Snowfall amounts across extreme southern Manitoba from Monday and early Tuesday were quite impressive. Unofficial totals courtesy of Environment Canada.
Here is my latest interpretation of the ECMWF bi-weekly extended long-range forecast output for North America. You can also follow my weather commentary on twitter @BrettAWX
The model keeps the northeast Canadian blocking pattern in place through the week of March 18-24, which keeps the colder-than-normal conditions in place from the Prairies through southern Ontario and into the eastern half of the U.S. The model shows the block weakening by the last week of March as colder air returns to Alaska, which normally means an influx of Pacific air coming from west to east across parts of southern Canada and the U.S. and perhaps a little spring.
By the way, short-range models are coming into pretty good agreement now with the storm pushing from the Midwest to the Middle Atlantic coast over the next two days. This storm will be miss Ontario and Quebec as it tracks too far to the south under the northeastern Canada block. I will discuss any potential impacts for southern Nova Scotia later Tuesday after I finish drawing up the weather graphics for AccuWeather.com.

My latest thoughts on the weather pattern into next week
When will the cold leave the East? More storms for the West?
