I've been noticing more people paying attention and posting about winds at like 900/800mb for the coastal storm and getting all amazed and such...b/c of Sandy I think people are looking more into this but the thing is this time of year the winds at the llvl's we're looking at is not unheard of and in fact is pretty common...it's just it's more difficult to mix most of those winds down.

You saw the soundings for CHH right?

hotdog.gif is what it means.... Canadian is breezy

I know I don't have the best maps out there but I'm only limited as far as my resources go and try to do the best with what I have available to me. I also spend a great deal of time with how I want to make them and get frustrated with how they look so I usually do several do-overs and get pissed off.

Just giving you a hard time. You're also not providing maps for clients that pay for them.

The it would probably end up being too far east for me. It's like threading a needle it seems.

It would be nice to see this bomb over the benchmark. Phil would be sniffing ozone and blown into Cape Cod Bay while Rev and I rip S+. That will take a lot of work and definitely isn't the most likely situation but worth watching for lol.

im working in albany this week so im hoping to see something even though albany is in the valley still like seeing this

WEDNESDAY NIGHT INTO THURSDAY...12Z MODEL RUNS OF THE GFS/ECMWF SHOW

THAT THE PROGRESSION OF THIS POSSIBLE NOREASTER IS MUCH SLOWER

COMPARED TO THE 00Z RUNS. LIKELY POPS FROM SOUTH TO NORTH WILL

PROGRESS...AS WE GO THROUGH WEDNESDAY EVENING INTO THURSDAY MORNING.

00Z-12Z THURSDAY...RAIN/SNOW MIX PTYPES ARE LIKELY FOR VALLEY

LOCATIONS...AND SNOW LIKELY FOR HIGH TERRAIN AROUND THE ALBANY

AREA. T850 AND T925 TEMPS WILL RISE ABOVE 0C AROUND 12Z THURSDAY

FOR VALLEY LOCATIONS...AS A DOWNSLOPING EAST TO EAST NORTHEAST WINDS

WILL HELP TO WARM VALLEY LOCATIONS. LOW TEMPS WEDNESDAY EVENING WILL

RANGE FROM UPPER 20S FOR HIGH ELEVATIONS TO LOWER AND MID 30S FOR

THE VALLEY LOCATIONS.

NATIONAL WEATHER SERVICE TAUNTON MA

430 PM EDT SAT NOV 3 2012

.SYNOPSIS...

A NORTHWEST FLOW OF MAINLY DRY BUT COLDER WEATHER WILL DOMINATE

THROUGH SUNDAY INTO EARLY NEXT WEEK. A COASTAL STORM WILL LIKELY

IMPACT THE REGION WED AND THU WITH HEAVY RAIN AND STRONG NORTHEAST

WINDS ALONG THE COAST. A PERIOD OF HEAVY WET SNOW IS POSSIBLE ACROSS

THE HIGHER TERRAIN OF WESTERN MASSACHUSETTS AND SOUTHWEST NEW

HAMPSHIRE.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...

4 PM UPDATE...

CYCLONE NEAR NOVA SCOTIA WILL CONTINUE TO CIRCULATE A DRY AND COOL

AIRSTREAM ACROSS SOUTHERN NEW ENGLAND TONIGHT. CLOUDS WILL ERODE

SOMEWHAT WITH THE LOSS OF DIURNAL HEATING...HOWEVER SOME CLOUDINESS

WILL LIKELY PERSIST ACROSS THE UPSLOPE REGIONS OF THE HIGHER TERRAIN

OF CT/MA AND SOUTHWEST NH. WINDS WILL SLACKEN AS WELL WITH SUNSET

EXCEPT CAPE COD AND THE ISLANDS WHERE WIND TRAJECTORY OVER THE

RELATIVELY WARMER COASTAL WATERS WILL PROMOTE MORE BLYR MIXING.

TEMPS WILL BE ABOUT 5 DEGS COOLER THAN NORMAL TONIGHT WITH MOST

LOCATIONS IN THE 30S EXCEPT AROUND 40 IN BOSTON ALONG WITH CAPE COD

AND THE ISLANDS.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...

SUNDAY...

SOME SUBTLE HEIGHT RISES ALOFT BUT STILL CYCLONIC FLOW ALONG WITH

COLD TEMPS ALOFT SHOULD YIELD ANOTHER ROUND OF DIURNAL CLOUDS

ESPECIALLY IN THE UPSLOPE HIGHER TERRAIN OF WESTERN CT-MA AND

SOUTHWEST NH. MORE SUNSHINE IN THE COASTAL PLAIN. COLD AIR ADVECTION

CONTINUES SO TEMPS A FEW DEGS COOLER THAN TODAY. PGRAD CONTINUES SO

EXPECT NW WINDS TO BECOME GUSTY DURING PEAK HEATING HOURS.

SUN NIGHT...

PROBABLY THE COLDEST NIGHT OF THIS EARLY FALL SEASON AS COLDER AIR

BEGINS TO MIGRATE SOUTHWARD WITH POLAR VORTEX OVER SOUTHEAST QUEBEC

BUILDING TOWARD NEW ENGLAND. WINDS WILL ONCE AGAIN SLACKEN WITH

SUNSET BUT LIKELY REMAIN GUSTY OVER THE CAPE AND ISLANDS AS WINDS

SHIFT TO THE NE AS LOW PRES DVLPS SOUTH OF NEW ENGLAND. THIS WIND

SHIFT MAY ALSO INCREASE CLOUDS /OCEAN EFFECT CLOUDS/ ACROSS

SOUTHEAST MA IN RESPONSE TO CAA ON NE FLOW OVER THE RELATIVELY WARM

OCEAN WATERS. HOWEVER DRY WEATHER WILL PREVAIL.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...

HIGHLIGHTS...

* COOLER TEMPS AT BEGINNING OF THE WEEK...POSSIBLE FROST/FREEZE

HEADLINES FOR REMAINING AREAS.

* STRONG COASTAL STORM TO IMPACT NEW ENGLAND BY MID-WEEK.

* PATTERN CHANGE BY NEXT WEEKEND.

DETAILS...

MODELS/PATTERN...

12Z MODEL GUIDANCE IS IN GOOD AGREEMENT FOR THIS PORTION OF THE

FORECAST. THE 12Z GFS HAS TRENDED MORE TOWARDS THE 04.00

EC...HOWEVER STILL IS SLIGHTLY FASTER. OVERALL MODELS ARE SHOWING AN

UPPER LEVEL TROUGH OVER THE REGION BEGINNING ON MONDAY MOVING INTO

THE MARITIMES BY THURSDAY. STRONG COASTAL STORM WILL MAKE ITS WAY UP

THE EASTERN SEA BOARD ON WED AND MOVE INTO SOUTHERN NEW ENGLAND BY

WED NIGHT INTO THURSDAY...EXITING BY FRIDAY. STRONG RIDGING ACROSS THE

MIDWEST WILL SLOWLY PUSH ITS WAY INTO SOUTHERN NEW ENGLAND BY

SATURDAY/SUNDAY.

MONDAY-TUESDAY...HIGH CONFIDENCE.

QUIET WEATHER WILL BE ON TAP FOR THIS PERIOD AS HIGH PRESSURE WILL

BUILD INTO THE REGION. QUICK MOVING SHORTWAVE ACROSS THE MID

ATLANTIC WILL REMAIN OFFSHORE FOR THE REGION...HOWEVER IT WILL

SWITCH WINDS TO A MORE NW COMPONENT. THIS WILL ALLOW FOR CAA TO OCCUR

THROUGH THE PERIOD KEEPING HIGH TEMPS IN THE MID 40S. MONDAY NIGHT

TEMPS LOOK TO BE THE COLDEST AS A FEW TEMPS WILL DROP TO THE TEENS

ACROSS THE NW....WITH UPPER 20S ALONG THE SOUTH COAST AND CAPE.

WOULD NOT BE SURPRISED TO SEE A FEW FROST/FREEZE HEADLINES FOR

BOSTON...PROVIDENCE...NARRAGANSETT REGION AS WELL AS THE CAPE. THIS

IS DUE TO THE STRONG CAA/CLEAR SKIES AND LIGHT WINDS. TEMPS ON

TUESDAY NIGHT WILL BE SLIGHTLY WARMER.

WEDNESDAY INTO THURSDAY...LOW TO MODERATE CONFIDENCE.

CONFIDENCE IS INCREASING THAT A COASTAL STORM WILL AFFECT SOUTHERN

NEW ENGLAND DURING THE WED/THUR TIME FRAME. AS STATED EARLIER

SEVERAL MODELS ARE COMING TOGETHER AND ARE IN GOOD

ALIGNMENT...HOWEVER THERE IS STILL SOME UNCERTAINTY WITH THE TRACK

AND TIMING OF THIS SYSTEM.

POTENTIAL HAZARDS:

* STRONG TO DAMAGING WINDS...ESP ACROSS THE SOUTHEAST.

* INTERIOR ACCUMULATING WET SNOW...ESP ACROSS HIGHER TERRAIN IN WEST.

* FRESH WATER FLOODING ESP ACROSS EASTERN HALF OF THE REGION.

* MINOR TO MODERATE COASTAL FLOODING ALONG EAST COAST.

MAIN FOCUS OF THIS FORECAST IS ON THE POTENTIAL FOR STRONG DAMAGING

WINDS AND THE INTERIOR POSSIBILITY OF WET SNOW. AS THE UPPER LEVEL

SHORTWAVE MOVES OUT OF THE SOUTHEAST AND BEGIN ITS NORTHWARD

TRACK...A SURFACE LOW DEVELOPS AND HUGS THE EASTERN COASTLINE AS IT

HEADS INTO SOUTHERN NEW ENGLAND BY WED. STILL SOME DIFFERENCE IN THE

TRACK OF THE SURFACE LOW. THE GFS TRACK IS THE CLOSEST TO THE

INTERIOR AS THE EC WAS CLOSER TO THE BENCHMARK. HOWEVER THE 12Z GFS

TRENDED CLOSER TO THE EC FOR ITS RUN AND THEREFORE BELIEVE THAT THE

SYSTEM WILL TRACK CLOSER TO THE BENCHMARK...AND A COLDER SOLUTIONS.

ALTHOUGH TIMING DIFFERENCE...HAVE HIGH CONFIDENCE THAT PRECIP WILL

OCCUR AREA WIDE BY WED NIGHT/THURS. THIS SYSTEM WILL OCCLUDED AND

BECOME VERTICALLY STACKED OVER SNE...WHICH WILL DELAY THE FORWARD

MOVEMENT. THIS WILL INCREASE THE POTENTIAL FOR FLOODING ESP FRESH

WATER AS WELL AS COASTAL FLOODING...AS IT WILL SIT OVER MULTIPLE

TIDES FROM WED INTO THURS. PWAT VALUES ARE INCREASING AS

WELL...SHOWING BETWEEN 1 TO 1.5 INCHES OF PRECIP.

BECAUSE OF THE COLDER SOLUTION AND THE INCREASE OF PRECIP...BELIEVE

THAT THE POTENTIAL FOR SNOW IS INCREASING. AS THE SYSTEM MOVES

NORTHWARD...IT WILL TAKE SOME TIME FOR THE WARM AIR TO MOVE

NORTHWARD...SO AT ONSET WHERE TEMPS WILL BE COLD ENOUGH AND PRECIP

FALLING...EXPECT SOME WET SNOW. TIMING WILL BE A CONCERN AS IF IT

WILL IMPACT ANY OF THE COMMUNITIES OR NOT...HOWEVER STILL SOME

UNCERTAINTY. BELIEVE THAT THE TEMPS WILL INCREASE THROUGHOUT THE

DAY ON WED/WED NIGHT AS ONSHORE FLOW MOVES THROUGH...ALLOWING FOR

MORE OF A RAIN EVENT. BUT AS THE SYSTEM EXISTS ON THURSDAY COULD SEE

SOME MORE SNOW ON THE BACK SIDE. BECAUSE OF THE AMOUNT OF MOISTURE

ASSOCIATED WITH THIS SYSTEM...MAY SEE SEVERAL INCHES OF

ACCUMULATION ACROSS THE WESTERN INTERIOR.

DAMAGING WINDS IS A MAJOR CONCERN WITH THIS SYSTEM AS THE PRESSURE

GRADIENT FROM THIS SYSTEM WILL BE STRONG FROM THE DEEPENING LOW

MOVING UP THE COAST AND THE STRONG ANOMALOUS HIGH PRESSURE SITTING

OVER THE MARITIMES. AS THE LOW MOVES CLOSER TO SNE...925 MB HAS A

JET OF 70 KTS OF WIND OVER THE SOUTH COAST/CAPE/ISLANDS. THIS IS

SHOWN IN SEVERAL OF THE MODELS AS WELL AS THE ENSEMBLES. BUFKIT

SOUNDINGS SHOW THESE WNDS MIXING DOWN TO THE SURFACE ESP ACROSS THE

CAPE AND ISLANDS. BACKED WINDS OFF A LITTLE BIT IN THE FORECAST BUT

WOULD NOT BE SURPRISED TO SEE THESE STRONG WINDS PLAY OUT.

KEPT THE MAIN JIST OF THE PREV FORECAST OF THIS TIME FRAME...HOWEVER

MADE SOME MODIFICATIONS. HAVE TRENDED TEMPS TO A MORE COLDER

SOLUTIONS AS THIS IS WHAT THE MODELS ARE SHOWING. HAVE ALSO

INCREASED PRECIPITATION AMOUNTS BY A WHOLE INCH AS IT APPEARS THAT

THERE IS SOME BANDING POSSIBILITIES ACROSS THE EAST COAST FROM

PERHAPS A COASTAL FRONT TRYING TO FORM. HAVE ALSO INCREASED THE

WINDS AS MODEL DATA HAS BEEN CONSISTENT WITH AN ANOMALOUS LOW LEVEL

JET MOVING THROUGH. FINALLY BECAUSE OF THE COLDER TREND AND MORE

PRECIP...HAVE INCREASED THE POTENTIAL FOR HEAVY WET SNOW ACROSS THE

WESTERN INTERIOR.

FRIDAY AND BEYOND...MODERATE CONFIDENCE.

COASTAL STORM MAY LINGER INTO FRIDAY BUT SHOULD EXIT OUT BY THE

WEEKEND. OVERALL LOOKS AS IF A PATTERN CHANGE IS IN STORE FOR

SOUTHERN NEW ENGLAND AS STRONG TROUGH BEGINS TO DIG INTO THE WESTERN

CONUS...ALLOWING FOR AN INCREASE IN RIDGING ACROSS THE NORTHEAST.

Yeah like I said earlier... As it approaches I can tell you were to drive to experience maximum snow if that plays out as they said. :) Only a 15 minute drive from ALB and you can be at 1500' on the Helderberg Escarpment. I'm sort of on the northwest edge of that at 1k feet.

im working in albany this week so im hoping to see something even though albany is in the valley still like seeing this

WEDNESDAY NIGHT INTO THURSDAY...12Z MODEL RUNS OF THE GFS/ECMWF SHOW

THAT THE PROGRESSION OF THIS POSSIBLE NOREASTER IS MUCH SLOWER

COMPARED TO THE 00Z RUNS. LIKELY POPS FROM SOUTH TO NORTH WILL

PROGRESS...AS WE GO THROUGH WEDNESDAY EVENING INTO THURSDAY MORNING.

00Z-12Z THURSDAY...RAIN/SNOW MIX PTYPES ARE LIKELY FOR VALLEY

LOCATIONS...AND SNOW LIKELY FOR HIGH TERRAIN AROUND THE ALBANY

AREA. T850 AND T925 TEMPS WILL RISE ABOVE 0C AROUND 12Z THURSDAY

FOR VALLEY LOCATIONS...AS A DOWNSLOPING EAST TO EAST NORTHEAST WINDS

WILL HELP TO WARM VALLEY LOCATIONS. LOW TEMPS WEDNESDAY EVENING WILL

RANGE FROM UPPER 20S FOR HIGH ELEVATIONS TO LOWER AND MID 30S FOR

THE VALLEY LOCATIONS.

BTV's take is similar to ALY's...rain/snow for valleys, snow or wintery mix for higher elevations. Going to have to watch the track, big upslope potential with this one once it moves north.

Wednesday Night

Rain or snow likely. Lows around 30. Chance of precipitation 60 percent.

Thursday

Rain or snow likely. Highs in the lower 40s. Chance of precipitation 60 percent.

Thursday Night

Cloudy with a chance of rain or snow. Lows in the lower 30s. Chance of precipitation 40 percent.

"At this time...leaning with rain or rain/wet snow mix for the valleys and snow or mixed precipitation for the higher terrain with accumulating snows possible...especially over the Adirondacks. Best forcing with this event shaping up early in the period (wednesday night into early thursday) when fgen greatest. Have raised probability of precipitation to likely for most of the area for Wednesday night/Thursday time periods. System then slowly departs through the Canadian Maritimes Friday. Cyclonic flow and cold air advection will result in some snow showers...mainly over the higher elevations and west facing slopes."

Wow, point-and-click bringing snow as a possibility even here in Chestnut Hill

  • Tuesday Night

    A chance of snow before 5am, then a chance of rain and snow. Partly cloudy, with a low around 31. Chance of precipitation is 30%.

  • Wednesday

    Rain and snow. High near 47. Chance of precipitation is 80%.

  • Wednesday Night

    Rain likely. Cloudy, with a low around 37. Breezy. Chance of precipitation is 70%.
