FLweather Posted November 25, 2013 Share Posted November 25, 2013 Looks the same overall through 39. SLP around or just SE of New O,LA with surface warm front in S GA stretching along or just of the SE coast. Rain all the way up the coast. Still shows decent CAD sig.

CAD_Wedge_NC Posted November 25, 2013 Share Posted November 25, 2013 Low levels are colder this run. 1000-850mb temps are finally responding to the evaporational cooling effects of the precip. Link to comment Share on other sites More sharing options...
Brick Tamland Posted November 25, 2013 Share Posted November 25, 2013 So that graphic I was talking about earlier from RAH that showed all rain for central NC was just for the onset of the event. They are talking about it possibly changing over to snow Wednesday night. Link to comment Share on other sites More sharing options...
FLweather Posted November 25, 2013 Share Posted November 25, 2013 ULL closed off this run(48) from 12z. First wave up north ULL developing in the South. Link to comment Share on other sites More sharing options...
burgertime Posted November 25, 2013 Share Posted November 25, 2013 Per the NAM congrats MS and AL. Both look to get some good snow though sfc. temps may cause a little havoc. Link to comment Share on other sites More sharing options...
burgertime Posted November 25, 2013 Share Posted November 25, 2013 @63 the mountains of NC just get hammered with that low. Probably a good 4-6. Link to comment Share on other sites More sharing options...

burgertime Posted November 25, 2013 Share Posted November 25, 2013 SV maps have 1-2 inches for CLT and points west to about HKY and it goes up to 3-6 as you go west of there. Link to comment Share on other sites More sharing options...

The Alchemist Posted November 25, 2013 Share Posted November 25, 2013 @63 the mountains of NC just get hammered with that low. Probably a good 4-6. Is that higher elevations, or is that run sending a little love down Saluda's way? edit... Thanks for the map guys. A little worried about that snow on glop of that ice...

calculus1 Posted November 25, 2013 Share Posted November 25, 2013 I see the typical lee side shadow extending up from the south towards Lenoir/Hickory on these snowfall maps from WxBell and InstantWeatherMaps. Link to comment Share on other sites More sharing options...
NCCatawba Posted November 25, 2013 Share Posted November 25, 2013 I see the typical lee side shadow extending up from the south towards Lenoir/Hickory on these snowfall maps from WxBell and InstantWeatherMaps. Yea I can even tell from the maps above. Reality probably shadows all the way up to Mount Airy. Link to comment Share on other sites More sharing options...

Don't know what's up with that. Precip map doesn't really reflect it. Link to comment Share on other sites More sharing options...
BullCityWx Posted November 25, 2013 Share Posted November 25, 2013 Don't know what's up with that. Precip map doesn't really reflect it. My guess is you're not able to grow dendrites because the RH is too shallow Link to comment Share on other sites More sharing options...
Blue_Ridge_Escarpment Posted November 25, 2013 Share Posted November 25, 2013 Don't know what's up with that. Precip map doesn't really reflect it. You're right, the precip map sure does not reflect this shadow. Possibly a warm nose which would make it sleet instead of snow? The only thing I can think of.

The only thing I can think of. You can get sleet from not having deep enough moisture in the column too, I believe. Also freezing rain/drizzle.

BIG FROSTY Posted November 25, 2013 Share Posted November 25, 2013 Yea I can even tell from the maps above. Reality probably shadows all the way up to Mount Airy. Please keep the shadow away from Mount Airy!!! I'm sick of 40 years of snow shadows. lol Link to comment Share on other sites More sharing options...
swva Posted November 25, 2013 Share Posted November 25, 2013 Probably overdone.. but like the trend for measurable snow with the ULL Wednesday afternoon/evening. Definitely a good run and we are close to the event. Models should be getting a clue. On to the GFS. Link to comment Share on other sites More sharing options...
wncsnow Posted November 25, 2013 Share Posted November 25, 2013 What usually causes that during ULL events is a combination of downsloping winds coming off the Blue Ridge, and a tendency for a nose of warm air to get trapped along the escarpment.

BullCityWx Posted November 25, 2013 Share Posted November 25, 2013 The NAM says places like Gastonia/Shelby/Hickory/Lincolnton miss a damaging ice storm by 1 degree. It's that close. Link to comment Share on other sites More sharing options...
calculus1 Posted November 25, 2013 Share Posted November 25, 2013 What usually causes that during ULL events is a combination of downsloping winds coming off the Blue Ridge, and a tendency for a nose of warm air to get trapped along the escarpment. We live in such an interesting micro-climate. The mountains will work in our favor early Tuesday morning to trap in the cold air; i.e., CAD. Then on Wednesday, the mountains will work against us as they trap in the warm air and don't allow the cold air to penetrate all levels of the atmosphere soon enough. It's quite intricate how this all works together. Link to comment Share on other sites More sharing options...
NCCatawba Posted November 25, 2013 Share Posted November 25, 2013 I think we are going to need a flash flood watch. Looks like 5.5" then cold air just blasts in. If you miss the ice pre-event you will likely see some post-event which could also warrant a Winter Weather Advisory. Link to comment Share on other sites More sharing options...

The only thing I can think of. maybe a little downslope affect? sounds odd i know, but the areas subject to downsloping are also the ones without much snow. and since the temps are sort of marginal anyway (when arent they in the se lol) it wouldnt take but a degree or so to throw a wrench into the snow potential also the infamous warm bubble could be there where the taller mtns to our left screw us by holding the cold air back just long enough for a royal kick in the butt edited to add: What usually causes that during ULL events is a combination of downsloping winds coming off the Blue Ridge, and a tendency for a nose of warm air to get trapped along the escarpment.

dsaur Posted November 25, 2013 Share Posted November 25, 2013 I'd like to see Goofy bringing that 0 line down into Ga like that. I can't remember if we like the Nam, or not, or only inside 12 hours, but I'm going to like it, because it's colder T Link to comment Share on other sites More sharing options...
