Our white Christmas is guaranteed here in southern Quebec and most of Ontario as well as Northern New England. We will freshen up the snow pack today with about 5-8cm of snow region wide with the exception of eastern Ontario which will see less. The much anticipated snow has been slow to arrive, in the forecast since late Sunday. Expect a plume of moisture from a coastal storm in Atlantic Canada to spread west into southern Quebec this afternoon. Snow will begin after lunch and taper off by midnight with around 5cm in the city and slightly more east of the city in Sherbrooke and Quebec City. This morning a little light freezing drizzle is being reported in the St. Lawrence Valley of New York and Ontario with some slick spots on area roads. Once the snow ends tomorrow high pressure will build in and control the weather right through the holiday weekend with ideal travel conditions.
The same can't be said for the US where a powerful Pacific storm has produced nearly 200 inches of snow in portions of the Sierra Nevada mountains in California and Nevada with up to 20 inches of rain in the lower elevations. Today the rain continues with strong thunderstorms and another 2-4 inches of rain expected in Southern California. That storm will lift over the Rockies and produce snow and rain across the central portion of the country and into the southeast through Christmas weekend. it may threaten the east coast by early next week, but it appears at this time that is will stay well east of Montreal.
Meanwhile Air Canada resumed flights to London yesterday, nearly 5 days after a snowstorm shut down air and road travel in large parts of Europe.
Our snow is being generated by a strong coastal storm that has been pounding regions of Nova Scotia, PEI, New Brunswick and Eastern Quebec. Winds have gusted over 100km/h and a large and powerful storm surge has produced high waves and tides and widespread. Storm Surge Warnings remain in effect for most coastal regions surrounding the Gulf of St. Lawrence. These conditions will persist into Thursday.
