The differences between the Euro and everything else are insane. Euro is a raging blizzard on the Cape and probably into Plymouth and a part of Bristol County due to OES. NAM, GGEM and GFS really aren't close to that. Either an epic win or the exclamation point on a tough year for the Euro.

Rgem looked good at 0z and then notsogood at 6z.

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...

*/ HIGHLIGHTS...

* EXPLOSIVE CYCLOGENESIS OFFSHORE WILL IMPACT SE MA TUE NIGHT INTO WED

WITH SNOW AND STRONG WINDS

* MILDER WITH RAIN POSSIBLE FRI

* ARCTIC AIR BRIEFLY REENTERS NEW ENGLAND LATE IN WEEKEND

* MILDER AIR OF PACIFIC ORIGIN LOOKS TO DOMINATE MOST OF NEXT WEEK

MAIN FOCUS THIS FORECAST SHIFT IS TUE NIGHT INTO WED TIMEFRAME AS EXPLOSIVE

CYCLOGENESIS OCCURS OFF E COAST. THIS RESULTS IN QUITE A FEW

HEADLINES. THUS...LESS ATTENTION BEYOND WED AND WILL GO LARGELY

WITH A SUPERBLEND FOR THE THU AND BEYOND FORECAST ELEMENTS.

OVERVIEW... REASONABLY GOOD CONSISTENCY WITH ENSEMBLES AND

OPERATIONAL RUNS OF RAPID CYCLOGENESIS OFF EAST COAST IN RESPONSE

TO VIGOROUS SHORT WAVE ENERGY THAT DIVES OUT OF CANADA AND

INTERACTS WITH FRONT OFFSHORE. BOTH ENSEMBLES AND OPERATIONAL RUNS

POINT TO A SURFACE LOW TRACK SOMEWHAT EAST OF THE

BENCHMARK...PERHAPS 50 OR 75 MILES OR SO. PLENTIFUL

MOISTURE...STRONG BAROCLINICITY AND STRONG DIVERGENCE ALOFT WITH

NEGATIVE TILT TROF POINTS TO HEAVY PRECIPITATION NW OF SURFACE

LOW. A MORE BENIGN ALTHOUGH NOT NECESSARILY PRECIPITATION FREE

PATTERN FOLLOWS FOR THE END OF THIS WEEK INTO NEXT WEEK. TUE NIGHT

INTO WED...

AT THIS POINT IN TIME...ISSUE COMES DOWN TO TIMING OF DEEPENING

AND PRECISE TRACK OF SURFACE LOW. ECMWF OP RUNS INCLUDING THE

LATEST 00Z VERSION CONTINUE TO RUN A LITTLE FURTHER W AND HEAVIER

ON THE QPF THAN THE GFS RUNS. UKMET ALSO APPEARS A LITTLE W OF THE

SUITE OF MODEL CONSENSUS. ECMWF 12Z ENSEMBLE MEAN JUST A TAD E OF

00Z OP RUN. HAVE GONE A LITTLE CLOSER TO GFS OP RUN AND ENSEMBLE

TRACK BUT A TAD CLOSER TO THE COAST IN DEFERENCE TO CONSISTENCY OF

ECMWF FROM RUN TO RUN.

HAVE 50 PERCENT CONFIDENCE IN MEETING HIGH WIND AND WINTER STORM

WARNING CRITERIA ON THE CAPE AND ISLANDS. DEBATED BETWEEN WINTER

STORM AND HIGH WIND WATCHES OR BLIZZARD WATCH. BELIEVE A LITTLE

GREATER THAN 50 PERCENT CHANCE OF AT LEAST BLIZZARD CONDITIONS AT

TIMES OVER THE CAPE AND ISLAND AND THINK BLIZZARD WATCH

APPROPRIATE TO HIGHLIGHT POTENTIAL SIGNIFICANCE OF EVENT THERE.

HAVE ADDED A BUFFER OF ZONES IN SE MA AND FAR SE RI WITH A WINTER

STORM WATCH. NOTE THAT THE ECMWF OP RUN WOULD SUGGEST THE NEED OF

A WINTER STORM WATCH TO BOSTON AND PERHAPS EVEN WEST TO WORCESTER

AND ALL OF RI...BUT THIS MODEL SEEMS TO BE ON WESTERN PERIPHERY OF

THE MODEL CONSENSUS.

CONFIDENCE IS RELATIVELY HIGH FOR HIGH IMPACT OVER THE CAPE AND

ISLANDS AND FOR RELATIVELY LOW IMPACT ACROSS SW NH...NW CT AND MA

N AND W OF WORCESTER. CONFIDENCE IS CONSIDERABLY LESS IN THE

GRADIENT REGION IN BETWEEN. THIS LOOKS TO BE STILL ANOTHER STORM

WITH A SHARP SNOWFALL GRADIENT ON THE NW SIDE AND CONFIDENCE OF

EVENTUAL SNOWFALL TOTALS IN THE BOSTON TO PROVIDENCE CORRIDOR IN

PARTICULAR REMAINS QUITE LOW. AS NOTED IN PREVIOUS FORECAST

DISCUSSION...A SLIGHT WOBBLE OF THE SURFACE LOW OR LOCATION OF A

PERIPHERAL DEFORMATION ZONE BAND COULD MAKE A SIGNIFICANT

DIFFERENCE.

SEE COASTAL FLOOD AND MARINE SECTIONS FOR ADDITIONAL SIGNIFICANT

HAZARDS FOR THE TUE NIGHT AND WED STORM.

RGEM doesn't have the dual lobe, without it, there's no western flank like on the Euro.  Tendency this year has been for delayed consolidation which gives a little credence to the Euro but it's really out on its own.

 

Do I get into the OES in South Duxbury?

 

Unless something really changes it looks pretty favorable for OES in Plymouth county.

These bombing lows obviously tend to drop a lot of snow when they go through bombogenesis in a short time period but there is always that one area that sees rates like nowhere else. For instance, New Haven during last year's blizzard was just ferocious. Right now despite the better track being for a place like Nova Scotia, the best snowfall rates are modeled right offshore as this thing drops like 60mb near the benchmark. If the Cape has that going for them if they can eek their way into a death band. It's not all that far from the outer cape and ack.

Just a tiny bit overamped? not to be a downer here but I am guessing one of the reasons the EURO is so far west is it bombs the low to cazy levels like this.

 

I would agree but NCEP is going with the Euro/UK blend entirely but with low confidence.

 

...UPPER TROF BECOMING NEGATIVELY-TILTED OFF THE MID-ATLANTIC

COAST BY TUESDAY NIGHT...

...SURFACE WAVE DEVELOPING OVER THE NORTHEASTERN GULF OF MEXICO...

...COASTAL LOW RAPIDLY INTENSIFYING OFF THE NEW ENGLAND COAST

EARLY WEDNESDAY MORNING...

FINAL PREFERENCE: BLEND OF THE 00Z ECMWF/UKMET

FORECAST CONFIDENCE: BELOW AVERAGE

THE SYNOPTIC PATTERN ENTERING THE WEEK WILL BE HIGHLY AMPLIFIED

WITH A RIDGE ANCHORING THE WEST COAST WHILE A LONGWAVE TROF

ENCOMPASSES THE NORTHERN/CENTRAL ROCKIES EASTWARD TO NEW ENGLAND.

SHORTWAVE ENERGY SLIDING SOUTHEASTWARD ALONG THE EASTERN EXTENT OF

THE UPPER RIDGE IS FORECAST TO GATHER STRENGTH AS IT ROUNDS THE

BASE OF THE TROF OVER THE LOWER MID-ATLANTIC TUESDAY EVENING.

DOWNSTREAM RIDGING WILL EVENTUALLY FORCE THIS SYSTEM NORTHWARD AS

IT QUICKLY BECOMES NEGATIVELY-TILTED ALONG THE COASTAL WATERS OF

THE MID-ATLANTIC. DURING THE EVOLUTION OF THIS SYSTEM...AN INITIAL

SURFACE LOW WILL DEVELOP ACROSS THE NORTHEASTERN GULF OF MEXICO BY

LATE MONDAY WHILE AN EVEN MORE IMPRESSIVE CYCLONE EXPLODES OFF THE

NEW ENGLAND COAST BY EARLY WEDNESDAY. OVERALL...THE MODELS ARE

DEFINITELY IN BETTER AGREEMENT WITH THIS SET OF MODELS VERSUS

YESTERDAY BUT THERE ARE STILL PLENTY OF DIFFERENCES WITH THE TRACK

OF THE LOW OFFSHORE. ONE THING THAT LOOKS FAIRLY CERTAIN IS THE

CYCLONE BOMBING OUT OFF THE EAST COAST SHOULD TRACK EAST OF THE

40N/70W BENCHMARK WHICH HAS BEEN PERSISTENT IN THE PAST COUPLE OF

MODEL CYCLES. THE GUIDANCE STILL HAS SOME DIFFICULTIES HANDLING

WHETHER THE AREA OF LOW PRESSURE NORTH OF THE BAHAMAS WILL MOVE

NORTHWARD WITH THE COASTAL SYSTEM. OVERALL THE LATEST GUIDANCE

SEEMS TO FAVOR SOMETHING SLOWER AND SLIGHTLY MORE WESTWARD OF THE

ENSEMBLE MEANS WHICH NOW APPEAR TO BE ON THE PROGRESSIVE SIDE OF

THINGS. THE 00Z UKMET HAS MADE A MOVE TOWARD THE EAST RELATIVE TO

ITS PREVIOUS RUN WHILE THE 00Z ECMWF HAS DONE THE REVERSE SHIFTING

MORE WEST. THIS ACTUALLY BRINGS THE 00Z ECMWF/UKMET IN REASONABLE

AGREEMENT WITH ONE ANOTHER. THIS PREFERENCE IS DEFINITELY SUBJECT

TO CHANGE AS MODELS CONTINUE TO BE INCONSISTENT WITH THE RAPID

DEVELOPMENT OF THIS COASTAL LOW. UNTIL THE NEXT ROUND OF GUIDANCE

ARRIVES LATER IN THE MORNING...WILL GO AHEAD AND FAVOR THE 00Z

ECMWF/UKMET BUT CONFIDENCE WILL BE REDUCED TO BELOW AVERAGE AS THE

FORECAST HAS BECOME MORE NEBULOUS THAN BEFORE.

...If not, you can surely get the exhaust of your truck piped into your window.

 

Mixed feelings on this one. If it was January I'd be getting my truck washed tomorrow to taunt the weather gods. Want to take the cover off the boat. 

 

Would like to use my new generator once this year. Worst investment ever.

Have been mostly out of the loop on this one all weekend as I didn't have good internet access....but the Euro is definitely the western outlier as I look this morning. The EC ensmebles though are fairly similar the to OP...more amplified than other guidance...though the UKMET does give it reasonable support.

 

American guidance just isn't biting.
