Oct Banter/Obs IV...........

the CMC tries to do this once every autumn it seems... It takes a full bird TC right up into a baroclinic wall, fuses the two together, and produces some kind of hyper scenario of 77F DP in warm sector while it is snowing like a blizzard over western NF.

Never seen that happen, though the annals suggest it has happened before. Gotta figure something like that to be exceptionally rare... Although, the "Perfect Storm" as it were was similar, just didn't have the cold air... And it also went back to warm phase at the end, too... weird.

Sounds like a "stemwinder" to me.

CMC AND UKMET ALONG WITH A CONSIDERABLE NUMBER OF ECMWF ENS

MEMBERS INDICATE THE POTENTIAL OF TROPICAL DEVELOPMENT IN THE NWRN

CARRIBEAN NEXT WEEK. HAVE ADJUSTED SFC PROGS FOR THIS FEATURE

SLOWER THAN THE OPERATIONAL CMC AND UKMET APPROACHING WRN

CUBA/YUCATAN CHANNEL MID NEXT WEEK.

HPC UPDATED PROGS USE A MIXTURE OF 00Z ECMWF/00Z GFS AND 00Z ECMWF

WED/THURS. SOME FRONTAL CHANGE ADJUSTMENTS MADE TO AFTN FINALS

yeah the 00z is pretty funny.

Yeah it was - I was just mentioning how the CMC model seems to do this every year around this time. I remember back in the day, 2003 I think it was, the CMC's day 10 had a hurricane phasing into a regular cold season nor'easter, with marginal thickness from PHL on up - the result was a hyper bomb ...964mb type of thing. You laugh at a day 10 chart's eye candy when you see that.

The days ticked by, some runs came back with it, others morphed the whole thing into just a cold core system with no tropical involvement... It all verified with the December 2003 New England snowstorm, no tropical involvement. Here's the Wikepedia run down on it, taken for what it is worth:

It was a severe nor'easter that impacted the Eastern United States during the first week of the month. It produced heavy snowfall throughout the New England and Mid-Atlantic regions, locally exceeding 40 inches (1 m).[1] The cyclone had complex origins, involving several individual weather disturbances. An area of low pressure primarily associated with the southern branch of the jet stream spread light precipitation across portions of the Midwest and Southeast. The low reached the coast on December 5 and continued to produce snow throughout the Mid-Atlantic. Another system involving the northern branch of the jet stream merged with the initial storm, causing another coastal storm to develop. This storm soon became the primary feature as it intensified and moved northeastward. It reached Cape Cod on December 6, but became nearly stationary through the morning of December 7.[2] It had finally abated by December 8.[3]Conditions surrounding the storm allowed for several bands of heavy snowfall to set up over New York State and New England, including a small area of 4 in (100 mm) per hour snowfall rates in the Hudson Valley. As a result of extremely cold temperatures over the region, snowfall accumulations were generally significant and broke several daily records. At Albany, New York, 12.5 in (320 mm) of snow fell in just one day. Locations affected by the storm commonly picked up 17 to 24 in (430 to 610 mm), with totals occasionally exceeding 30 in (760 mm).[2]

The event led to widespread travel delays from Washington, D.C. to Boston, and around 13 people lost their lives because of the storm.[4] The nor'easter was among the largest early-season winter storms to affect the major East Coast cities on record. Many areas reported blizzard-like conditions.[5]

In the end it was just that the CMC has a kind of TC genesis bias much of the time, and the trough amplitude/depth was probably going to be there either way. This is by no means an analog, but seeing a mid autumn trough steepen along the coast and a TC caught in the flow is pretty typical for the CMC.

That said, there is a nice area of disturbed weather down there. TPC hatches that out with 20% currently.

Decent write-up from NWS State College: http://nws.met.psu.edu/severe/2003/5-6Dec2003.pdf

With a torch like today, its hard to believe November is right around the corner. It just doesn't feel like fall right now. Anyone else feel that way. I mean at this point in other years I would be smelling that burning wood smell from fire places. Just feels like august right now.

Turn that frown upside down!

Snow coming next week, then a hurricane.:thumbsup:

Like these windy days as they help turn the water over on the lakes and ponds. Let's get em cooled off and frozen quick. We're thinking of building another ice boat. Last one was fun but suffered a career ending injury.

Always wanted to try one of those puppies out. Grew up skating and sailing. 2+2!

I did make a hand-sail to use ice skating on a five mile skate trail on a nearby lake a couple winters ago. Skate up wind, stop & put the sail/braces together, pop the chute and whoosh. It's just a little ~3'x3' rig but good fun anyway...

Yeah, it's definitely weird. I remember another late warm stretch a few years back--05 maybe? I just remember barely having a frosting of snow at Christmas that year (at 1200' in central VT), valley locations still having greenish grass, hardly any/no ice on the lakes and ponds and even a very few late-blooming flowers being reported--probaly violets.

Pretty sure it was 05-06 now that I think about it. We made up a lot of ground later in the winter but it was very late in getting going.

Completely agree...Jaffrey (AFN) made it up to 63F today, total torch as we only got down to 47F last night on the campus weather station. I haven't checked today's maximum on my classroom weather station, but I assume we were over 60F on campus at Hampshire Country School given that it was already 58F around noontime. Feels more like early September with the warm days and just slightly cool nights. Not an odor of woodsmoke in the air, any attractive foilage, or any sight of snow in the forecast. Disappointing.

It was 2006-2007. December 2006 was a mega torch with hardly any snow anywhere in New England, even the mountains.
