They say time heals all. When it comes to this"weather event" that I’ve been watching since Tuesday, time has not been our friend.
I could see early on, that this developing disturbance would bring a good blast of winter, but as the energy comes together in the atmosphere and the track of the systems, yes systems, becomes more certain, it’s looking more like a blizzard than a smple blast of winter. In fact this storm is taking on "text book" characteristics of a true Nor’easter!
Back to the issue of the “two systems”. The first is a very tightly wound winter storm making its way up the Ohio Valley. Heavy snowfall warnings have been issued for parts of southern Ontario, including Toronto; they could get as much as 25 cm of snow… that won’t be pretty.
This morning it looks like this primary storm tracking across the U.S. Midwest will remain well organized as it cross Lake Erie then heads toward Lake Ontario before getting absorbed by the rapidly strengthening coastal storm later Friday.
The track of the coastal low and the timing of the energy associated to with the primary storm is ideal for significant snowfall across the Maritimes. With cold air in place, the snowfall numbers will be impressive. To make matters worse, the snow will be accompanied by strong northeast winds that will cause whiteout conditions Saturday into Sunday.
Finally, those strong northeasterlies over the gulf of St. Lawrence will bring on higher than normal water levels, and could push pack ice into north and northeast facing shorelines.
So that’s the storm situation as it stands right now. Given the current track and phasing of the storm systems, I’ve prepared the following is a list of snowfall amounts for various regions of the Maritimes. These are storm totals – beginning late Friday and tapering off Sunday morning.
Edmundston: 2 cm
Miramichi: 5 cm
Fredericton: 15-20 cm
Saint John: 30-40 cm
Moncton: 25-30 cm
Charlottetown : 20-30 cm
Amherst: 30-40 cm
Cheticamp: 25-35 cm
Greenwood: 35-40 cm
Halifax: 35-45 cm
Truro: 35-45 cm
South Shore: 35-40 cm
Yarmouth: 30-40 cm
Sydney: 30-40 cm
We'll know for sure on Monday ;)
