The grids from COLA offer 10cm to 15cm then to straight rain for Montreal.

Im dreaming of a white christmas !!! just ask Irving Berlin in 1940 who wrote the song.. link.. lien.. http://uk.reuters.com/article/burningIssue...E4BL1AD20081222

The last real Christmas snow storm was in 1966 with 32.8 cm. If Patito is right will be 7 cm shy of breaking the record for the date for montreal. this is the link... voici le lien pour la date... http://www.climate.weatheroffice.ec.gc.ca/...Month=12&Day=21

I think that January will be a normal month temp wise for Southern Quebec before it turns colder again late January and Feb. this is from lundbergs blog... Bitter Cold To Be Bottled Up For a Time Monday, 11:30 A.M. The one-two punch of storms that moved across the Midwest and Great Lakes into the Northeast over the past few days has helped pull a strong cold front right off the Gulf Coast, through The Valley, off the East Coast, and down through Florida in the past 24 hours or so, and it is an impressive cold front, indeed! Wind chills along the Gulf coast were close to 10 degrees this morning, and temperatures during the daylight hours stayed below zero in Chicago yesterday! Just as impressive was the dump of snow with these two storms. While northern New England, specifically Maine, largely missed out on all the fun with the first storm, they were walloped with the second one. I think I got my two feet of snow through the weekend, only it was solely with storm number two in parts of Maine! Regardless, there is a carpet of white on the ground now that's not going away any time soon, certainly not through Christmas in most of the areas that cashed in on the snow. Check out the latest snow cover: http://www.weatheroffice.gc.ca/data/analysis/352_50.gif There is one little problem, though. There remains up to now no reasonable form of blocking downstream, as evidenced by a positive North Atlantic Oscillation: http://www.cpc.ncep.noaa.gov/products/prec...index_ensm.html Without out that, the cold can certainly come if other things upstream are conducive for it, but there's no way to sustain that cold. We have seen this time and time again over the past few weeks, especially this month. No doubt the cold overall has won the war in a lot of places, but these spikes of warmth keep occurring, and another couple are on the way as we head to and beyond Christmas. If you look at the ensemble forecasts of the NAO, though, what should catch your eye is the negative trend going forward. That suggests to me that if there's more cold air in the pipeline after the nice warm period across the South and into the East, that it will come, and may actually stick around for more than a few days at a time. Even the Arctic Oscillation is being forecast to turn very negative as we head into the New Year, a signal of renewed pulses of bitter after this period of relaxation in the pattern occurs. http://www.cpc.ncep.noaa.gov/products/prec...ex/ao.sprd2.gif Should that occur as expected, and I have good reason to doubt it, then I'd look for the cold to be reloading in the high latitudes of North America in the coming days, something the GFS ensembles are clearly picking up on: http://www.meteo.psu.edu/~gadomski/ENSTDEP2_6z/tloop.html I don't trust the ensembles too far out, though, so I do wonder aloud why the cold up in Alaska, the Yukon Territory, northern British Columbia and Alberta early to middle portions of next week doesn't come down into the U.S. more forcefully. Perhaps future model runs will change. Regardless, the one thing that isn't likely to change much is the cold in the West this week. The persistent negative PNA pattern clearly implies troughing of one kind or another over the West, where it has been plenty cold and very snowy of late. As a for instance, Spokane, Washington is closing in on three feet of snow for the month, and temperatures are now 5.6 degrees below average. Really, since this all began back on the 12th with the first snow fall, the temperature anomaly is a whopping -16!!! Seattle is less impressive given the raw numbers of just under 10 inches of snow for the month, and a temperature departure of -4. But if you simply look at the last 9 days since the 13th, it's an amazing 13 inches below average. Portland has picked up 4.7 inches of snow, with a monthly temperature departure of 3.2 degrees below the norm. But the last 8 days have been a whopping 11.6 below average, a truly remarkable run of cold. Even coastal locations have gotten in on the act, as Astoria has had over four inches of snow the past few days. Pendleton has 29 inches of snow for the month, and Moses Lake, Washington now has about 6 inches of snow for the month, with temperatures running over 18 degrees below normal in the past 8 days. The cold in the Northwest will ease around Christmas, though it won't completely leave. This should allow snow levels to get up off the valley floor by Christmas Eve, while interior areas remain at risk for at least some snow showers as the parade of disturbances continues. While the cold there holds on as best it can until some more gets let loose on the region down the road a piece, it's not going to warm a lot, given a persistently negative PNA pattern: http://www.cpc.ncep.noaa.gov/products/prec...a/pna.sprd2.gif Face it. It's just time for the Northwest to get winter. Now, for those across the Ohio Valley to the mid-Atlantic states that are begging for snow after having missed out on much of it with the past few storms, I don't have much good news for you going forward. What chance you had in this pattern is now gone, and the cold that's in place will simply go away starting tomorrow night. One storm heads for the Great Lakes Wednesday, pushing a lot of warm air northeastward from the Gulf into the Ohio Valley and into the East. This will eat into the snow piles currently in place, and certainly the snow cover less extensive Christmas morning than it is now from much of Illinois, Indiana, and southern Michigan over to New York and New England. After a cold frontal passage that will allow some cold air to bleed back down into the central Plains, across the Midwest and Great Lakes into the Ohio Valley, New England and the mid-Atlantic states, still another storm cuts for the Great Lakes Saturday. An even more impressive warm surge will precede the cold front attached to this storm, since there won't be nearly as much cold air to shove out of the way. Rain will certainly accompany both storms, and north and west of the track of these storms, there will be disruptive snows coming out of the Rockies and focusing on the northern Plains and the Upper Midwest. Overall, this is not a break in the stormy weather pattern, just a relaxing of the severe cold. Do I think the worst is behind us? I guess that's possible in the Northwest, but I highly doubt it for most places. Winter has truly just begun! While the days are now growing longer, and there are just 88 days left until spring, the old adage is that as the days grow longer, so the cold grows stronger. If you doubt that, just check the average temperatures at most locations across North America. They are still four to five weeks away from reaching rock bottom. We're getting close, but we're not that close. Posted by Joe Lundberg on Monday, December 22, 2008 11:30 AM

For the Montreal area it looks like the snow storm spilt the island in half. Western part received anywhere from 15cm to 18cm and the eastern part received anywhere from 20 cm to 30 cm locally.

I WISH MAINE WAS IN MONTREAL TODAY CHECK OUT THIS FORCAST !!! HEAVY SNOW WILL CONTINUE TO OVERSPREAD THE REGION OVERNIGHT WITH SNOWFALL RATES UP TO 2 INCHES PER HOUR. THE SNOW WILL DIMINISH BY MIDDAY MONDAY. TOTAL SNOWFALL AMOUNTS WILL RANGE FROM 16 TO 22 INCHES WITH AMOUNTS OF 22 TO 28 INCHES FROM BAXTER STATE PARK TO THE HOULTON REGION. IN ADDITION TO THE HEAVY SNOW...WINDS ARE EXPECTED TO INCREASE TO SPEEDS OF 25 TO 35 MPH OVERNIGHT THROUGH MONDAY MORNING. GUSTS OF 40 TO 45 MPH CAN BE EXPECTED WHICH WILL LEAD TO WHITEOUT CONDITIONS. A BLIZZARD WARNING MEANS SEVERE WINTER WEATHER CONDITIONS ARE EXPECTED. THIS STORM WILL HAVE AN EXTREME IMPACT ON THE WARNING AREA. VERY STRONG WINDS COMBINED WITH HEAVY SNOW WILL CREATE POTENTIALLY DEADLY OUTDOOR CONDITIONS. WHITEOUTS...DEEP SNOW DRIFTS AND FROSTBITE OF EXPOSED SKIN CAN BE EXPECTED. THATS BEETWEEN 55 CM AND 70 CM OF SNOW !!

Well its just to bad Montreal did not reach 30 cm.I really would have wanted 1 foot of snow. But i guess its gonna be the next time around.

Noaa just elavated there pricip totale by one inch more, and this is for northern new york. This Afternoon: Snow. The snow could be heavy at times. High near 18. East wind around 6 mph. Chance of precipitation is 100%. Total daytime snow accumulation of 5 to 9 inches possible. PUTTING ENTIRE CWA UNDER NORTHERLY RETURN FLOW. MDLS KEEP AMPLE QPF PINWHEELING AROUND LOW INTO THE AREA FOR MORNING HRS. WILL CONTINUE MENTION OF SEVERAL ADDITIONAL INCHES EXTRA SNOWFALL...ESPECIALLY FOR NORTHERN ZONES. Just remember the second low still has to develop and once it does it will give Southern Quebec the extra 10 cm it needs for 30 cm.Moisture will stream from this low into Southern Quebec.

snow grains were reported in laval 20 min ago.

WINTER SOLSTICE BEGAN TODAY AT 7:04 AM. HAVE A GOOD WINTER !!! BONNE HIVER !!

This is the radar loop and the 1st storm is tracking north, north east The second low pressure still has to form. LIEN.. http://www.intellicast.com/National/Radar/...47&animate=true

Low pressure will track close to the Bay of Fundy and this kind of track usually gives the most pricip for the Montreal area as the return flow comes right along the St. lawrence and down to Montreal. 20 CM TODAY. ANOTHER 10 CM EARLY MONDAY MORNING FROM THE RETURN FLOW.IVE SEEN THIS BEFORE AND WILL SEE IT AGAIN

I think you will be surprised by the amount Montreal will get and that will be close to 30 cm Shawn. I dont think 20 cm will be enough

montreal-est nuageux -14.6c 8:06am montreal -east cloudy -14.6c 8:06am radar...

How much inches of snow would it mean for Montreal ? Combien de pouces de neige ça voudrait dire pour Montreal ? Im still sticking with 30 cms the reason with this is that once the coastal system tracks near the Bay of Fundy. There will be a return of moisture running along the St. Lawrence from the system and that will give us a 10cm on top of the 20cm from sunday.

More global warming !!! over 1500 records broken !!! http://iceagenow.com/Record_Lows_2008.htm

Where is global warming ???? Severe Cold Wave to Hit Europe By Joe Bastardi, Senior Meterologist at accuweather.com ______________________________  19 Dec 08 (Excerpts) The development of a major blocking high pressure system over the north Atlantic and its subsequent backing west is about to throw most of Europe into the coldest winter weather pattern in many a year Temps over the next month or so are liable to average 6-10 degrees F below normal over the center part of the continentIntuitive with this is the likelihood of more than normal snow and ice I wish to point out, with no malice intended, that the two countries with major scientific organizations pushing the global warming idea, Britain and the UKMET and the US with NOAA have been burned by the cold that has developed here. NOAA had a December forecast for a warm central US for November that they were forced to revise and the UKMET forecast for a rather bland winter for Europe speaks for itself. Its anything but bland. If an enemy is vanquished, it should not be able to launch attacks of this magnitude. See entire article: http://www.accuweather.com/ukie/bastardi-e...ner=accuweather

NOAA JUST BOOSTED THERE SNOW TOTALS UP BY 3 INCHES.

Well it looks like 30 cm of snow for the Montreal area. Models now lowering heights and very deep low pressure will form and head for the Bay of fundy by early monday morning . This type of track is the one that gives the most snow for southern Quebec.

It looks like global warming was on earth since humans walked the planet. Co2 does have a effect on the earths temp but to what level is the question Frankly in 30 years from now maybe we will be dealing with global cooling !!! Thats what happened in the 1970s and 1910s then the 1930s came along and it was global warming. Please make up your mind is it warming or cooling, well what ever the answer is nature will always balance itself. Humans started causing global warming 5,000 years ago, UW study says By Lee Bergquist of the Journal Sentinel Posted: Dec. 17, 2008 Global warming didn't start with the industrial revolution, but began 5,000 to 8,000 years ago with large-scale agriculture in Asia and extensive deforestation in Europe, according to new research by University of Wisconsin-Madison scientists. Using powerful supercomputers and advanced climate models, the researchers concluded that methane and carbon dioxide - the building blocks of global warming - began rising with the introduction of rice cultivation and large-scale tree removal. "I think that the take-home message is that this hypothesis shows that climates are extremely sensitive to small variations in greenhouse gases," said Steve Vavrus, a climatologist at UW's Center for Climatic Research. Vavrus and his colleagues John Kutzbach and Gwenäelle Philippon were to discuss their research today at a meeting of the American Geophysical Union in San Francisco. The work of the UW team also shows that the build-up of greenhouse gases over thousands of years has prevented the start of a new glacial age. Ice ages have occurred at regular 100,000-year intervals over the last 1 million years, they said, mirroring predictable changes in the orbit of the Earth, known as Milankovitch cycles. Had the man-made gases not been emitted into the atmosphere, portions of the arctic and some mountainous regions would contain more permanent snow and ice than they do today, Vavrus said. The researchers used data from other scientists who have been measuring oxygen and other gases trapped in ice core samples from Antarctica that are 850,000 years old. The air samples from 5,000 to 8,000 years ago contained unmistakable levels of methane and carbon dioxide gases. Methane levels rose from decomposing vegetation in terraced rice paddies, Vavrus said. The rising levels of carbon dioxide came from deforestation known to have taken place in Europe. Three different climate models were used. The researchers removed the amount of greenhouse gases that humans sent into the atmosphere, based on the ice core samples. The models show more permanent snow and ice cover in Canada, Siberia, Greenland and the Rocky Mountains. Vavrus said the research supports theories first put forward by William F. Ruddiman, a paleoclimatologist at the University of Virginia.

Joyeux Noël et Bonne Année à tout le monde! Happy holidays and a Happy New Year to all!

THE AMOUNTS SHOWN ABOVE HAVE A GOOD CHANCE TO BE REACHED.COASTL LOW TAKES OVER FULLY AND LIFTS INTO THE MARITIMES. THIS WILL SET UP THE SECOND PORTION OF SNOWFALL ACCUM AS NORTHERLY WINDS SET UP RIGHT INTO MONDAY. ADDITIONAL ACCUM OF 8 TO 15 CM POSSIBLE BFR PRECIP TAPERS OFF BY MON AFTNOON. WE SHOULD REACH 30 CM BY MONDAY AFTERNOON.

The latest computer models show this next potent storm will give Montreal anywhere from 25cm to 35 cm of snow. Northern New York is expecting anywhere from 12 to 18 inches . From NOAA for Northern New York region statment... ...WIDESPREAD MODERATE TO HEAVY SNOWFALL EXPECTED. DUE TO CURRENT WINTER WEATHER HEADLINES IN PLACE...HAVE OPTED TO FOREGO ISSUANCE OF ADDL HEADLINES FOR THIS EVENT TO MINIMIZE CONFUSION. HOWEVER...WATCHES AND/OR WARNING WILL LIKELY BE ISSUED ON SATURDAY...ESP GIVEN SUCH HIGH CONFIDENCE IN OVERALL PATTERN.-- End Changed Discussion --
