January Pattern Discussion

Need the confluence further south, or just less of a northern stream or whatever we say every time a model shows a Miller B too far north.  And although the area has been screwed by Miller Bs they've also been some of our biggest storms, so I can't say I hate them.

Just checked the D+8 superens analogs centered on the 5th which would include the 3rd.  Nothing scientific about it but the analogs really liked snow.  6 of 10 had snow within the window.  Four of the six where in the 3-5 inch range,  the others were lighter.  The top analog was dec 24, 1962 the second ranked was Dec 29, 1967.  We still don't know much except there is potential for some snow but we still have a good chance of getting a miller b evolution which can sometimes produce if the low redevelops far enough south. 

Well this is at least a positive sign.  I can't remember when we had that many favorable snowy analogs.

I know how much wes loves when the 850 runs well north of us.

I don't like seeing the 850 low to the north but if the sfc  low develops quick enough off the NC coast, a new 850 low may form.   The euro ensemble have the low off the coast at 132 hrs. I think it's a better look than the operational though that could be wishful thinking.

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...

SHORTWAVE DEPARTS TO THE EAST TUESDAY MORNING. WEAK RIDGING AT THE

SURFACE AND ALOFT MOVES ACROSS TUESDAY INTO TUESDAY NIGHT AS COLD

HIGH PRESSURE BUILDS TO THE NORTH.

MAIN FOCUS IN THE LONG TERM CONTINUES TO BE POTENTIAL FOR LOW

PRESSURE SOME TIME BETWEEN LATE WEDNESDAY AND FRIDAY. MODELS ARE IN

SOMEWHAT BETTER AGREEMENT THAN AT THIS TIME YESTERDAY AS MOST

NOW DEPICT A DIGGING TROUGH. BUT THE TIMING AND STRENGTH OF THE

TROUGH STILL DIFFER GREATLY FROM MODEL TO MODEL AND RUN TO RUN.

GENERALLY STUCK TO WPC GUIDANCE...BUT POTENTIAL EXISTS FOR SOME

WINTRY PRECIP WITH AMPLE ARCTIC AIR NEARBY.

DT is flopping around like a river trout right now.  His acolytes' heads are exploding.  DT will be so busy tracking MammaBear72's route home from BFE Tennessee to BFE West Virginia that he may not have time to make a forecast.

I love reading the comments on his FB.

 

Speaking of DT and his forecasts, nobody has mentioned the storm on the 31st he forecasts for Mid/Southern VA.

Eh if it's sporadic and useful cutting and pasting is a big part of the board.

I agree.  Each thread tells a story.  Having all the info on a period of time consolidated into a thread can be quite useful even national NWS forecast outlooks.  That cut and paste sure beats the hell outta "The GFS looks great" or "Looks like the Euro caved".  At least there is some substance to the cut and paste.

I don't know what to make of his posts. "12z Euro bad for Va snow lovers" is sandwiched between "life threatening cold" and "12z Euro brings low south giving widespread snow to va and all of Maryland".

Was wondering same thing. Could he have meant "12z Euro Ensembles"?

He posted Jis' favorite, the control run of the euro ensembles and acted like it was a new forecast when it's just a lower resolution forecast than the operational.  I ended up posting on his site that he needed to make that clear.  The euro ensemble mean is more in line with the control than the operational which makes you wonder a little about the more suppressed look to the ensemble mean  may be partly due to the resolution.

Heck, I do it all the time. It's easier to explain thoughts with pictures but I'm also one who doesn't mind looking at the various discussion as I normally won't go looking for them.

Yeah same. There is overkill at times but also some value. Hopefully most who do it are looking for that kind of value. The worst is pasting a live/time sensitive image in a model thread or something.. Going back to look at a snowstorm in July shows us all excited about a mega ridge. ;)

hmm idk, it confused me as well, I haven't see the euro ensembles to know if he meant that. I hope he meant that cause if not one statement contradicts another lol

Looky here a copy paste job!! This is a portion of the Mount Holly AFD concerning the late week event. I found it somewhat amusing and interesting to see their thoughts on the key features and how the current model guidance is handling it, and possible outcomes going forward.

 

ANOTHER DAY CLOSER, BUT NOT MUCH CONSENSUS YET WITH THE NEXT

SYSTEM. WE HAVE SEEN A MYRIAD OF SOLUTIONS OVER THE LAST FOUR
SOUNDING RUNS. IF THE ONLY CONSISTENCY OF DETAILS HAS BEEN THE
INCONSISTENCY, THEN THE ONLY CONSENSUS AT ALL IS THAT OUR CWA WILL
BE AFFECTED. COLD, DRY AIR WILL OBVIOUSLY BE IN PLACE. THE TWO
IMPORTANT PLAYERS: THE SOUTHERN STREAM ENERGY, HOW LONG WILL IT
DAWDLE. THE 12Z ECMWF WAS FASTER EJECTING IT THAN LAST NIGHT, BUT
STILL SLOW OVERALL. ANYTIME THE ECMWF HANGS IT BACK MORE THAN ANY
OTHER MODEL, ITS NOT A CONFIDENT FEELING. THE SECOND PLAYER IS THE
ENERGY ENTERING BRITISH COLUMBIA AROUND 12Z ON NEW YEARS EVE. THIS
PIECE OF ENERGY DIGS THE TROF. HERE WE STILL HAVE THE UKMET AND
CAN GGEM DIGGING THE TROF FARTHER TO THE WEST, THE ECMWF TRENDING
WEST AND THE GFS THE LATEST TO DIG IT FARTHER EAST. THE OUTCOME
GIVES A PLETHORA OF MODELING SOLUTIONS FROM MORE RAIN THAN SNOW
FOR THE CAN GGEM, TO THE MILLER B SOMEONE WILL GET THE SNOW SHAFT
ECMWF TO THE MOSTLY SNOW BUT WEAK GFS. WITH THE GFS ENSEMBLE MEAN
FLATTER THAN THE OP GFS (ALTHOUGH TWO MEMBERS ARE ON THE RAINY
SIDE), NAEFS HARDLY BUDGED FROM 00Z. THIS IS THE FIRST TIME THAT
THE OP ECMWF IS FARTHER NW THAN ITS PRESENT ENSEMBLE MEAN WITH
THIS SYSTEM. THE ECMWF ENSEMBLE MEAN IS PRETTY CLOSE TO THE OP JMA
SOLUTION. THE THOUGHT PROCESS WITH THIS PACKAGE IS TO LEAN TOWARD THE
BETTER CONSENSUS DIGGIER SOLUTIONS, THE ONLY SOLUTION WE ARE
TAKING OFF THE TABLE IS NOTHING WILL HAPPEN.

He posted the control run of the ensemble suite like it was the euro.  It's a lower res version with the same initial conditions as the operational.   He may have meant to post the ens mean which is farther south and more in line with what he was saying but that is not what he said or posted.

Plus it was from the 0z ctrl run, not the 12z ctrl run, couldn't tell if we wanted to say with that post.
