January Mid/long Range Winter Discussion


Wow

Recommended Posts

I like where we at at this time by the maps Mark posted!  Plenty of time for changes, just hope the GFS switches into Euro camp!

 

I'll take 00z Euro, Looks like mostly snow or maybe mix! Close call but I'll take my chances this far out, and hope it holds and trends better....

No maps from the Euro? It seems we don't ever have play by plays and specifics on the model runs anymore.

 

On that run of the Euro, light snow breaks out in the Northern Mountains of NC at hour 132.  Then by 144 the northern mountains are getting obliterated while a streak of light to moderate snow about 30 miles south of the Virginia border extended about half way across the state from West to East. By 150 it's headed out of Northern Va.

This looks like a near miss for the Triangle in NC. A lot of agreement on models coming together on that miss too. Hard to see a southeast trend with retreating air mass in late week. Maybe more of a NW trend actually.

Yep that's the problem here, we hardly ever, really never see a SE trend.....  :axe:

 

06z GFS is a ugly cold rain storm..........

Bad runs last night. Even on the ensembles there seem to be many low locations too far inland. I agree they seem to want to Miller B this thing. I hate Miller Bs for us. Still early, but we'll see if today starts a trend. Just can't get any stinking cold air around with this moisture.

Seems like this system might come into agreement sooner than others due in fact that it might be an I95 system. However, will some members continuing to show a good winter system in NC, I assume model warfare will continue at will. 

Overall the High placement just needs adjusted :)

A good bit of variety in the 0z GEFS and GGEM members, a couple sig winter storms for NC in there.  The consensus though looks like a 95 special from DC to Boston.  The signal is growing stronger and pretty much all the global guidance has a storm, so this should be fun to track.

This time of year, there is always a chance, remote, but still a chance...

...and these are just a couple of panel shots brick, just a few ensemble panels.  Probably have some of these all the way up to Friday. Like was mentioned the consensus is a more northwest storm from our location, but we do have the luxury of time on this one.

looks like a pretty good snow storm right now for mtns. of wnc and western va.,,, hopefully this will trend a little more south and east with time and include more folks, maybe draw in some colder air.

GSP on the end of the week storm:

THE POSSIBILITY OF SEVERE WEATHER OR HEAVY RAIN
OVER THE PIEDMONT IS STARTING TO CREEP UP WHILE THE POSSIBILITY OF A
WINTER STORM DECLINES. IN SPITE OF OVERALL LOW CONFIDENCE...IT SEEMS
MORE LIKELY THAT MOST OF THE REGION WILL NOT HAVE ENOUGH COLD AIR AS
THE LOW MOVES PAST FOR ANYTHING OTHER RAIN ACROSS MOST OF THE
WESTERN CAROLINAS. THE EXCEPTION WILL BE ELEVATIONS ABOVE ABOUT 4K
FEET...WHERE THERE STILL REMAINS THE POSSIBILITY OF TEMP PROFILES
COLD ENOUGH TO SUPPORT SNOW...AND MAYBE LOTS OF IT.

The story of our winter next few days plenty cold but no storm, then Friday we have a good storm and not enough cold air,, go figure that one.   :axe::ee:

12Z GFS is not good at all, trough faster, weaker, no closed 500mb low. Only a few back side NW flow flurries and mountain snow showers. It even does not have the huge NE snow storm-just a moderate event. I hope the Euro is better.....

GEFS looks better.
