Iceagewhereartthou Posted February 18, 2020 Share Posted February 18, 2020 8 minutes ago, DopplerWx said: when is the last time you saw the nam overdo a warm nose only to have it trend colder as we got closer to verification? the warm nose will likely be stronger than advertised. believe these 8-10" outputs at your own peril. In past years the NAM had a tendency to underestimate the warm nose resulting in much of it's snow being sleet, especially on the SW fringes. Dec 18 is a perfect example. It has done very well this year and with it pulling the frozen precipitation line north that is not a good sign for areas south. Certainly could come back south over the next 48 hours though. Profile readings not matching it's precip output though. Profile suggests snow much further South, but output removes virtually all snow from SC.

Caution on using one temperature layer for warm noses, they can pop up anywhere from 900-700mb I mean, I’ve had sleet at 20 degrees not because there was a warm layer but because the dang moisture was too shallow. If it can find it, it usually does! Link to comment Share on other sites More sharing options...

Totally. Is it likely as modeled? I don’t think so. I generally agree for your area. But I thought the same thing 24-36 hrs ago for my own. I confidently thought that the only limiting factor in my area would be moisture because I was solidly entrenched within the upper level cold on all the models. 1 Link to comment Share on other sites More sharing options...
olafminesaw Posted February 18, 2020 Share Posted February 18, 2020 The ICON takes a step in the wrong direction. Looks pretty anemic. I've never really found it to be a reliable model though. 1 Link to comment Share on other sites More sharing options...

SnowDawg Posted February 18, 2020 Share Posted February 18, 2020 Just looking there on weather nerds the warm nose looks most substantial from 750 to 800 mbars and isn't really showing up much at 850. So that's why we can't see it on temp maps on most sites. 1 Link to comment Share on other sites More sharing options...

Or a bit further West in the true foothills... I don't think it would be as much of an issue in Winston and GSO. 1 Link to comment Share on other sites More sharing options...

If we get a dusting that is a win this year though. I will be the first to admit that I have been adversely critical of your statements on this winter! Nothing personal I promise! I guess it was due to your statements of no winter. The pattern sucks and I get that! Warm and rain and a day or two of cool and dry! I would appreciate your honest thoughts on this system/setup later after the models have hashed out the best they can! Link to comment Share on other sites More sharing options...

Anywho, thur going to suck around here...thinking much of north ga/upstate will end up with it being 33 to 35 because of how cold the low levels will be.

PackGrad05 Posted February 18, 2020 Share Posted February 18, 2020 Regardless of what happens, the overnight hours on Thursday and early morning hours of Friday will be messy and nasty. Especially with temps dropping into the 20s as soon as the system departs. 1 Link to comment Share on other sites More sharing options...
FlatLander48 Posted February 18, 2020 Share Posted February 18, 2020 GFS at Hour 42, I believe that the trajectory looks the tiniest bit more of a SW/NW flow, believe it will come north a tad, though nothings stands out really compared to the 6z.

Hour 48, 50-75 mile push north compared to 6z. Also showing a tendency at the same time frame over the last couple of runs (still at 48) of the storm appearing stronger each run. at least in terms of precip rates. 2 Link to comment Share on other sites More sharing options...
PackGrad05 Posted February 18, 2020 Share Posted February 18, 2020 Greg Fishel from his Facebookl: "...... In my estimation, the upper level pattern is wrong, the surface high is in the wrong place, and most if not all of the precipitation will fall while temperatures are above freezing. For snow lovers, I do not believe this upcoming late week weather event is going to be your meteorological messiah. Might we see a few flakes? Yes, but every time I venture outside you've got that so what's the big deal??? More to come later today." 1 Link to comment Share on other sites More sharing options...

StantonParkHoya Posted February 18, 2020 Share Posted February 18, 2020 As has been discussed ad nauseam, the high is in the historical exact place for NC snowstorms.
