Snowstorm for portions of Quebec, Ontario & NE

From AccuWeather, snow accumulations expected from storm 1.
There is plenty of weather to talk about this morning as two separate areas of low pressure are forecast to come together off the east coast of the US and produce a major storm for New England and Atlantic Canada. I will try to bring some order to this, as always when I am excited about the weather, I tend to be all over the place with the blog!

We will start with storm one over Texas that will move towards Lake Erie later today. This system has prompted winter storm warnings for southern Ontario from Windsor up towards Kingston. Snow will start tonight and become heavy on Friday. Amounts in the order of 25cm are forecast for the region with perhaps 15cm for the Ottawa Valley. Travel on Friday will be very difficult along the 401 corridor and especially in the GTA.

The strom could be historic in southern New England including Boston and the Cape.

By Friday a potent storm will begin developing near North Carolina and this system will begin to absorb the fist low. It will move northeast towards Cape Cod while bombing out. This type of storm can loose as much as 24mb of pressure in 24 hours as it deepens rapidly. The intense low pressure area may be historic in places along the I-95 corridor from Providence up towards Portland. Heavy snow, strong winds up to hurricane force in places, coastal flooding and even thunder are forecast from Friday afternoon into Saturday morning. This storm will produce 1-2 feet of snow in a wide swath from southern New England north and west towards the Adirondacks and southern Quebec. For Montreal expect a few centimetres/inches of snow from the first storm from late tonight into Friday morning. There may be a lull in the snow before a second wave arrives from the southeast by late Friday. By Saturday morning we could be looking at 25cm (10 inches) of snow from the metro area south with more along the US border and into the Townships. No warnings are in place here at this time. A winter storm watch is in effect for the US side of the St. Lawrence Valley as well as northern New York and all of Vermont. There are still more details to iron out, but make no mistake whether you are planning to travel by car or air Friday, it will be very difficult across all of the east.

I will update this storm as the day moves along on Twitter with a full update by 7pm this evening.
