Yea.. the 6z gfs is essentially 1/12/11.. tracks over the cape giving everyone feet with dynamic cooling.. I'd rather have a little taint of rain tho than a boring whiff.. tracks west don't both me yet.. it can always come back east a little...

The Nam showing nothing does kind of scare me

Nam does not scare me at all, It has done this just about all winter being late to the party, It will come around at some point, Probably as soon as today if not by 12z tomorow

The only bad thing about this run is it can only get worse from here on out. This is about as good as it gets in every single aspect from mid-levels to upper levels to sfc for SNE...esp eastern half of SNE. The only limiting factor is the April sun angle...but it pretty much will not get better than this in any model run from here on out. This is a KU for SNE in April....so do not get married to this solution.

Married? That's crazy talk. But I'm sure you don't mind if I spend 15 minutes in the bathroom with it, do you?

What is keeping the ens means se Scooter, lack of amplification due to too many S/w's in the flow?

They seem to be perhaps weaker with the middle shortwave, but ensembles sometimes do this as the resolution perhaps isn't enough to truly depict the s/w intensity. I made a comment about the models coming to a compromise, but perhaps the op runs turn out to me more correct? Very dynamic time of year. HPC seemed to take a compromise of the GEFS and euro op, with a bit more weight to the op.

Thanks Scooter, I really appreciate your thoughts.........should be a fun couple days, and by tonight only 48 hours from potential start time down here, its really not that far off at all!

BOX has been reading Blizz's posts:

MAIN POINTS

* HIGH PRES WITH COOLER AND DRIER AIR WILL HOLD THRU THURSDAY

* COASTAL STORM...PSBL NOR`EASTER...THURS NGT EXITING BY SAT MORN

* RIDGE OF HIGH PRES SATURDAY INTO MONDAY

* ANOTHER SYSTEM EXPECTED FOR THE BEGINNING OF NEXT WEEK

OVERVIEW...

INITIALLY 0Z GFS REMAINED A STRONG OUTLIER WITH REGARDS TO THE

COASTAL STORM EXPECTED BY THE END OF THE WEEK...BUT NOW THE LATEST 0Z

ECMWF HAS DEVELOPED A VERY SIMILAR STRONG SOLUTION...AND MUCH CLOSER

TO THE NEW ENGLAND SHORELINE. CONSIDERED THE 12Z ECMWF/18Z GFS WITH

THE LATEST FCST PACKAGE...BUT NOW FEEL A STRONGER OUTCOME IS QUITE

POSSIBLE FOR OUR NEXT STORM. UNCERTAINTY STILL ABOUNDS...NAO/AO

TELECONNECTIONS ARE FCST TO A NEUTRAL STATE BY THE TIME THE COASTAL

STORM TAKES SHAPE LENDING TO A WEAKENED BLOCKING PATTERN AND LESS

COLDER AIR ENTRENCHING INTO THE STORM. CHALLENGES WILL CONTINUE IN

REGARDS TO BOTH SFC TEMPS AND WINDS PRIOR...DURING...AND AFTER THE

STORM. DETAILS WILL LIKELY CHANGE.

DETAILS...

WEDNESDAY NIGHT INTO THURSDAY...

ARCTIC RIDGE OF HIGH PRES BRINGING SEASONABLY COOL WEATHER TO THE

RGN WILL RETAIN A STRONGHOLD ACROSS THE AREA. MID-LVLS WILL REMAIN

BELOW FRZG AND EXCEPTIONALLY DRY. CLOUDS WILL LIKELY BE ON THE

INCREASE FROM THE SW AS A WEAK DISTURBANCE THRU THE LONGWAVE PATTERN

TRANSLATES EWD THRU THE MID-ATLANTIC/SERN CONUS RGN. WILL RETAIN

SLGT CHC POPS FOR THE EXTREME S/SW PORTIONS OF NEW ENGLAND FOR LIGHT

RAIN/SNOW UNDER LIGHT AND VARIABLE SFC WINDS.

COASTAL STORM (THURSDAY NIGHT THRU SATURDAY)...

A SERIES OF SHORTWAVE DISTURBANCES WILL ROUND THE BASE OF A H5

LONGWAVE TROF FRIDAY RESULTING IN THE TROF AMPLIFYING AND BECOMING

POSITIVELY TILTED...POSSIBLY A CLOSED LOW...THRU THE NERN CONUS INTO

SATURDAY. DISTURBANCES DO NOT APPEAR TO PHASE...AND THE STRENGTH/

AMPLIFICATION OF WHICH DIFFER AMONGST MDL SOLUTIONS RESULTING IN

VARYING OUTCOMES OF UPR LVL DYNAMICS...ENHANCED LIFT...AND SFC LOW

DEVELOPMENT/PLACEMENT. RATHER THAN GOING INTO A DEEPER DISCUSSION

CONCERNING ALL THE VARIATION AND UNCERTAINTY...THERE ARE SOME MAIN

HAZARDS THAT WILL REQUIRE ATTENTION.

ONSHORE WINDS...THE LOCATION/STRENGTH/TRACK OF THE SFC LOW WILL

LIKELY DICTATE SFC WINDS. A STRONG NE H925 LLJ UPWARDS OF 50KTS IS

APPARENT BY MIDDAY FRIDAY PER LATEST 0Z ECMWF. WIND...ALONG WITH A

DEEPENING LOW...WILL HAVE IMPLICATIONS TO SHORELINE COMMUNITIES

CONCERNING SURGE POTENTIAL. UNCERTAIN AT THIS TIME IF WINDS WILL

EXCEED WIND ADVISORY CRITERIA OVER LAND.

SNOW POTENTIAL...SIMILAR FACTORS CONCERNING THE AREA OF LOW

PRESSURE WILL IMPACT TEMPERATURE FIELDS. BOTH GFS/ECMWF HIGHLIGHT

SFC WET BULB TEMPS BELOW FRZG FOR INTERIOR PORTIONS OF CT/MA/NH IN

ADDITION TO SFC TEMPS BELOW FRZG FOR HIGHER ELEVATIONS. LITTLE

CERTAINTY PRESENTLY ON DIURNAL TRENDS AND PRECIP TYPE...WILL HAVE

A BETTER HANDLE AS WE GET CLOSER IN TIME. AS BOTH GFS/ECMWF

PRESENT DIFFERENT SOLUTIONS CONCERNING LOW PRES DEVELOPMENT...MID-

LVL FIELDS DIFFER WHICH IMPACT PRECIP OUTCOMES. ACCUMS ARE

UNCERTAIN AT THIS TIME.

And they mention another storm next week? But a warm front...

Problem is the NAM handed it to the GFS with that last storm that pretty much whiffed. GFS literally got owned during that storm as it was advertising warning criteria snow to the NH/MA border only 24 hours out... which ended up being 1-2" across far, far SNE.

And if I am remembering things correctly, when NAM does show the storm it will soon show twice the qpf of all the others and probably end up with the others chasing towards it at the end.

It does appear that some snow is en route. It will be interesting to see what wins out: the melting of the remainder of my field or a replenishment of undetermined depth.

I don't think a snow storm will sit well with my daughter's visit to Keene. She was there in the snow a month or so ago. I think she might find sitting in the stands watching Jay play at Towson a better climatological place.

Meanwhile, looks like a relatively warm one today. Already up to 30.1/14.

EC and 06z GFS ensembles are pretty far se, actually. However, eventually we have to start to move way from ensembles and start weighing in the op runs. EC ensembles are just about near or a hair se of the BM. That could be a good thing because perhaps we see some sort of a compromise, which could be good for a lot of us, but yes caution is to be observed since we have many more runs to come.

:weenie:

I won't go out and say that its totally wrong here it would be a major coup if it trumped all the other guidance including the GFS, But thats the problem, The GFS lies within all the other guidance outside of the NAM, Right now, The Nam is the outlier as it lies the furthest east for the most part..

This run destroys the areas from NJ (esp higher elevations) up through western mass. Perfect 700mb track for them. It also has a secondary QPF max area..perhaps CF or very strong low level frontogenesis related, over ern and se areas.

I get a foot of snow on the 6z gfs here in coastal NJ lol..Zone omega is even crazier. It really is perfect, and fun to look at

Quick word of caution -

No model yet benefits from the denser sounding domain over land. The bulk...all actually, of the jet dynamics are over the NE Pacific as of 06z. One could argue that the 12z initializaiton this morning might get tickled, but really that is 00z onward tonight. As tempting as it may be to bite into a 06z GFS solution, there could be some significant adjustments by 12z Wednesday morning, despite the fact that we are only really 84-96 hours from whatever is going to unfold from this.

Or not - often enough however we do see system mophology upon final relay over land.
