February 8-12 model Discussion II

Recommended Posts

The GFS continues to look horrible, if you want wintry wx. Does anyone have anything on the Ukie, GGEM, etc.? Curious to see how these other models are lining up with the GFS? Ugh...I am hoping for one more good shot at wintry wx before the warmup. Either way, I am not cliff diving, unless this scenario (0Z GFS) is still showing up on Tuesday. What an awesome Super Bowl huh? :thumbsup:

Nothing yet on the UKMet. GGEM is out to hr12

wierd to see the other models trend towards the GFS and not the other way around. All these twists and turns sure make it fun to see unfold though. Sure would be boring if we knew 3-5 days out already what was gonna happen. Half the fun is just watching the models come up with a solution. whether we win or lose it sure has been a fun winter to watch!

It would be a rare win for the GFS- just do not like it trending the wrong direction. Not giving up yet- but getting more worried certainly. If the Euro and CMC are drier, that may be the ball game.

However, if the king doesn't abdicate with its solid 2-3" for ATL, ATL will remain very much in the ballgame in my mind.

I called this 2 days ago when the models were actually saying everyone was in good shape for a good storm. There just isn't anything to even make this storm grow, it just dies along with winter. Who would have thought Jan 10th might have been the last accum snow in NC? I sure didn't but that's certainly how it's looking.

I guess I'll take some sprinkles/flurries

I seriously doubt you'll get Sprinkles Thursday morning.

HPC is discounting the 00z GFS as the big outlier. :thumbsup:

HPC:

PRELIMINARY PREFERENCE... 00Z NAM/12Z ECMWFS

THE 00Z NAM AND 12Z ECMWF/CANADIAN ARE SHARPER ALOFT AS THE

SHORTWAVE DROPS THROUGH THE FOUR CORNERS REGION LATE TUESDAY

COMPARED TO THE 00Z GFS AND 12Z UKMET. BY 00Z/10... THE 00Z NAM

AND 12Z UKMET BECOME QUICKER WITH THE SFC LOW NEAR LOUISIANA

COMPARED TO THE 12Z ECMWF/CANADIAN. THE 00Z GFS SHEARS THE VORT

MAX OUT RATHER QUICKLY COMPARED TO ALL OTHER GUIDANCE. ENSEMBLE

LOW CLUSTERING WOULD FAVOR THE 00Z NAM AND 12Z ECMWF SOLUTIONS AND

WILL STICK WITH THAT AT THIS TIME THOUGH MODEL CONSISTENCY HAS

BEEN POOR WITH THIS SHORTWAVE OVER THE PAST SEVERAL DAYS.

Who knew that winter doesn't end until March 21st? I sure did.

By the way, this is my first post!

LOL. Snow can fall in the South as late as April. It has happened before, and it could happen again. Winter is far from over, Imo.

Sure it can, but with the days rapidly lengthening and sun angle getting increasingly higher each day, it makes it harder to get a good accumulating snow especially if it falls during the middle of the day. I've seen it snow heavily for hours in late Feb and March during the middle of the day and have very hard time sticking.

The UKMET is far south with its surface low. The RH is just south of TN and NC, so the Dixie states get snow, and the 0 line is well south of I-20.

That's a healthy RH field on the UKMet. Looks good for BHM-ATL. Give it the normal NW trend the next few days and others get in the game. GGEM was a disaster though.

Yeah, but this is the year, the golden year, when against climo and history, the Atlanta area got a snow storm on Christmas day. Anything is possible this year. I'm expecting the return of the March triple phaser, and maybe some flurries in June to top things off, lol. T

The heaviest and deepest snow I've ever been in occurred in Floyd County, VA the last week of April. Over 30 inches in 12 hours complete with thunder, exploding transformers and falling trees. The snow fell from 8am til 8pm and had no trouble at all covering wet ground and even large puddles in a very short time.

Yep. The 850 mb 0C line is all the way down to CSG-MCN-south of Aug-south of CAE. IF there were to be some solid precip. generated after hour 72 (big if but quite possible since its 700 mb 90+% RH area is much more impressive than 0Z gfs and ukie has closed sfc low in Miller A position vs. none on 0Z gfs), which we'll never know for sure since qpf cuts off at hour 72 on Ukie, we could very well be looking at a very nice and rare several inch snowstorm through much of Central GA/SC! Stay tuned, folks!

Very much agreed. Got to remember those 3 and 5 day model verification numbers....Euro #1, UKMet #2

Agreed, but the fact that the CMC has now joined the "what storm?"parade, I have that sick feeling in my tummy. New GFS ensembles are wetter than the Op which is good,but they are drier than previous runs. My feeling is we have two scenarios: a total bust with flurries/nothing-or maybe a 1-2" storm. The chance of more than that is getting less with each passing run. Even if the Euro has precip, if it is less than the 12Z run, that is another small step in the wrong direction. Hope is hanging by a increasingly more slender thread.

No question that the storm vanishing scenario is on the table too if we can't get any amp in the wave. I still like the good cold look though. I'd rather take my chances around here with the precip rather than the cold air.
