THE MAJOR SYSTEM AFFECTING CHRISTMAS DAY TRAVEL IS RAMPING UP OVER
THE SOUTHEASTERN U.S. THIS AFTERNOON AND IS EXPECTED TO CONTINUE
TO INTENSIFY AS THE DAY PROGRESSES. PLACES ACROSS THE SOUTHEAST
ARE EXPERIENCING A RARE WHITE CHRISTMAS THANKS TO THIS SNOW
STORM...THOUGH NOT EVERYONE IS HAPPY ABOUT IT. TRAVELERS STRANDED
AT AIRPORTS ACROSS THE EASTERN U.S. HAVE NO OPTION OTHER THAN TO
WAIT FOR THE STORM TO PASS. FOR THOSE IN THE SOUTHEAST THE BULK OF
THE PRECIPITATION WILL HAVE MOVED INT THE ATLANTIC BY SUNDAY
MORNING. HOWEVER...THE MID-ATLANTIC AND NORTHEASTERN U.S. ARE IN
FOR MORE SNOW.

THE UPPER-LEVEL TROUGH THAT IS CURRENTLY SWINGING OVER THE GREAT
LAKES WILL DEEPEN...CLOSING OFF AN UPPER-LEVEL LOW OVER THE OHIO
VALLEY OVER NIGHT SATURDAY INTO SUNDAY MORNING. STRONG ENERGY AT
THE MID-LEVELS WILL HELP SUPPORT AND STRENGTHEN THE SURFACE LOW
THAT IS SET TO TRACK NORTHWARD ALONG THE ATLANTIC COAST ON
SUNDAY...REACHING THE NEW ENGLAND COAST BY EARLY MONDAY. MODERATE
TO HEAVY SNOWFALL IS LIKELY WITH THIS EVENT AS AMPLE ATLANTIC
MOISTURE IS WRAPPED AROUND THE LOW BACK INTO THE COAST. SEVERAL
INCHES OF SNOW IS LIKELY FOR PARTS OF THE NORTHERN MID-ATLANTIC
AND NEW ENGLAND.

SOUTHEAST CONNECTICUT.

* HAZARDS...HEAVY SNOW AND STRONG WINDS...WITH CONSIDERABLE
BLOWING AND DRIFTING OF SNOW AND NEAR ZERO VISIBILITY AT TIMES.

* ACCUMULATIONS...11 TO 16 INCHES...WITH LOCALLY HIGHER AMOUNTS
POSSIBLE IN HEAVIER SNOW BANDS WHOSE EXACT LOCATION IS STILL TOO
EARLY TO DETERMINE. SNOW MAY MIX WITH OR CHANGE TO RAIN AND

EASTERN LONG ISLAND...AND POSSIBLY ACROSS COASTAL SOUTHEAST
CONNECTICUT...WHICH COULD HOLD DOWN AMOUNTS THERE...BUT ONLY
AFTER SIGNIFICANT ACCUMULATIONS HAVE ALREADY TAKEN PLACE.

* IMPACTS...EXTREMELY DANGEROUS TRAVEL CONDITIONS DEVELOPING DUE
TO SIGNIFICANT SNOW ACCUMULATIONS...AND STRONG WINDS CAUSING
CONSIDERABLE BLOWING AND DRIFTING OF SNOW. VISIBILITIES WILL BE
NEAR ZERO AT TIMES...WITH WHITEOUT CONDITIONS EXPECTED. STRONG
WINDS MAY ALSO DOWN SOME POWER LINES...TREE LIMBS...AND
CHRISTMAS DECORATIONS.

* TIMING...LIGHT SNOW WILL LIKELY BEGIN DURING SUNDAY

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A BLIZZARD WARNING MEANS SEVERE WINTER WEATHER CONDITIONS ARE
EXPECTED OR OCCURRING. FALLING AND BLOWING SNOW WITH STRONG
WINDS AND POOR VISIBILITIES ARE LIKELY. THIS WILL LEAD TO WHITEOUT
CONDITIONS...MAKING TRAVEL EXTREMELY DANGEROUS. DO NOT TRAVEL. IF
YOU MUST TRAVEL...HAVE A WINTER SURVIVAL KIT WITH YOU. IF YOU GET
STRANDED...STAY WITH YOUR VEHICLE.

[Nimbus]

Up along the southern Maine coast they are expecting higher accumulations and the wind criteria calls for a Blizzard watch with whiteouts.

FURTHER
SOUTH...SNOWFALL TOTALS OF 12 TO 15 INCHES ARE POSSIBLE. SOME
LOCATIONS MAY RECEIVE UP TO 18 INCHES. HOWEVER...THE BLOWING SNOW
WILL LIKELY LIMIT THE OVERALL DEPTH OF ACCUMULATIONS DUE TO
DRIFTING AND COMPACTION.

[cycloneye]

Look at those very high snowfall totals that are expected for Mass,Rhode Island.

VALID 00Z SUN DEC 26 2010 - 00Z WED DEC 29 2010

DAYS 1-3...

...SOUTHEAST/MID ATLANTIC/NORTHEAST...
MODELS ARE CONVERGING ON A CYCLONE TRACK FOR A LOW FORECAST TO
DEVELOP OFF THE SOUTHEAST COAST TONIGHT AND RAPIDLY INTENSITY
SUNDAY/SUNDAY EVENING OFF THE MID ATLANTIC/LONG ISLAND/NEW ENGLAND
COAST. EVERY OPERATIONAL MODEL SOLUTION RESULTS IN A HEAVY SNOW
FORECAST ACROSS THE MID ATLANTIC AND NORTHEAST...WITH
PROBABILITIES INCREASING FOR AN AXIS OF 1-2 FEET OF SNOW TO OCCUR.
THE METRO AREAS FROM NEW YORK TO BOSTON AND PORTLAND MAINE HAVE
THE HIGHEST PROBABILITY OF HEAVY SNOW/HEAVIEST FORECAST
ACCUMULATIONS...AND THE HIGHEST RESULTANT IMPACT. WASHINGTON DC
AND PHILADELPHIA INTO INTERIOR NY/VT/NH ARE IN A TIGHT QPF
GRADIENT WHERE SLIGHT ADJUSTMENTS IN THE CYCLONE TRACK AND
RESULTANT PLACEMENT OF THE MID LEVEL FRONTOGENESIS AXIS WILL HAVE
A SIGNIFICANT IMPACT ON THE ACCUMULATIONS.

A WELL DEFINED AXIS OF 850-500 MB FRONTOGENESIS AND DEFORMATION
AXIS SUPPORTS THE SNOW RAPIDLY INCREASING WITHIN A BAND WITHIN AN
AREA OF STRONG 700 MB THETA-E ADVECTION AND CONVERGENCE IN ADVANCE
OF THE LOW OVER THE MID ATLANTIC STATES SUNDAY INTO NEW
YORK/SOUTHERN NEW ENGLAND SUNDAY AFTERNOON...CONTINUING UP INTO
MAINE SUNDAY NIGHT.
THE PERIOD OF MOST RAPID DEEPENING SUNDAY AFTERNOON AND EVENING
FAVORS THE DEVELOPMENT OF A BAND OF INTENSE 1-2 INCH PER HOUR
SNOWFALL RATES IN NY/LONG ISLAND INTO SOUTHERN NEW ENGLAND...WITH
PEAK FRONTOGENESIS SHOWN IN THE 18Z NAM/GFS ACROSS LONG ISLAND TO
SOUTHEAST NEW ENGLAND DURING THIS PERIOD. THE MODEL CONSENSUS
SHOWS A CHANGE OVER FROM SNOW TO RAIN OVER CAPE COD MA AND THE
ISLANDS...KEEPING POTENTIALS NOW AMOUNTS LOWER THERE. THIS IS
ALSO THE CASE FOR EASTERN NC...WITH THE 850 MB LOW TRACK ONSHORE
OVERNIGHT TO 12Z SUN SUGGESTING THE CHANGEOVER TO SNOW OCCURS ONCE
THE LOW PASSES IN FAR EASTERN NC/COASTAL SOUNDS...WITH SUSTAINED
SNOW FURTHER NORTH IN CENTRAL NC AND SOUTHEAST VA ABOUT A DEGREE
TO THE LEFT OF THE 850 MB LOW TRACK.

THE MANUAL GRAPHICS USED A BLEND OF THE 12Z NAM/00-12Z ECMWF/12Z
ECMWF ENSEMBLE MEAN/12Z CANADIAN REGIONAL GEM/12Z UKMET QPFS AND
THERMAL PROFILES FOR THE SNOWFALL TOTALS
ACROSS THE EASTERN US. THE 12Z GFS HAD THE HIGHEST TOTAL
PRECIPITATION DUE TO BOTH MORE RAPID DEEPENING THAN OTHER
SOLUTIONS AND A SLIGHTLY SLOWER/FURTHER WEST LOW TRACK.
THE 12Z GEFS MEAN AND 18Z GFS ARE MUCH LOWER THAN THE OPERATIONAL
12Z GFS QPF ACROSS NJ...AND IN BETTER AGREEMENT WITH THE DOMINANT
MODEL/09-15Z SREF MEAN CLUSTER.
