Euro is east but looks to have 2 lows like the GGEM. Still early to say where the track will be. Nice run.

 

 

Well right now I rather have it a bit East than too far west as it usually will track west anyway in most cases so better for wiggle room as we get closer. If it starts moving any more South/East next couple days than I will lose hope.

We missed the two March snows to our south already, along with the Regulus star blackout yesterday morning due to clouds.  We should have an OTS blizzard for the last blow this month.  :baby:  :(  :weep:  :cry:  At least the mega cold pattern appears to end in 6 -7 days, and replaced with 50's for highs more consistently. :sun:

:baby::weep::cry::axe:  emoticons can say a 1000 words....

I wouldn't get too worked up over it yet, there are still some very heavy hitters on the individual Euro Ens members and the mean is still a nice event 6" plus for NYC Metro, so it's pins and needles for the next couple runs....

This month feels like the movie groundhogs day...

Lol, yes indeed. We need to see the front running piece of vorticity that is on the the big 3 to wash out or slow down and jump in the deep trough for this one to deliver the goods. Very tempered expectations at this point...

...NOR'EASTER BOMB INDICATED OFF THE MID-ATLANTIC COAST LATE
TUESDAY NIGHT...


WITH THE REESTABLISHMENT OF CROSS-POLAR FLOW INTO NORTH AMERICA
DURING THE NEXT FEW DAYS, BAROCLINICITY WILL MARKEDLY INCREASE.
THE LATE-MARCH SUN CONTINUES TO WARM AREAS SOUTH OF THE POLAR
FRONT, WITH THE INFUSION OF NEARLY UNMODIFIED ARCTIC AIR INTO THE
NORTHERN TIER OF STATES. THIS THERMAL CONTRAST IS, OF COURSE, PART
AND PARCEL OF THE JET STREAM, WHICH IN TURN PROVIDES THE
BACKGROUND ENERGY FOR THE PERTURBATIONS WENDING THROUGH THE FLOW.
SOME OF THE DEEPEST EXTRATROPICAL CYCLONES IN MODERN
RECORD-KEEPING HAVE AFFECTED THE CONTIGUOUS UNITED STATES DURING
THE MONTH OF MARCH--THEIR GENESIS AFFORDED BY THE MONTH'S NATURAL
BAROCLINIC INSTABILITY.

ONCE SUCH PERTURBATION IS PROGGED TO GROW VIGOROUSLY AS IT LIFTS
UP THE SOUTHEAST COAST TUESDAY MORNING, THEN BOMB OFF THE
MID-ATLANTIC COAST TUESDAY NIGHT WHEN THE JET STRENGTHENS VIA AN
INJECTION OF ARCTIC AIR FROM THE MIDWEST. MANY MODELS--INCLUDING
THE 00Z/21 GFS--DEEPEN THE OCEAN STORM BELOW 970MB NEAR THE
ATLANTIC BENCHMARK OF 40N/70W WEDNESDAY MORNING. FOR THIS
PARTICULAR SET OF MANUAL PROGS, RELIED ON THE MOST RECENT ECENS
MEAN FOR A BEARING, SINCE NOT ALL THE GUIDANCE WAS YET ON THE SAME
PAGE WITH THE PARTICULARS OF THE CYCLONE. THE ECENS MEAN HAS SHOWN
HIGH SKILL AT THE MEDIUM RANGE WITH SURFACE PRESSURES, AND SEEMS
TO OFTEN ARRIVE AT A STABLE SOLUTION A DAY OR SO SOONER THAN MUCH
OF THE OTHER GLOBAL NUMERICAL GUIDANCE.

THE EAST-COAST CYCLONE HAS THE POTENTIAL TO PRODUCE LATE-SEASON
HEAVY SNOWFALL OVER A WIDE SWATH OF REAL ESTATE FROM VIRGINIA TO
NEW ENGLAND; THAT IS A GENERALITY AT THIS POINT. MUCH REMAINS IN
TERMS OF REFINING THE FORECAST STATE BY STATE. ANOTHER HIGH-IMPACT
FACTOR WILL BE THE POWERFUL WINDS GENERATED BY THIS SPRAWLING,
INTENSE CIRCULATION, ALONG WITH HIGH SEAS, BEACH BATTERY, COASTAL
FLOODING, AND SO FORTH. AGAIN, AT THIS POINT, SUCH SENSIBLE
WEATHER EFFECTS ARE SIMPLY ATTENDANT TO THE POTENTIAL OF SUCH A
STORM.

THE WEST WILL BE A TALE OF TWO REGIONS, WITH THE SOUTHWEST
CONTINUING A HIGH-N-DRY STREAK, AND THE NORTHWEST BACK IN THE
THICK OF ONSHORE FLOW. UNTIL THE OVERALL PATTERN RELAXES OR
RESHUFFLES, WHAT YOU SEE IS WHAT YOU GET IN THE WEST.

Unfortunately, this was created before the last European model run.  I really don't understand why they would work all this up just before the best model runs.  Talk about idiotic.

Yeah, policy is policy. I think we'll have a good idea by the 0z runs tonight if this one is for real, but overnight runs were very discouraging, to say the least....

I dont really think it is idiotic. They are basically saying the possibility is there and they are not going to let one run dictate what they say 5 days out. Im sure they know the euro has been swinging back and forth between the 0z and 12z runs as has been stated in here. They are probably riding the GGem for now.

You don't think it is idiotic to put out a statement that is so official for the entire country that is only produced once a day, one hour before the model with the highest accuracy runs?  This is pretty much why we also have the model with the lowest degree of accuracy of any of the major models too, because we are ok with settling for things that don't make sense, just because.

The Euro run pattern continues with the 12z closer in to the coast and 0z more OTS for the 

last several days. The important runs will be coming up in the next few days to see

what the Euro finally settles on. The key to watch for will be the first 12z run that is more OTS or 

the first 0Z that is further west.

Guess we all forgot that the models wont have complete sampling till 12z/0z saturday huh? Relax people models are going to waver back and forth, chris thanks for reminding everyone here as well the pattern of the 12z/0z EURO. Lets all take a deep breathe and just take it easy till tommorow

Actually..no,I dont. Yes, its an official statement but it doesnt say anything is set in stone. They see the capability of this one. They just arent putting any stock into any given model run 5 days out.

I will tell you this.. It was late at night and the Weenie inside Cisco got the best of him!! Hahahaha

The best we can probably say right now is that all the models are suggesting a rapidly deepening cyclone 

will be somewhere off the coast next week.
