February 8-12 East Coast Storm Potential


REDMK6GLI

Recommended Posts

The upper levels didn't come together this run and yet there's still a decent QPF and coastal SLP signal. That's a really good sign. Odds are always against something big. But at least this time we have a chance for a big one. It wouldn't take much change to the northern stream to spin up a biggie on that 18z GFS prog.

Was hoping u would pop on. Glad you're getting ur snow tomrrw what I like about this is you are replacing a ridge position with a trough position and that argues for the best height falls

im going out on a limb here and saying the 0z gfs run will produce some eye candy or the 0z EURO.

We may or may not see eye candy runs over the next few days.  I just want to keep seeing a potent southern stream s/w and at least a northern stream that is basically favorable to phasing with an offshoot of the PV over central Canada and some ridging north of the Lakes.  That keeps the door open.

Thanks.  I'm not ready to celebrate until I actually see it dumping out.  I've seen things go horribly wrong in the short term too many times to feel completely comfortable.  But things are definitely looking good up here. 

 

And it's nice to have a mid-range threat to track at the same time.

Just brutal in here. As bad as accuwx forums. I'm gonna go enjoy tracking tomorrow's event from a last-minute perspective, but something needs to be done to keep :weenie: in check. It dreadfully hinders valuable analysis.

 

It's not that I'm being a weenie, it's just that I'm closely following any significant changes in the upper levels and determining if it can still produce or not. Obviously, the 18Z GFS is demonstrating that you can still get a Coastal storm with the setup for the storm itself being altered significantly. There are plenty of factors that can screw up the evolution of this storm, but this storm still has a fighting chance.

more than a fighting chance synoptically. by Thursday we may very well be looking at a blockbuster or not, but not a weenie statement and I firmly say that because the pattern looks awesome leading up to this looks very encouraging despite teleconnector support which we haven't really had this winter anyway

Which is fine—we're all keeping an eye on things as we move forward. Things like extrapolating two days out from hour 84 on the 18z NAM, or trying to pin down which guidance suite will start looking good, (forecasting the forecasts, no less!) are what cause misunderstandings and false expectations. Fundamentally, it's probably not even in our best interest to talk about "the storm"; the longwave trough could produce some kind of cyclone at some point over a several-day period, but that's about as concrete a prediction as can be made at this point.

Those doomsday runs on Sunday night did a number on our collective perception of this threat/time period.

we all know JB can make outlandish calls but if you have weatherbell premium he pretty much says what PB GFI says that the pattern leading up to the sunday/Monday system says BIG storm signal. very good explanation and dismissing this threat prematurely may be biting you in the ass. by the way paul I just got the Weatherbell premium today and it was WELL worth it

I deleted my post. Also, I was in Accuweather Forums for several years, so I know what your talking about. I can't be there anymore considering that I got kicked out almost two years ago. Anyway, I'll keep my eye on any other significant changes.

The euro ensemble mean suggests that the OP will come west on next run or two.

what we are seeing I believe is the tendency for the models to get loopy in the 4-6 day period. we've seen this LOTS of times with most of these threats only to see them come back in a big way. I am not worried whatsoever and think this storm looking at the pattern has a very good chance at coming to fruition. tonight may be a bit early but I expect to start coming back more amped with the storm

Why is there something wrong with extrapolating what may happen? As long as it is said as written fact it's no different than any other

Interpretation. You can argue a lot of things but the setup is there. Not set in stone but a lot of the ingredients, the important ones cannot be ignored.

You can also get annually for around $180

AS ALREADY WELL ADVERTISED...ANOTHER WINTRY WEATHER SYSTEM WILL

AFFECT THE AREA OVER THE WEEKEND. TODAY`S GFS AND EC MODELS DEPICT

TWO SEPARATE BATCHES OF ENERGY EMERGING FROM THE W/CENTRAL US TROUGH.

SINCE THE BATCHES OF ENERGY ARE SEPARATE...THIS KEEPS THE SYSTEM

FROM BECOMING A BLOCKBUSTER STORM (AS SOME OF YESTERDAYS MODEL RUNS

WERE HINTING AT). THE FIRST AREA OF LOW PRESSURE WILL MOVE SOUTH OF

THE AREA SATURDAY NGT BRINGING AN ACCUMULATING SNOW TO (MOSTLY)

THE SRN HALF OF THE CWA. A BREAK IN THE WEATHER ACTIONS IS

EXPECTED FOR SUNDAY, THEN A SECOND UPPER TROUGH/WEAK LOW PRESSURE

SYSTEM APPROACHES FOR SUNDAY NIGHT INTO EARLY MONDAY. THIS COULD

BE A RAINS/SNOW MIXTURE...ENDING AS SOME STEADY SNOW EARLY MON

MORNING. AREAS TO THE NORTH MAY HAVE MOSTLY SNOW...WHILE MOSTLY

RAIN OVER THE DELMARVA AND SRN NJ. AT THIS POINT...THERE IS STILL

ENOUGH UNCERTAINTY TO KEEP THE POPS/WX FOR THE WEEKEND ON THE

CONTINUITY `RAILS` AND KEEP HI CHC/LOW LIKELY POPS FROM SAT NIGHT

THRU EARLY MONDAY MORNING. IF THE TWO SYSTEMS DO AGAIN MERGE...THE

POSSIBILITY FOR A STRONGER STORM COULD STILL EVOLVE...SO WE ARE

STILL ADVISING PARTNERS TO BE PREPARED FOR ACCUMULATING SNOW THIS

WEEKEND. WORDING IN THE HWO FOR THE AFTERNOON WILL CARRY ON AS

BEFORE.

JB is spot on with his pattern recognition and sounds very confident as do you and explained the GFS/ECMWF tendency to misinterpret outcomes of storms in this time frame. this should really quell some concerns that some have in here of this storm maybe not happening to its fullest potential

The ensemble track looks something like the early January storm with lower ratios

since the airmass wont be as cold.

 

attachicon.gif14010300.gif

no certainly wont be as cold, but CBS2 new York just said if this storm did hit it was going to be a lot of rain/snow at the coast, If it does hit with full force it probably wont be rain/snow :axe:

think I just may stay up for the 0z suite of the GFS tonight :popcorn:

You are 5 days out. Use the ensembles here. An OP run may look nice and then it's Gone at 6z. Once inside 72 hours u look close. Get thru tomorrow. Its is a major ice storm for some.

The entire metro area is now aware of this threat' people are talking about it who haven't any clue, about the weekend superstorm as my kids teachers called it. translation; any snow at all from this system will be hyped beyond all reason, even a 3-6 incher.

Like you said i am using ensembles and the 18z ensembles were a real improvement saying to me that there seems to be more amped solutions over OTS solutions paul. Im expecting to start seeing some correction in the orientation of this storm starting tommorow. Think we're starting to get past the blip that was the first wave on saturday, as you aluded to pattern argues for one LP
