Snowfall totals from TWC.

I have family in CT that says the weatherman says they can get 20 inces of snow..how come the 2 differ????

[brunota2003]

It depends on where your family is at...the further from the coast, the lesser snows, but parts of CT could see 1 to 2 feet of snow (12 to 24 inches).

You're confusing a forecast (the map above) with a possibility of heavier snow. Yes, 10-15 inches would be the expected amount across the region (that's the forecast), but some areas COULD get 20" or more.

[StormingB81]

They are on the Coast. Near New Haven

Anyone have any good webcam links from NYC, Hartford, or Boston?

AREAS AFFECTED...DE...NJ...EXTREME ERN PA...WRN LONG ISLAND...SERN
NY...SWRN CT

CONCERNING...HEAVY SNOW

VALID 261156Z - 261800Z

HEAVY SNOW WITH HOURLY RATES AROUND ONE INCH WILL DEVELOP NWD THIS
MORNING...REACHING DOVER DE/MILLVILLE NJ AROUND 15Z...CNTRL NJ AND
FAR ERN PA 15-18Z AND SERN NY...SWRN CT AND NYC AROUND 18Z. HIGHEST
PROBABILITY FOR THE HEAVIEST BANDS SHOULD EXIST IN A 30-40 MILE
CORRIDOR CENTERED FROM NEAR MILLVILLE NJ-POINT MIDWAY BETWEEN
LAKEHURST/TRENTON NJ-WHITE PLAINS NY THROUGH 21Z.

DAYBREAK SURFACE ANALYSIS REVEALED A DECIDEDLY WWD SHIFT IN MAX
PRESSURE FALLS OVER THE PAST FEW HOURS INTO ERN NC/SERN VA. THIS
COULD SIGNAL THAT THE DEVELOPING LOW WILL TRACK ALONG WRN ENVELOPE
OF SHORT-TERM GUIDANCE SOLUTIONS...PASSING JUST E OF HATTERAS AROUND
15Z THEN JUST EAST OF NORFOLK BY 18Z. THIS MAY HAVE IMPACTS ON
WHERE THE HEAVIER SNOWBANDS ULTIMATELY EVOLVE AND THE 03Z SREF
GUIDANCE SHOWING A SLIGHTLY WWD SHIFT OF HEAVIEST SNOWFALL RATES MAY
BE CORRECT.

TO FURTHER ENHANCE SNOWFALL RATES...RUC FORECAST SOUNDINGS AND
CROSS-SECTIONS INDICATE THAT BOTH SLANTWISE AND UPRIGHT CONVECTIVE
CHANCES WILL INCREASE BY MID-AFTERNOON. THIS MAY YIELD ISOLATED
THUNDERSTORMS/DEEPER CONVECTION AS THE LARGE-SCALE PV-ANOMALY
BECOMES COINCIDENT WITH THE FRONTOGENETIC BAND.

Anyone have any good webcam links from NYC, Hartford, or Boston?

Yes,it would be very good to see on real time what is going on in those and other cities.I dont have links

[tomboudreau]

The forecast discussion from NWS Boston is pretty ominous sounding. Especially with the mention of a gravity wave possibly setting up this evening...

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
916 AM EST SUN DEC 26 2010

.SYNOPSIS...
A DANGEROUS WINTER STORM WILL BE AFFECTING SOUTHERN NEW ENGLAND
THIS AFTERNOON INTO MONDAY. A LOW PRESSURE WILL INTENSIFY OFF THE
NORTH CAROLINA COAST THIS MORNING THEN BECOME A VERY INTENSE
STORM AS IT PASSES JUST SOUTHEAST OF NANTUCKET MONDAY MORNING. THE
LOW SHOULD PULL AWAY LATER MONDAY BUT VERY WINDY CONDITIONS WILL
CONTINUE INTO TUESDAY. A MODERATING TEMPERATURE TREND WILL DEVELOP
DURING THE REST OF THE WEEK AS HIGH PRESSURE BUILDS ACROSS THE
EASTERN SEABOARD.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

-- Changed Discussion --
AT 9 AM LIGHT SNOW CONTINUES TO DEVELOP OVER THE REGION IN
RESPONSE TO A COMBINATION OF COOLING CLOUD TOPS VIA WARM AIR
ADVECTION ALONG WITH A COASTAL FRONT BEGINNING TO SET UP OVER
NORTHEAST MA WITH SFC WNDS NNW AND OFSHR WNDS NE. EXPECT COVERAGE
OF SNOW TO INCREASE AS THE MORNING PROGRESSES BUT 06Z NAM/GFS AND
09Z SREF ALL SUGGEST MODERATE TO HEAVY SNOW SHOULD HOLD OFF UNTIL
4-7 PM TODAY FROM SOUTHWEST TO NORTHEAST. THIS MATCHES UP WELL
WITH LATEST SATELLITE AND RADAR TRENDS UPSTREAM.

LATEST WATER VAPOR AND IR IMAGERY SHOWING AN IMPRESSIVE CYCLONE DEVELOPING
OVER THE MID ATLC WITH A NOTABLE BAROCLINIC LEAF STRUCTURE
SETTING UP OVER DE/NJ AND ERN PA AT 9 AM. THEREFORE SNOW SHIELD
SHOULD EXPAND NORTHWEST ACROSS THIS AREA THIS MORNING AND
EVENTUALLY INTO CT. GIVEN IMPRESSIVE DYNAMICS SEEN ON LATEST SATELLITE
IMAGERY THE RESPONSE AT THE SURFACE IS JUST AS POTENT WITH MESO
ANALYSIS INDICATING PRES FALLS UP TO 7MB IN THE PAST 3 HRS OFF THE
VA/NC COAST. 06Z AND 09Z MODEL RUNS CONTINUE IMPRESSIVE
CYCLOGENESIS JUST OFFSHORE TODAY AND TONIGHT WITH INCREDIBLE
MID LEVEL HEIGHT FALLS TRACKING VERY CLOSE TO NANTUCKET OVERNIGHT /HGHT
FALLS OF THIS MAGNITUDE LAST SEEN WITH DEC 2005 STORM/.

THESE PRES FALLS WILL CONTINUE TO INCREASE TODAY AND TRACK
NORTH-NORTHEAST. THIS WILL LIKELY SET THE STAGE FOR A STRONG
COASTAL FRONT TO DEVELOP SOMEWHERE ACROSS EASTERN MA AND RI LATER
THIS AFTERNOON. THE COASTAL FRONT WILL LIKELY BE STRONG TO INTENSE
GIVEN THE RELATIVELY WARM AIRMASS JUST OFFSHORE COMBINED WITH COLD
TEMPS AND DEW PTS AS NEARBY AS WESTERN MA AND SOUTHWEST NH. IN
ADDITION 06Z NAM/GFS AND 09Z SREF ALL SUPPORT A DEFORMATION ZONE
AND ASSOCIATED FGEN SETTING UP ACROSS EAST-CENTRAL MA INTO RI AND
EASTERN CT 21Z-00Z TODAY. THE 06Z IS ON THE WEST EDGE OF THIS AND
THE 06Z NAM IS FARTHER E. LOCATION OF DRY SLOT WILL BE CRITICAL
WITH CURRENT INDICATIONS FOR THIS DRY SLOT TO MOVE ACROSS THE CAPE
AND ISLANDS. THIS WOULD SUPPORT THE STRONGEST SNOW BANDS FROM
BOSTON TO PROVIDENCE TO POSSIBLY AS FAR WEST AS BDL-ORH-MHT. IN
ADDITION TRACK OF 700 MB LOW ACROSS NANTUCKET SUPPORTS THIS AREAL
COVERAGE. NEVERTHELESS HEAVY SNOW BANDS BEGINNING 21Z-00Z TODAY
AND CONTINUING INTO TONIGHT WILL HAVE THE POTENTIAL TO YIELD
HOURLY SNOWFALL RATES OF 2-4 INCHES PER HOUR...AND PERHAPS EVEN
HIGHER IF COASTAL FRONT AND MID LEVEL DEFORMATION/FGEN OVERLAP FOR
A GIVEN TIME. ANYTIME A STRONG COASTAL FRONT SETS UP COMBINED WITH
IMPRESSIVE PRES FALLS WILL HAVE TO MONITOR FOR POSSIBLE GRAVITY
WAVE TO MOVE UP THE COASTLINE LATER TODAY/THIS EVENING WHICH WILL
ENHANCE SNOWFALL AND WIND FURTHER.

...HAZARDS...
ALSO GIVEN LOCATION OF EXPECTED COASTAL FRONT AND DRY
SLOT MAY HAVE TO PULL BACK BLIZZARD WARNING TO THE I95 /BOSTON-
PROVIDENCE/ CORRIDOR. HOWEVER WILL EVALUATE FULL 12Z GUIDANCE
BEFORE ANY CHANGES. OTHERWISE PREVIOUS FORECAST ON TRACK WITH
CURRENT OBSERVATIONS.
-- End Changed Discussion --





&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
THERMAL PROFILES TONIGHT WILL BE CRITICAL TO EXPECTED IMPACTS
ACROSS SOUTHEAST MA. 00Z GFS LOOKS TO BE VERY WARM AT 925 MB AND
850 MB WHEN COMPARED TO THE OTHER 00Z GUIDANCE...AND WAS
DISCOUNTED FOR NOW. DID ADJUST THE TRACK SLIGHTLY FARTHER WEST...
WHICH REDUCED EXPECTED SNOW ACCUMULATIONS ACROSS CAPE COD AND THE
ISLANDS. AS A RESULT DECIDED TO DROP THE WINTER STORM WATCH AS
CONFIDENCE IS GROWING THIS AREA WILL NOT SEE SIGNIFICANT SNOWFALL.

BRISTOL AND PLYMOUTH COUNTIES ALSO PRESENT A DIFFICULT SNOWFALL
FORECAST. INTRODUCED THE POSSIBILITY FOR SOME RAIN MIXING IN WITH
THE SNOW AND REDUCED SNOW ACCUMULATIONS HERE SLIGHTLY. THE GRADIENT
WILL BE VERY TIGHT THOUGH.

ELSEWHERE...MAINTAINED THE EXISTING BLIZZARD AND WINTER STORM
WARNINGS. CONSIDERED EXPANDING THE BLIZZARD WARNING FARTHER
WEST...BUT JUST DO NOT THINK THE SUSTAINED WIND CRITERIA WILL BE
MET THAT FAR INLAND FOR A STORM OFF THE COAST. WIND GUSTS WILL
MOST LIKELY APPROACH 40-45 MPH THIS AFTERNOON AND OVERNIGHT.

A HIGH WIND WARNING CONTINUES FOR CAPE COD AND ALL OF THE
ISLANDS. IT IS NOT A BLIZZARD WARNING BECAUSE THE HIGHEST WINDS
MAY OCCUR DURING THE PERIOD OF RAINFALL.

SNOW SHOULD TAPER OFF FROM WEST TO EAST MONDAY AFTERNOON.

Luis - thanks for all of the updates yesterday about the storm in my area!

Here's some webcams:

Jim Cantore is in Philadelphia!

[tomboudreau]

Jim Cantore is in Philadelphia!

He should be somewhere in between Hartford, Worcester, Boston, and Providence. That area, I feel, is really going to get slammed from this system. Probably an area of far eastern Connecticut, Northern Rhode Island, and south central Massachusetts.

[Stephanie]

Maybe they kept Jim just out of the Blizzard's warning area. It's going to be bad enough.

Thanks Stepth for posting the cams.My cousin is in the hotel where he will be during the storm.I am sure,he will see a never forgetting snowstorm for the rest of his life.

[wx247]

Yes, Stephanie... thanks for the webcams. This is only just the beginning. What a system it will be.

[DFW Stormwatcher]

Anyone have any good webcam links from NYC, Hartford, or Boston?

Just google traffic cams, new jersey, pennsylvania or connecticut. Some great shots from some of the traffic cams up there. Worst seems to be in Philadelphia(Eastern Penn) , New jersey, and long island at the moment. Starting to accumulate in Connecticut as well, eastern long island has the very worst conditions atm.


http://www.trafficland.com/city/HVN/index.html(southern conn., can move the map to any traffic cam in connecticut. Really you can move the map anywhere, to any of the surrounding states and it will show the location of the cameras. So the above is the only link you need, just start panning around once you've got a map, Long island is straight south of the map in the link.

[cycloneye]

Football game was postponed in Philadelphia.
