Lower single digits showing up for many NC lower elevation locations on the 0z NAM

A thing to note also is that actual temps have been several degrees colder than forecast. An example is here. The 0z NAM doesn't even show it getting at or below freezing here tonight, and yet we are already 32 and going for a low of 27. I think others also noticed that today with their temps.

Atlanta has a big 0 now on the latest run, but not a word from FFC.

They can't change the forecast with every run that comes out. They are playing it safe. As the day gets closer, the forecast temps will start to lower. Our NWS is doing the same here. We have a forecast high in the 40s yet the models don't show us getting above freezing for a high.

True.

One thing i learned while researching for winter forecasts several years ago, is that true arctic outbreaks can be modeled very poorly in the extended range due to the very shallow nature of the airmass. I think this is a classic case/example of that. In some ways it's similar to mis-modeled CAD situations. The models are much better than they were 10 years ago, but they still aren't perfect and these recent trends are an example of that.

 True, they've been slashing the highs/lows for Mon and Tue considerably from where it was earlier in the week. Looks like most of the local mets here and in addition to TWC is coming more in line with the models.

 

I know and no offense, but you live at about 50 feet above sea level near a huge swamp and are close to 300 miles SE of Atlanta  it is a different world climate wise here.  They are being ULTRA conservative especially when it is staring them flat in the face.  I currently have 19 at my house actually colder than last night at this time. 

To be fair, it's not like other local and national weather outlets haven't been doing the same. Heck most local mets didn't start adding single digit lows to their forecast until today. My guess is by tomorrow FFC will have done the same.

They are talking about it.  My forecast low here monday night is 6.  I am sure it will be closer to 0 though...

Cool graphic from FFC home page, but what's wrong with this chart? I mean, if it was 0 at KATL on 1/11/1982, can't you assume it was also 1 degree at some point on that date? Same thing with Columbus and 5 degrees. Just bugs me. Regardless, cool data for us cold weather lovers.

Their forecast temps are at least 10 degrees too warm.... :axe:

Does that kink in the isobars over N and S Carolina mean anything? Just looks funky ?

 

I am not positive mackerel but it looks to either be some interaction with the piece of energy that is already off shore or the development of a costal low even though the rest of run does not support a ton of development.  Hopefully someone with a little more knowledge then me can explain whats happening.

That's a cool graphic. i think the last true arctic shot i can remember was in jan 2003 following the super clipper. hickory had 10 inches of snow and we got down to 6 degrees on my thermometer that night.

You sure do have an obsession about their temps. Give it a rest. I'm tired of reading about it.

 

Anyway, 0z GFS still gets us below 0 up this way.. Haven't had temps like that in a long time.

Our local ch 4 met seems pretty adamant about snow in Greenville on Sun night. He said flurries or showers before ending and dusting to 1/2 inch N of 85 . I hope he's right, but frontal passage usually won't get it done here! He also had our lowest low of 11 Tuesday morning and the lowest high of 32 on Tuesday . He has a " snow meter " rating of 7 out of 10 for seeing snow here Sunday night

Well, I've got my wsw wind, but only .04 in precip when it's cold enough, lol.  That'll be black ice so I won't even get to see it unless I catch it falling :)  Goofy needs to find more precip. 

  And I guess the models will find a short wave to grow into something, and we'll be waiting for it as the cold erodes :)  Never easy here.   T
