Noone wants to hitch their forecasting wagon to the GFS, but it's by far been the most consistent with the shortwave track and strength. The euro shifted the energy nearly 300 miles south today and looks nothing like it's own ensembles.

 

That being said, it's still the Euro...

 

Right so when the GFS is all consistent and acts like the Euro its wrong but when the Euro jumps all over the place run to run like the GFS its right....go figure

This will be a non event for NC, I love snow as much as anyone else but this precip will be supressed and it will be on to the next one. Hopefully February will be good to us. I know that we have had way more rain, precip, moisture since fall than has been forecasted. I think we all have been reminded of that atleast 50 times a day. I just feel the timing is way off based on the better models. I am looking forward to spring and getting away from the let down!

Spring will come that is guaranteed. However we hunt the elusive snow as it is not ever guaranteed rounds these parts.

I totally agree with you on that! I was hopefull as most but it just isn't gonna be this time. I hope we have something in the very near future. I would rather settle this with myself than get my hopes up on every decent model run.

Heard Carl Parker of TWC fame , use one of our winter catch phrases this afternoon! He showed the shortwave for our Sun system , and he said

" it was in a data sparse location in the Pacific"

Yeah I flipped TWC on out of curiosity around 4, it wasn't Carl Parker but Alex Wilson had the 5 day forecast going and I saw based on their map for Sunday they clearly weren't going with the GFS. At this point I think as a media outlet you have to go the safe route and say it's possible but lean Euro

absolutely, still time to honk the horn if the euro were to come around.  but if the gfs loses the storm tonight or tomorrow it is much easier to not have to backpedal.

That's what I don't like about the Euro. It seems to just be throwing darts all over the place in hope of just hitting something. GFS might be wrong but it is more consistent. The Euro is like the guy that either strikes out or hit home runs every time at bat.

Plenty of time left when you have two of the top models on either side of a coin, you're going to have some uncertainty...so to say that this goose is cooked, or the fat lady has sung, or that the euro will win the coup, or whatever the sayings are is premature. I believe the low precip concerns are valid, however there may be a decent amount of convective feedback with the GFS, you never know where the moisture will trend this far out when the track itself is this variable. Often times we can see storms trend wetter as we get closer well inside 80 hours, especially with the mesoscale models.

 

IMO Euro will cave to GFS.

 

Edit: Accidentally deleted my post (I've had a long day) but it was basically this:

 

The Euro Op runs today aren't agreeing with their ensembles in regards to the 500mb pattern and/or s/w location, however you want to view it.

 

The GFS and GEFS, however, agree. Take the 12z runs today for instance. The GFS s/w matches up quite flawlessly with the 500mb anomaly over Texas.

 

12z GEFS (ensemble)

12z GFS (op)

Now look at the 12z EPS (ensemble)

and the 12z Euro (op)

1RSbZmx.png

 

See how the s/w is in mexico on the OP but over texas in the Ensemble? Now compare 500mb maps on both the 12z EPS and 12z GEFS, not too far apart. The reason the Euro is staying supressed is not because of overwhelming cold or because it's the crystal ball of weather, but because the s/w is staying positive too long and just keeps on going with no digging whatsoever. Because of these inconsistencies (which are replicated on early runs as well, such as the 00z suite), I prefer the GFS as of now. We should see big changes in the Euro soon, as it will take a lot to change the GFS now that it (and it's ensembles) have really nailed down a general look, IMO.

Phew. Second time I've typed and uploaded those images, goodnight!

Rates will over come all.

 

Agree the sounding look cold real close to the ground for a lot of us, this isnt some huge warm layer we have overcome its really shallow and its not going to be a big problem, it might start with some rain/drizzle to start but as soon as rates get anywhere near decent the snow makes it to the ground and surface temps should get on down to 32 easily. Also lets hope the typical GFS warm bias is in play, that will shave 2-3 degrees off as well.

In areas where the 540 line is overhead, I would have my doubts. But if you're sitting in the mid/upper 30s and have 534s or better, I wouldn't worry until game time.

RNK will bet on the  Euro: 

 

.SATURDAY AND SATURDAY NIGHT...MOSTLY CLOUDY. HIGHS IN THE UPPER
40S. LOWS IN THE LOWER 30S.
.SUNDAY...MOSTLY CLOUDY IN THE MORNING...THEN BECOMING PARTLY
SUNNY. COOLER WITH HIGHS IN THE UPPER 30S.

.SUNDAY NIGHT THROUGH TUESDAY...PARTLY CLOUDY. LOWS 15 TO 20.
HIGHS IN THE MID 30S. WIND CHILL VALUES AS LOW AS 5 ABOVE.

From KCAE 6pm or so: (i think they are basically saying they will watch it for the northern most midlands, not the central midlands btw)

 

 

 

THERE REMAINS SOME  
DISCREPANCY AMONG THE GFS/ECMWF REGARDING THIS SECOND SYSTEM WITH  
THE ECMWF BEING MUCH FURTHER SOUTH WITH LESS MOISTURE AVAILABLE  
COMPARED TO THE GFS SO UNCERTAINTY IS HIGH AND THEREFORE  
CONFIDENCE IS LOWER THAN NORMAL. WILL CONTINUE WITH THE SLIGHT  
CHANCE POPS WE CURRENTLY ARE FORECASTING UNTIL A BETTER  
CONVERGENCE OF SOLUTIONS OCCURS. THE FORECAST SOUNDINGS DO NOT  
SUPPORT ANY PRECIP TYPE OTHER THAN RAIN ACROSS THE FORECAST AREA  
ALTHOUGH LATEST GFS BUFKIT TIME SECTION FOR CLT SHOWING SOME LIGHT  
SNOW ACCUMULATIONS FOR LATE SATURDAY NIGHT/EARLY SUNDAY MORNING.  
GIVEN CURRENT UNCERTAINTIES...WILL KEEP PRECIPITATION IN THE  
LIQUID FORM FOR THE ENTIRE FORECAST AREA.

Big Frosty just wondering what J B is saying about this storm?
