struggled a lot with the back two pieces of energy, scheduled for Monday and Tuesday. Tuesday CAD ice right up on the east face of the Blue Ridge is still possible with all the model waffling. However I'm more interested in snow up at the NW NC ski areas tonight and Monday. 

 

A few hours of drizzle would not surprise me on mountain peaks this afternoon and early evening. If multi-layer clouds depart temporarily the low clouds will sit below the dendrite growth zone. However multi-layer clouds are forecast to return tonight, along with at least light snow. 12Z run forecasts colder 700 mb temps tonight and Monday in NW NC. Also 546 thickness is plenty low enough for mountain snow. Again I'm only talking above 4,000 FT in NW NC.

Mt. Mitchell reported 3.5" of snow yesterday for a season total of 120" at the 6200 foot level. (Rangers quarters.) Seasonal average is a little over 100".  

 

The second highest total I could find was 76" of snow at Sugar Mtn. (Pretty sure that LeConte has had more than that but less than Mt. Mitchell.)  The highest total I could find in West Virginia was 157" at Canaan Valley. 

 

My mtn top has had approximately the same as what has fallen at Cataloochee which is about 35".

Starting to get some reading around 26 to 27 along the escarpment in Avery County.

 

Snow/Sleet mix going on over in Blowing Rock areas

 

WUNE Grandmother Mountain is 26 degrees where Grandfather Mountain Summit 1800' higher is 35 degrees.

Hawksnest is 25 degrees

 

Also noticed several 24 degree readings in Alleghany County and a 24 degree reading at WUNL at Sauratown Mountain north of King.

Alright my mountain gurus.....looked at several forecasts for the Boone area for Wednesday.   Thinking about taking my kid up for the day to ski......most of the forecast call for a chance of rain Wednesday morning .  What say ye?  Any help would be appreciated.  Have to figure out by this afternoon!!!

Ok, so Bumcombe County is under winter weather advisory for ice/sleet and black ice... interesting.

Same for all the southern NC border counties from Transylvania to Union and north of there between Haywood and Davie. Though I can understand the advisory being through 11:00am tomorrow for the mountain counties, are the temps expected to be that cold to support the advisory for Mecklenburg and Union?

You guys are colder then us right now.  You have better placement currently for the CAD that has set up.

Taking each state seperately, on an annual basis, what would be the snow hot spots in TN GA NC and VA.Thx for the info and had always wondered about Mt.Mitchell. Thx

From the WWA,

 

...THE HEAVIEST PRECIPITATION CONTAINING EMBEDDED AREAS OF

SLEET IS EXPECTED THIS EVENING.

 

 

Where is this precip going to come from, looks to me everything is already east of us.

i agree, where is the precip coming from.  when you look at the radar the moisture is already east of us in the mtns.

Parts of Roan Mtn are likely the snowiest for TN/NC. Some recent weather research instruments up there seems to support this. For Virginia it is Mt. Rogers although far Western Highland County along the WV border might be close. Not sure about Georgia.
