The weather phenomenon La Nina will bring Canada the coldest winter in nearly 15 years, Environment Canada warned Friday.

Environment Canada's temperature forecast shows the majority of the country will experience a "temperature anomaly" of below-normal temperatures through the months of December, January and February.

Much of Nova Scotia, Saskatchewan, Alberta and parts of British Columbia and southern Ontario will also see above-normal precipitation.

David Phillips, senior climatologist with Environment Canada, told The Canadian Press that the temperature and precipitation abnormalities are likely the result of the weather phenomenon La Nina.

La Nina, meaning the little girl, is the appearance of cooler-than-normal waters in the eastern and central Pacific Ocean.

"La Nina is thought to occur due to increases in the strength of the normal patterns of trade wind circulation," Environment Canada's website says.

"For reasons not yet fully understood, periodically these trade winds are strengthened, increasing the amount of cooler water."

These cooler waters result in wetter-than-normal conditions in the northern hemisphere and changes to the jet stream over North America.

"The shifted jet stream contributes to large departures from the normal location and strength of storm paths. The overall changes in the atmosphere result in temperature and precipitation anomalies over North America which can persist for several months," Environment Canada says.

In the past, La Nina caused drought and floods around the world. It also whips up more hurricanes in the Atlantic.

The effects of the weather phenomenon have already been felt in parts of Western Canada. Earlier this month, a fierce storm dumped nearly 80 centimetres of snow on Whistler, B.C. over 48 hours. The massive snowfall prompted management at the famous Whistler Blackcomb ski hill to open one week ahead of schedule.

Yep-- thats what old Bastardi from accuweather has been saying...And he thinks thats whats going to give most of the US east of the Rockies one of the warmest winters in history :shock: :D

Only thing I didn't like is that I'm sitting about on the dividing line- and my weather could bounce back and forth either way----But he thinks the most cold (and hes calling it SEVERE cold) will continue to stay north of the 49th most of the time ...

Despite the early chill in the East and the National Weather Service forecast predicting a colder winter than last, Bastardi believes this could rival the winter of 2001-02 for warmth centered in major population areas--mostly the East, South, Midwest and Great Lakes regions.

The only colder-than-normal areas will be the less populated Pacific Northwest and northern Rockies. Bastardi points out that last year, the coldest period was centered in the East during the heart of winter. February was the coldest ever in parts of the Midwest, and December was what tipped the scale to warmer than normal over the three-month period. This winter; however, will be warm in most of the nation from the Plains eastward, where much of the population resides.

Unlike last winter, when the AccuWeather.com forecast indicated that the warmth of December and early January would turn on a dime, when the warmth returns this December it may last all of the way through February. In fact, in some places, the wildest weather may be during the next three or four weeks, and then again in March or April as a late spring may be in the making for much of the East.
